1. Comparison Of Single And Stack Pinning Techniques For Mid Shaft Femoral Fracture In The Dog

by Kamran Akhtar | Dr. Mazhar Iqbal | Dr. Muhammad Arif | Dr. S | Faculty of Veterinary Sciences.

Material type: book Book; Format: print Publisher: 1995Dissertation note: The incidence of femoral fracture is higher than that of other long bones in clogs. Immobilization of Fernoral fractures by external method of fixation is almost impossible due to angulation of the hind limbs, thickness of thigh musculature and difficulty of controlling motion in the hip joint. This type of orthopeadic ailment can he handled successfully with hone splintage principle which, includes the use of compression plates, cerciage wires, and intrarneclullary pins. In this project stack pinning and single intramedullary pinning with hemicerciage wires were used to treat midshaft transverse femoral fractures n the clog. The procedure was conducted on 20 mongrel dogs of either sex, divided into two groups of 10 clogs each . In group I the surgically created mid shaft femoral Fracture was immobilized using single intramedullary pin with hemicerclage wires. Whereas in group II the fracture was immobilized with stack pinning. First pin was introduced in a retrograde and the second pin in a normograde fashion. All the dogs were kept in Kennels For a period of sixteen weeks and results were collected on the basis of clinical and radiographic evulations. All the clogs were euthanisecl at the end of experimental period and operation sites were explored to find out the gross changes The analysis of the results clearly indicated that intramedullary pinning with hemicerclage wires was a better choice over stack pinning for repairing mid shaft transverse femoral Fractures.

2. Evaluation Of Uretero Jejunocolostomy For Urinary Diversion In The Dog

by Aneeta Hussain | Dr. Mazhar Iqbal | Dr. Muhammad | Dr. Muhammad Arif Khan | Faculty of Veterinary Sciences.

Material type: book Book; Format: print Publisher: 1995Dissertation note: Urinary diversion is the procedure adopted for urine expulsion in the most natural way, in the absence of the urinary bladder. In the beginning of the twentieth century many surgeons of human side as well as veterinarians used intestines for performing urinary diversion. They adopted many methods for this purpose but only a few were found to be successful. These procedures were used to relieve the animal from malignant bladder carcinomas, severe damage of bladder and urethra during accidents, and extrophy of urinary bladder etc. These diseases mostly cause urinary discomfort, incontinence of urine and painless heamaturia and cystectomy becomes a necessity. During this study fifteen healthy dogs of either sex were used. Laparotormy was performed under aseptic precautions. The small intestine was exteriorized through. the incision and the terminal portion of jejunum was identified. A 6-8 cm portion of the jejunurn was selected and milked to clear it of from the feacal materials. This portion was isolated from rest of the intestinal tract with the Doyen's intestinal clamps and was cut off with its mesenteric blood supply remaining intact. The continuity of the small bowel was restored by end to end anastomosis. The vent in mesentery was closed by simple continuous sutures. The isolated Jejunal segment was wrapped in a piece of gauze soaked in normal saline. The urinary bladder was emptied in females by gentle digital pressure and in males by mean of a disposable syringe. The ureters were amputated obliquely down to the trigone area and bladder was excised. Afterwards one end of the Jejunal segment was closed by lambert sutures. A small hole was created on the right side at the upper third portion which cut through the first three layers. From this hole a 2 cm long submucosal tunnel was created going towards the open end of the segment. The cut end of the ureter was sutured to the mucosa of the Jejunal segment using 3/o prolyene simple interrupted sutures. On the left side of the segment the other ureter was implanted similarly. A longitudinal incision equal to the diameter of jejunal segment was made at the antimesenteric border of the distal portion of colon. The open end of jejunal segment was implanted here using 3/0 chromic catgut via side to end anastomosis with simple I nierrupted crushing sutures, thus creating an intestinal bladder. Finally the abdomen was closed in routine manner. It was concluded on the basis of this study that: 1. Viable segment of small bowel with blood and nerve supply intact can be used as a bladder. 2. Voiding occurs in the most natural possible way without any need of an external reservoir. 3. There was no ascending infection, so kidneys remained normal. 4. Use of antibiotics for rest of the life was not needed. The successful attempt of making a new bladder strengthened the belief in cases where there was no other way of saving the animal's life except surgical intervention. So the veterinarian should involve himself with the core of his heart in the operative procedure with the aim of achieving good results. Whether he loses or gains, he must have a satisfaction of being loyal to his profession. Availability: Items available for loan: UVAS Library [Call number: 0423,T] (1).

3. Comparative Evaluation Of Tension Band Wire And Steel Suture For Repair Of Transversepatellar Fracture In The Dog

by Sarfaraz Ahmad, M | Dr. Muhammad Arif Khan | Dr. Mazhar Iqbal | Dr. Mubashar | Faculty of Veterinary Sciences.

Material type: book Book; Format: print ; Literary form: not fiction Publisher: 1994Dissertation note: The fracture of patella usually falls in a special type of fracture, which is not treated by ordinary limb and bone fixation devices. Hence emphasis is given to counteract the distracting forces and to convert them into compressive forces to achieve the desired effects. Different types of internal fixation devices have been tried in the past for the repair of avulsion fractures like Tension Band wire, compression screws, compression plates, an steel sutures. This study was conducted on 20 mongrel dogs divided into two groups of 10 animals each. These groups were designated as group A and group B. Two methods, Tension Band wire and square steel suture were used for the repair of transverse patellar fracture in dogs. In group A, the right patella was surgically exposed, fractured and repaired by Tension Band wire with Thomas Splint on the same limb when the operated dog started bearing weight on its operated leg, the left patella was exposed and repaired using same technique but without Thomas Splint. In group B the right patella was repaired by square steel suture with Thomas Splint. After six weeks, the left patella was operated and repaired using same technique but without Thomas Splint. The dog of each group was kept for a period of 16 weeks after surgery. The results were obtained on the basis of their clinical and radiographic picture. The results of this study indicate that the use of steel suture is a better fixation device for the repair of transverse patellar fracture.

by Sajid Ijaz | Dr. Muhammad Arif Khan | Dr. Mubasher | Dr. Muhammad Ashraf | Faculty of Veterinary Sciences.

Material type: book Book; Format: print ; Literary form: not fiction Publisher: 1995Dissertation note: These days the scope of anaesthesia is consistently increasing due to increase in surgical patients in veterinary practice. This change in trend is due to the awareness of the owners to different surgical problems and their solutions. They do not hesitate to get their animals treated with modern equipments and highly expensive medicine. To meet this challenge and demand of the owners, veterinary surgeons are taking keen interest to get the advanced knowledge and latest information of modern equipments and their usage in veterinary practice. In the past surgery was performed by making temporary insensibility by asphyxiation, cerebral concussion by striking wooden bowl placed over the head with a hammer and a regional anaesthesia was attained by compression of nerves and blood vessels of the region to he operated upon. But these days different sedative and anaesthetic agents are being used to make the animal desensitize from all external stimuli. These drugs are available in volatile, nonvolatile and gaseous forms. The usage of anaesthetic agent entirely depends upon the species, age, weight, temperament of the patient, nature of the operation to he performed, cost and availability of the drug. In this project three different combinations were tried in thirty animals of equine species to find out the best selection for major surgical interventions. The animals were divided into three groups often animal each. These groups were designated as Group A, B and C. Group A was anaesthetized with XylazineiPentothal sodium, Group B with Acepromazine/Pentothal sodium and Group C with Diazepam/Pentothal sodium. The efficacy of these combinations was measured on the basis of nature of induction, recumbency period, nature of recovery, different body reflexes, recording temperature, pulse, respiration, and statistical analysis of results. The analysis of the results collected during this study clearly indicated that a combination of cliazepam with pentothal sodium was a better selection for anaesthetizing equine patients. This study aslo proved that combination comprising of xylazine and pentothal sodium could he used for minor surgical interventions as it produced light surgical anaesthesia. It was concluded that a combination consisting of diazepam and pentothal sodium should be used for all types of major surgical procedures in equine practice.

by Aamir Aslam, Ch | Dr . Muhammad Arif Khan | Dr . Asim Aslam | Dr . Muhammad Sarwar Khan | Faculty of Veterinary Sciences.

Material type: book Book; Format: print ; Literary form: not fiction Publisher: 2000Dissertation note: There are different joint problems in dogs but out of all the incidence of hip joint problems is higher. There are different problems of hip joint mainly, hip dysplasia, leg-calve-perthes disease, degenerative joint disease, irreparable fracture of acetabulum, femoral head and neck. Different methods are used as a treatment for above mentioned ailments. The methods used for such type of problems are categorized into conservative, palliative and surgical. The surgical treatment is further divided into (1) salvage procedure i.e. femoral head and neck excision (2) total hip replacement. The present project was launched to find out the efficacy of two approaches used for the femoral head and neck excision in dogs. The study was conducted on 18 mongrel dogs of either sex ranging in weight from 20.25 kg, which were divided into three groups of 6 dogs each. In group A femoral head and neck excision was performed by using craniodorsal approach, whereas in group B ventral approach was used for the same procedure. Group C was kept as control in which the femoral head was luxated by using either approach. All the dogs were kept in kennels for a period of sixteen week and results were collected on the basis of clinical and radiographic evaluations. All the dogs were euthanized at the end of experimental period and operation sites were explored to find out the gross changes and also to find out the evidence of false joint formation in the muscles. The analysis of results clearly indicated that craniodorsal approach was a better procedure than ventral approach for the femoral head and neck excision in dogs.

6. Comparative Efficacy Of Various Suturing Techniques For End To End Anastomosis Of Jejunum In Dogs

by Abdul Rauf, Rana | Dr. Muhammad Arif Khan | Dr. Muhammad | Dr. Muhammad Athar Khan | Faculty of Veterinary Sciences.

Material type: book Book; Format: print ; Literary form: not fiction Publisher: 2002Dissertation note: Diseases of gastro-intestinal tract like intestinal foreign body, intussusception with obstruction and adhesion, gangrene, volvulus and abdominal trauma amenable to surgical correction with enterectomy, segmental resection and end-to-end anastomosis had been a nightmare with both human and veterinary surgeons. Most of the techniques evolved in the past were not commensurate with the criteria of physiological restoration of normality, absence of leakage and minimal lumen stenosis. The present study was undertaken to compare the three suturing techniques viz; simple interrupted crushing sutures, simple interrupted lembert sutures and simple continuous lembert sutures for end-to-end anastomosis. Study was conducted on 12 clinically healthy dogs of mixed breed divided equally into three groups. The versatility and comparison of the techniques were evaluated on the basis of clinical parameters, hematological value, radiographic examination and postmortem findings. It was observed that simple interrupted crushing technique was comparatively more compatible and superior due to its simplicity, economical, less lumen reduction as compared to other techniques viz; simple interrupted Lembert technique and simple continuous Lembert technique. The results of this study clearly indicated that the use of simple interrupted crushing sutures has an edge over the simple interrupted lembert suture and simple continuous lembert sutures for end-to-end anastomosis of jejunum in dogs.

7. Comparative Study Of Flank Vs Midline Approach For Overiohysterectomy In Cats

by Mudassir Ahmad Rana | Dr. Muhammad Arif Khan | Dr. Asim Khalid Mehmood | Prof. Dr. Nasim | Faculty of Veterinary Sciences.

Material type: book Book; Format: print ; Nature of contents: biography; Literary form: Publisher: 2005Dissertation note: Ovariohysterctomy is one of the most commonly performed operation in cats and is indicated for both medical and behavioral reasons. The most common indication of ovariohysterectomy is elective sterilization which avoids all objectionable sexual behaviors and over population. Ovariohysterectomy is the treatment of choice for most uterine diseases and it greatly reduces risk of mammary neoplasia. The method of performing ovariohysterectomy in cats must be affordable, safe, reliable & convenient. In the past different approaches have been tried for ovariohysterctomy in cats viz. linea alba(ventral midline) and vertical flank. But the relative efficacy of the approaches has not been determined in the past in our conditions. The objective of our study is to compare and evaluate these two approaches in our environmental conditions. The Flank approach was found to be relatively better than the Ventral midline approach in our conditions in terms of convenience, reliability, safety with rapid recovery and less postoperative complications.

8. Prevalence Of Caprine Mycoplasmosis In Different Areas Of Pakistan

by Waseem Shahzad | Prof. Dr. Mohammad Sarwar Khan | Prof. Dr. Muhammad Arif Khan.

Material type: book Book; Format: print Publisher: 2010Dissertation note: A study was conducted to characterize caprine mycoplasma species and to know its prevalence in different areas of Pakistan during 2006 to 2007. For this purpose a total of 1440 different samples such as nasal discharge, pleural fluid, lung piece, synovial fluid, and milk samples (1180), and 260 serum samples were collected from clinically affected goats of different breeds, age and sex. These samples were collected from twelve districts including Mansehra, Peshwar, Swabi, Kohat, Abbottabad, Dera Ghazi Khan, Quetta, Pishin, Jhang, Sargodha, Lahore and Faisalabad with 6 union councils (UC) in each district. Twenty samples of different nature were collected from each of union council. These samples were subjected to cultural isolation, Growth inhibition test (GIT) using rabbit polyclonal antiserum against Mycoplasma mycoides subspecies capri, latex agglutination test (LAT) for the detection of Mycoplasma capricolum subspecies capripneumoniae and polymerase chain reaction (PCR). One twenty one samples out of 1180 showed turbidity in PPLO broth whereas out of these 121 samples 58 grew on PPLO agar. All 58 field isolated organisms showed positive reaction to GIT. None of the serum sample showed a positive reaction with LAT kit. Thirty five samples out of 1180 prior to culturing were positive for Mycoplasma mycoides cluster through PCR and identified as Mycoplasma mycoides subsp. capri (Mmc) through DNA sequencing, whereas 58 samples were positive with this technique after culturing. Prevalence of mycoplasmosis in hilly and plain areas (5.8 and 4.5 % respectively) is not significantly higher as compared to semi desert and sub hilly areas (3.3 and 2.9 % respectively) which may be due to chance alone. Furthermore, the adult group-3 (age > 1 year) has significantly lowest prevalence (2.7 %) of Mmc as compared to age group-1 (age < 181 days) with 5.1 % prevalance and age group-2 (age: 181 to 365 days) with 4.4 % prevalence. This difference may be due to chance but not areal difference. Similarly prevalence (4.7%) of mycoplasmosis in female goats is not significantly higher as compared to males (3.2%). Beetal, Piamiri, Beetal teddy cross, Baltistani and Desi breeds of goats showed higher prevalence only by chance as compared to other breeds in the areas under study. Saponin inactivated vaccine was prepared from this field strain and found to be effective against Mycoplasma mycoides subsp. capri in goats. This study focuses on characterizing the interaction of M. ovipneumoniae with ovine PBMC using carboxy-fluorescein-succinimidyl-ester (CFSE) loading and flow cytometry to measure lymphoid cell division. M. ovipneumoniae induced a strong in vitro polyclonal suppression of CD4+, CD8+, and B blood lymphocyte subsets. The suppressive activity could be destroyed by heating to 60 ºC, and partially impaired by formalin and binary ethyleneimine treatment that abolished its viability. The activity resided on the surface-exposed membrane protein fraction of the mycoplasma, since mild trypsin treatment not affecting viability was shown to reduce suppressive activity. Trypsintreated mycoplasma regained suppressive activity once the mycoplasma was allowed to re-synthesize its surface proteins. Implications for the design of vaccines against M. ovipneumoniae are discussed. Availability: Items available for loan: UVAS Library [Call number: 1188,T] (1).

9. Comparative Efficacy Of Intravesical Mucosal And Extravesical Apposition Techniques For Ureteroneocystostomy in Dogs

by Muhammad Talha Sajjad | Prof. Dr. Muhammad Arif Khan | Dr. Aneela | Dr. Shahan Azeem.

Material type: book Book; Format: print ; Literary form: not fiction Publisher: 2011Dissertation note: This project was designed to evaluate the comparative efficacy of two different techniques of Ureteroneocystostomy for ureteral reimplantation in dogs. Sixteen stray dogs were selected and were divided into two groups i.e. group A & B, comprising eight animals each. The efficacy of the procedures was evaluated on the basis of physical examination, serum evaluation for creatinine & urea, contrast radiography and post mortem findings. The surgery was conducted through ventral midline celiotomy from umbilicus to a variable distance caudally under general anesthesia in both the groups and urinary bladder was exteriorized in both the groups. In group A, longitudinal incision was made near the bladder dome, a mosquito hemostat was passed from the surface of the bladder through the bladder wall at an oblique angle then the ureter was brought to the level of the bladder mucosa incision. A 6-0 Polyglactin 910 (Vicyrl,Jhonsons & Jhonsons Pharma) suture with double needles was then placed at each apex of the spatulated ureter and the full-thickness of ureter anastomosed to the bladder mucosa in one layer with a continuous, nonlocking stitch. In group B, two small incisions were made at the outer part of the bladder wall until the mucosa was seen through the cuts. Then a submucosal tunnel was dissected between them and the graft's ureter was introduced. Once the ureteral end has been spatulated, a reabsorbable 4-0 suture thread with independent needles at each end was passed (each needle goes from the outer to the inner side of the ureteral wall. Afterward, both needles were advanced into the bladder by the creation of a mucosal incision at the distal hole; these two needles then transfixed the bladder wall from inside about 2 cm distally. During knotting of the suture (outside the bladder) the distal ureter was pushed to the bladder wall that it anchored against the mucosa. The results of this study clearly indicated that both techniques are equally effective for the reimplantation of the ureter to bladder but an extravesical ureteroneocystostomy (Modified Lich Gregoir) has an edge over in intravesical mucosal apposition technique (Modified Lead better-Politano) in terms of effectiveness , safety and minimum postoperative complications.

10. Epidemiology Diagnosis And Chemotherpy Of Strangles In Equines

by Muhammad Ijaz | Prof. Dr. Muhammad Sarwar Khan | Prof. Dr. Muhammad Arif Khan.

Material type: book Book; Format: print Publisher: 2010Dissertation note: Strangles is an infectious malady of equidae characterized by upper respiratory tract infection, dysponea, anorexia, regional suppurative lymphadenitis and causes high morbidity and low mortality. Considering the significance and utilization of equines in our country and the substantial losses rendered by Strangles, the present project was designed to study epidemiology, diagnosis and chemotherapy of strangles in Lahore and Sargodha districts of the Punjab province in Pakistan. The present study comprised of five phases. In phase-I, epidemiology of the disease including prevalence, variations in SeM, SzPSe and Se18.9 proteins and mortality rate were studied in Lahore and Sargodha districts. For epidemiology, nasal swabs and pus samples from the affected lymph nodes of 500 equines (nr=250 horses, rutz250 mules) suspected for strangles were collected and cultured for identification of S. equl. The collected samples were processed at Medicine and Microbiology Laboratories of the University of Veterinary and Animal Sciences, Lhore, Pakistan and Gluck equine research center, Department of Veterinary Science, University of Kentucky, USA. Out of 250 horses and 250 mules, 113(45.2%) horses and 99 (3 9.6%) mules tested positive for S. equi. on the basis of culture. Number of S. equl isolates were significantly higher (P<0.05) in pus samples taken from sub-mandibular lymph nodes as compared to nasal discharge samples. The difference was significant (P<0.05) among mules of different age groups. The highest prevalence of strangles was recorded in horses and mules less than 2 year of age as compared to those having age more than 2 years. In the present study, prevalence of strangles round the year in horses and mules were also calculated and it was found to be the highest during the months of February, March, April and May while few cases were seen during the months of January, June and July and no cases were observed during others months. The significant difference was observed (p<O.O5) among the prevalence levels of strangles in different months of the year. Similarly when compared the prevalence of strangles in different seasons of Pakistan i.e. summer, winter, spring and autumn. The highest prevalence rate was recorded during the spring season. The prevalence on the basis of Polymerase chain reaction (PCR) of S. equi in horses and mules was also recorded. Out of 250 horses and 250 mules tested, 122(48.8%) horses and 113(45.2%) mules were positive for S. equi. When compared the prevalence rate on the basis of PCR and culture of nasal and pus samples from affected submandibular lymph nodes it revealed that the sensitivity of Polymerase chain reaction appears to be much greater than culture. The culture along with PCR is the best diagnostic technique for S. equi as PCR test does not differentiate between dead and live bacteria, hence a positive test may not correlate with active infection; therefore, a positive culture may be necessary to confirm the diagnosis. In this phase of epidemiological study of disease, effect of selective pressure of allelic diversity in SeM of S. equi on immunoreactive proteins SzPSe and Se 18.9 was also studied. The aim of this study was to determine whether variations in SeM are accompanied by variations in the immunoreactive surface of exposed SzPSe and secreted Se18.9. Sequences of genes of 25 S. equi alleles isolated from different countries of the world over a period of 40 years were compared. Twenty different SeM alleles were identified including 6 not included in the data base (http:// pubmlst.org/szooepidemicus). Amino acid variation was also detected distal to the N- terminus of SeM. No variation was observed in SzPSe except for an Australian isolate which showed a deletion of one PEPK repeat. The Se 18.9 protein in all 25 isolates of S. equi did not exhibit any variation. Interestingly, only 2 SNP loci were detected in Se 18.9 compared to 93 and 49 in SeM and SzPSe respectively. The greater frequency of mutation in SzPSe compared to Se18.9 may be related to a high rate of recombination of SzPSe and the inclusion of exogenous DNA sequence based on the atypical GC percentage of its central hyper variable region. In horses the mortality rate was recorded as 1.64% whereas the mortality rate in mules having less than 5 years of age was found to be 0.88%. No significant difference (P>0.05) in mortality rate among horses and mules of different age groups affected with strangles was observed. In phase-I! of the present study, carrier status of the horses and mules were studied. Out of 122 horses found positive to PCR, 20 horses (10<2 years and 10 between 2 and 5 years of age) were selected and monitored for 12 weeks. Their nasal swab samples were used for identification of bacteria through culture and PCR on weekly basis. Till the end of 3rd week all horses <2 years of age remained positive but at the end of 4th to 7th weeks there remained positive only 5, 2, 1 and zero horses out of 10, respectively on the basis of culture whereas through PCR at the end of the 4th week all horse <2 years of age were found positive, but at the end of 5th to 10th weeks there remained 7, 5, 4, 2, 1 and zero horses out of 10, respectively. While all the horses aging between 2 to 5 year, were positive up to the 1St week but at the end of 2nd to 8th week out of 10 there were 9, 7, 6, 3, 1, 1 and zero horses respectively positive on the basis of culture but through PCR, all horses were positive till 4th week but at the end of 5th to 9th week number was reduced to 9, 7, 6, 3, 2 and zero. Similarly, out of 113 mules, 20 mules (10<2 year and 10 between 2 and 5 years of old) were also monitored for 12 weeks to study their carrier status. After the end of 2nd week all mules <2 years of age were positive but at the end of 3rd to 6th weeks there remained 7, 3, 1 and zero mules out of 10, respectively on the basis of culture but through PCR at the end of the 5th week all mules <2 years of age were positive, but at the end of 6th to 10th weeks there remained 9, 7, 3, 2 and zero mules out of 10, respectively. While in 2 and 5 year old mules, all were positive up to the 2nd week but at the end of 3rd to 7th weeks there were 6, 4, 2, 1, 1 and zero mules out of 10, respectively on the basis of culture but through PCR, all mules were positive up to 5th week but at the end of 6th to 10th weeks there were 8, 5, 2, 1 and zero. Horses and mules were declared free of infection on the basis of three consecutive negative samples through culture and PCR. From the result of present study, it may be concluded that sensitivity of Polymerase Chain Reaction appears to be much greater than culture for study of carrier status of equines. Moreover, recovered animals should be kept in quarantine period at least upto 9th week because the recovered horses and mules remain carrier for prolonged period of time and can act as source of infection for susceptible animals through periodic shedding of S equi. (comprising 10 horses and 10 mules) for in-vivo trials. Efficacy of the antibiotics was assessed weekly on the basis of negative nasal swab culture. Results of in-vitro antibiotic sensitivity revealed that in horses and mules, S equi was most sensitive to Procaine penicillin followed by ceftiofur Na, cephradine, erythromycin, ampicillin, tetracycline, chloramphenicol, sulfamethoxazole, trimethoprim + sulfdiazine and gentamycin whereas the result of in-vivo antibiotic trials revealed that horses and mules suffered from strangles without abscess formation were most sensitive to Procaine penicillin followed by ceftiofur Na, cephradine and erythromycin whereas animals which developed abscess showed no response. It is concluded from the result of present study that Procaine penicillin is most effective in-vitro and in-vivo antibiotic followed by ceftiofur Na and cephradine. These antibiotics might be used for the treatment of strangles infection. Phase-V, comprised over in-vitro trials of disinfectants. Efficacy of disinfectants, like povidone iodine, 0.6% H2S04, dettol and bleach was assessed. Phenol Co-efficient Test was applied, to ascertain efficacy of these disinfectants, used in, in-vitro trials. Among four disinfectants, povidone iodine was found to be the best one with a phenol coefficient of 1.25 that is greater than phenol i.e. 1.00 while 0.6% H2S04 showed similar phenol coefficient as that of phenol. The phenol coefficient of dettol and bleach were observed as 0.5 and 0.75 respectively. Therefore it is recommended that S. equi is highly sensitive to povidone iodine and 0.6% H2S04.

11. Comparative Efficacy Of Suturing Techniques And Suture Materials For End-To-End Anastomosis Of Small Intestine in Dogs

by Adeel Shahbaz | Prof Dr. Muhammad Arif Khan | Mr. Shahan Azeem | Prof. Dr.

Material type: book Book; Format: print Publisher: 2010Dissertation note: The small intestine is a tube-like structure, which extends between the stomach and largeintestine. It starts at the pylorus and terminates at the cecocolic junction. Small intestine plays an important role in the absorption of amino acids, carbohydrates, fats and electrolytes like sodium, potassium, chloride and bicarbonate ions. Any disease condition of jejunum like neoplasia or devitalization due to foreign body necessitates the resection of it. This project was designed to evaluate the comparative efficacy of different suturing techniques and suture material applied during end-to-end anastomosis of small intestine. The study was designed on eighteen stray dogs. The dogs were divided into 3 groups i.e group A, B, and C comprising 6 animals each. Each group was further subdivided into the subgroups as, Al, A2, Bi, B2 and Cl, C2. The dogs of group A was numbered from 1-6, group B from 7-12, and group C from 13-18 for the identification purpose. The surgery was conducted through ventral midline celiotomy from umbilicus to a variable distance caudally under general anesthesia. In group A, Simple interrupted, group B modified Gambee and in group C interrupted Lembert suturing technique for end-to-end anastomosis of small intestine was used. In subgroup Al, B, C! chromic catgut and in subgroup A2, B2 an C3 polyglyconate suture materials was used. In group Cl, operated dog No.2 died on day 16 post operatively. The versatility and comparison of the techniques were evaluated on the basis of health status including vomiting, diarrhea, and weight gain or weight loss, wound healing, radiographic assessment, decrease in lumen diameter, alignment of tissue plane and quality of wound healing of the anastomotic site in all three group A, B and C. The leakage was checked at 2, 4, 6 and 12 week post surgery using contrast radiographs. During the study period the dogs were housed in the kennels available at Surgery Section, Department of Clinical Medicine and Surgery, University of Veterinary and Animal Sciences, Lahore. The present project is clearly indicated that modified Gambee suturing technique was found to be more suitable and compatible anastomotic technique with excellent clinical superiority. It resulted in the batter wound healing, minimal lekage, minimal reduction in lumen diameter at the anastomotic site, excellent in its alignment of tissue plane, satisfactory clinical layer to layer healing , is simple to duplicate under field conditions and minimal abdominal complication.

12. Studies On Cyanide Toxicity In Ruminants

by Muhammad Avais | Prof. Dr. Muhammad Sarwar Khan | Prof. Dr. Muhammad Arif Khan.

Material type: book Book; Format: print Publisher: 2011Dissertation note: The present study was conducted with the objectives to: (a) determine the cyanogenic potential of various livestock fodder and grasses, (b) determine CN? content in blood of ruminants feeding cyanogenic plants, (c) develop a simple, reliable and inexpensive assay for the determination of CN? in blood, (d) evaluate the efficacy of various antidotes against CN? toxicity in a rabbit model, (e) find out the effect of CN? on hematological and biochemical profile, (f) study the postmortem and histopathological changes associated with CN? toxicity in various organs and (g) study alterations in tissue oxygenation and metabolic variables during acute CN? toxicity in pigs. For this purpose a total of 500 samples of various plants being used as fodder to livestock were collected from the field and analyzed for CN? content spectrophotometerically. To develop a simple picrate method for CN? estimation in blood, two goats were infused with KCN at 0.6mg/kg for 1 hours. Blood samples were collected at intervals and were subjected to the general method. Standard curve was developed using standard solutions of various concentrations of CN?. Additionally 6 rabbits were also given CN? orally for 40 days and blood samples were collected for CN? estimation. Later on, this method was successfully used to determine CN? levels from 500 blood samples of cattle, buffaloes, sheep and goats (n=125 each) feeding cyanogenic plants which were collected from the field. For antidotal studies forty two rabbits were randomly divided into seven groups viz. A, B, C, D, E, F and G each comprising of six animals. Rabbits in group A were given feed only and served as negative control, while the rabbits in group B received feed plus oral solution of potassium cyanide (KCN) and were positive control. Animals in group C were given feed, KCN and intraperitoneal (IP) injection of garlic extract. Rabbits in group D were treated with feed, KCN and IP injection of sodium thiosulfate (STS). Members in group E received feed, KCN and IP injection of both garlic extract and sodium nitrite (SNT). Animals in group F were treated with feed, KCN and IP injection of both STS and SNT whereas the rabbits in group G were given feed, KCN and hydroxocobalamin IP. The treatments were given to respective groups for a period of 40 days. At the end of 40 days, serum and fresh urine samples were drawn from each rabbit to study biochemical panel. Subsequently the rabbits were euthanized for postmortem and histopathological changes in various organs. For hematological and growth rate studies 12 rabbits were divided into two groups of six viz. A and B. Rabbits in group A were given feed only while members in group B were treated with feed and oral KCN at 3mg/kg for 40 days. The animals were weighed after every 10 days. Feed consumption rate, feed efficiency and weight gain for the members of each group were recorded. Blood samples were also collected for hematological studies at 0, 10, 20, 30 and 40 days. To study tissue oxygen and metabolic variables during acute CN? toxicity, 26 piglets were anesthetized. The non-invasive monitors were used to measured oxygen saturation, heart rate and rhythm and cerebral response to sedation. The invasive monitors were placed to measured beat to beat variability of the arterial blood pressure, pulmonary artery pressures. Mixed venous oxygen saturation (SvO2) and cardiac output were continuously monitored. Regional brain O2 (cerebral cortex) and skeletal muscle O2 saturation (rSO2) were also measured via sensors. After getting baseline metabolic and hemodynamic measurements that included arterial and venous blood gas analysis, lactates and cyanide levels, all pigs were started on an infusion of NaCN (0.55 mg/kg/hr). The infusion continued until the occurrence of sustained apnea (?3 minutes). A non-significant difference was found in the CN? content of Sorghum bicolor and S. sudanese, while a significant difference was observed between the CN? content of Jumbo grass (S. bicolor x S. Sudanese hybrid) and S. halepense. Jumbo grass and S. halepense were found to have significantly higher CN? concentrations than S. bicolor or S. Sudanese. Maize has significantly lower CN? content compared to S. bicolor, S. sudanese, Jumbo grass, or S. halepense. A gradual increase in CN? content with increasing height of plants was also observed. Highest CN? levels were observed at heights of 91-100 cm in sorghum varieties. At greater heights, a gradual decrease in CN? content was seen in all plant species, with the lowest levels at heights of 200 cm or above. No CN? was detected in maize at heights over 131 cm. In picrate method, the calibration curve was linear (R2=0.99) in the range of 0.3-120 mg CN?/L. In standard CN? solutions a color change in picrate paper from yellow to brown was observed at a concentration of 3 mg CN?/L and above. This method was sufficiently sensitive to quantify the low concentrations (0.3mg CN?/L) of CN? found in ruminant blood. In goats infused with KCN, the CN? concentration in blood was time-dependent and continued rising during infusion, gradually declining after infusion ceased after 1 h. Blood CN? levels showed a time-dependent increase in all experimental rabbits with the maximum concentration (1.34 mg/L) at day 40. The highest blood CN? concentrations were found in cattle, followed by goats and buffalo, with the lowest in sheep. When blood CN? levels of these species were compared statistically, a non-significant difference was observed. A non-significant difference was found between males and females. No relationship was observed between blood CN? levels and age of the animal for any species. Buffalo, cattle, sheep, and goats allowed to graze showed significantly higher blood CN? levels than animals kept in a stall feeding system. Animals grazing on jumbo grass were found to have significantly higher blood CN? levels than those fed S. bicolor or S. sudanese with a non-significant difference found between animals fed S. bicolor or S. sudanese. No CN? was detected in blood samples of animals fed maize. Hydroxocobalamine was found to be a significantly more effective CN? antidote than garlic, STS, SNT plus garlic extract, or SNT and STS, either alone or in combination. A combination of SNT and garlic extract was the second most effective CN? antidote. The efficacy of garlic alone was significantly higher than STS or SNT in combination with STS. The efficacy of combined SNT and STS was superior to STS alone in treating rabbits with CN? toxicity. No rabbits in any group demonstrated gross deviation from the normal organ structure. The activities of serum ALT, AST, ALP, and LDH enzymes, as well as serum bilirubin, were significantly increased in CN? treated rabbits compared to controls. Severe hepatocyte vacuolation and degeneration were present in liver of rabbits in the CN? treated group. Liver of rabbits in the control group showed normal morphological patterns. The concentrations of serum urea, uric acid and creatinine were significantly higher in CN? treated rabbits than in control group. Urinary thiocyanate levels were also significantly higher in the CN? group than in controls. Kidneys of rabbits in the CN? group demonstrated severe glomerular and tubular necrosis and congestion. Pyknotic nuclei were present in tubular epithelial cells, whereas a normal histological pattern was observed in kidneys of rabbits in control group. Serum T3 and T4 levels were significantly lower in the CN? group compared to controls. A non-significant difference in blood glucose levels was recorded between rabbits in control and CN? treated groups, and histological examination of pancreas revealed no microscopic lesions. No significant differences were observed in serum cholesterol levels of CN? and control group rabbits. The serum albumin and total protein concentration in CN? treated rabbits were significantly lower than in the control group. Heart of rabbits in both CN? and control group did not show histopathological changes under microscopic examination. The erythrocyte count, the hemoglobin concentration, packed cell volume and mean corpuscular hemoglobin were all found to be significantly lower in blood of CN? treated rabbits than control group. The mean corpuscular hemoglobin concentration was significantly higher in the CN? group rabbits than control group animals. On the other hand, the difference in leukocyte count, differential leukocyte count and platelets were non-significant. The difference in total and daily feed consumption between CN? and control group rabbits was non-significant, whereas the feed efficiency of rabbits in the control group was significantly higher than for rabbits in CN? fed group. The net weight gain of rabbits in the control group was significantly higher than in the CN? fed group. Cyanide infusion to pigs resulted in toxic levels of blood CN? accompanied by lactic acidosis. In addition, there was a progressive increase in cardiac output, Venous oxygen saturation, heart rate, elevation of central venous pressure and pulmonary artery blood pressure. Skeletal muscle rSO2 progressively and significantly decreased with increasing lactate and CN? levels. However, there was no significant change in brain rSO2.

by Uzma Farid Durrani | Dr. Muhammad Sarwar khan | Dr. Muhammad Arif khan | Factuly of veterinary science.

Material type: book Book; Format: print Publisher: 2010Dissertation note: A field and an experimental study were carried out on pet and experimental stray dogs, respectively. The objectives of these studies were to evaluate the rabies immunoprofile of dogs vaccinated with different rabies vaccines under field and experimental conditions and determine the relation between vaccine type, post vaccination intervals, health status, breed, age, gender and dewormers on rabies virus neutralizing antibody (RVNA) titer. Field study was carried out on 300 pet dogs including 1-108 months old males and females. Dogs were allocated to three groups; (I) regularly vaccinated (II) irregularly vaccinated (III) maternally immunized, each with 100 dogs bled at various stages. Experimental study was carried out on 16 adult, healthy stray dogs equally allocated to four groups; three groups for monovalent and polyvalent vaccine trials with Rabisin, Rabisyva-VP13 and Hexadog DHP-LR at day 0 and 21. Fourth group was negative control. Sample collection was carried out on day 0 and day 21 post vaccination followed by sampling at 30 days intervals till ten months, in each group. RVNA titers of the serum samples were determined by Rapid Florescent Focus Inhibition Test (RFFIT) at Rabies Lab., Kansas State University, USA. In field study 58% dogs regularly vaccinated with Rabisin, Hexadog DHP-LR and Rabisyva-VPl3 vaccines, were diagnosed with protective RV A titers while 33% dogs were suffering vaccine failure. Mean protective RVNA titers monovalent Rabisin, Rabisyva-VP13 vaccines were higher than polyvalent Hexadog DHP-LR vaccine without a significant difference. Among irregularly vaccinated dogs, only 25% dogs exhibited protective RVNA titers while 25% dogs were diagnosed with vaccine failure. 50% irregularly vaccinated dogs exhibited RVNA titer below minimum protective level. Maternal rabies immunity was minimum protective level. Maternal rabies immunity was diagnosed in 20% puppies with protective RVNA titers and 20% puppies were suffering immunity failure. Remaining samples were either diagnosed with RVNA titers below minimum protective level or dcould not be assayed due to toxic effect on BHK cells. No relation was observed among RVNA titers and vaccine type, health status and gender in any field study group while a significant relation was observed among RVNA titers, breed, age and post immunization intervals with a significant difference in all groups. In experimental study there was no case of vaccine failure in any group and all groups exhibited high protective RVNA titers at the termination of study. Both the increasing and decreasing trends were observed at various intervals of experimental study. Mean RVNA titers Were 4.53±4.23, 3.48±3.40, 9.36±7.12 in Rabisin, Hexadog DHP-LR and Rabisyva-VP13 vaccinated groups, respectively. A relation was observed among RVNA titers, vaccines and post vaccination time intervals with a significant difference. However health status, gender and use of imomodulatory levamisol were not found to be significantly affecting RVNA titers in any group. On the basis of the present study it is concluded that monovalent rabies vaccines Rabisyva-VP13 and Rabisin generate higher RVNA titers as compared to polyvalent Hexadog DHP-LR vaccine under the both field and experimental conditions however, a high incidence rate of vaccine and maternal immunity failure is one of the factors that can be responsible for high incidence of rabies especially in rabies endemic area. It is also concluded that health status, gender and immunomodulatory effect of levamisol do not significantly affect the rabies immunity however, there is the significant effect of age and post immunization intervals on rabies immunity.

15. Epidemiological, Haematological And Biochemical Risk Factors Of Parturient Haemoglobinuria In Buffaloes

by Altaf Mahmood | Prof. Dr. Muhammad Athar Khan | Prof. Dr. Muhammad Arif Khan.

Material type: book Book; Format: print ; Literary form: drama Publisher: 2011Dissertation note: Parturient haemoglobinuria is disease of economic importance which affects a considerable number of buffaloes every year in India, Pakistan and Egypt. It is a non infectious hemolytic syndrome characterized by intravascular haemolysis, hypophosphataemia, haemoglobinaemia, haemoglobinuria and anaemia. The exact pathogenesis is not known and diversified etiological factors have been associated with this disease in different parts of the continent. Information on multidimensional etiological aspects of this buffalo syndrome is quite scanty. The present study was therefore carried out in district Chakwal for assessment of disease burden (parturient haemoglobinuria), its distribution and quantification of associated epidemiological, haematological and biochemical risk factors in order to suggest control measures and future research priorities. Active surveillance was conducted in eight randomly selected villages of district Chakwal from April 2010 . March 2011. All breeding age buffaloes (1938) of these selected villages were taken as sampling frame whereas one breeding age buffalo was taken as sampling unit. Parturient haemoglobinuria appeared as number one disease among all problems of breeding age buffaloes with respect to mortality rate (1.03%) and proportional mortality rate (20%) whereas it appeared as 8th and 7th disease respectively with respect to incidence (3.97%) and case fatality (25.97%) rates. Case-Control study was conducted for quantification of epidemiological risk factors associated with disease by analyzing the data of 180 case-control pairs for various 162 hypothesized risk factors. . 7 months pregnancy, . 3 lactation number, . 60 days postpartum period, . 7 years age, previous history of haemoglobinuria and ingestion of cruciferous plants were recorded as significant (P . 0.05) risk factors with odds ratios of 15.80, 6.39, 6.23, 5.56, 3.41 and 2.51 respectively. Clinical trial was conducted on 30 haemoglobinuric buffaloes randomly divided into three groups with 10 animals in each group to compare and assess the recovery rates of three different treatment packages against parturient haemoglobinuria. The highest recovery rate (100%) was recorded for combined therapy of sodium acid phosphate and blood transfusion followed by sodium acid phosphate with antifibrinolytic drug tranexamic acid (70%) and tranexamic acid with Novacoc injection (50%). Cross-sectional epidemiological study was conducted on haemoglobinuric (n = 30) and healthy (n = 60) buffaloes for quantification of haematological and biochemical risk factors associated with parturient haemoglobinuria. Red cell count (. 5 ~ 106 /ƒÊl), haemoglobin (. 8g / dl), haematocrit . 25%, mean corpuscular volume (. 50fL), mean corpuscular haemoglobin (. 20pg) and erythrocyte sedimentation rate( . 80mm / 1st hour) were recorded as significant (P . 0.05) haematological risk factors with odds ratios of 26, 17.81, 28.95, 21, 12.25 and 26 respectively whereas billirubin unconjugated (. 0.2mg /dl), billirubin total ( . 0.3mg /dl), phosphorous (. 2.5mg /dl), molybdenum (. 70ƒÊg /dl) and selenium (. 15 ƒÊg /dl) were recorded as significant (P.0.05) biochemical risk factors with odds ratios of 26.55, 26.55, , 7.50, 11 respectively. Experimental study was conducted to determine the effect of orally administered gossypol on haematological and biochemical parameters of eight female rabbits of six 163 months age purchased from local market and maintained at university of veterinary and animal sciences from February 2011 . April 2011 under optimum conditions. The cotton seed cake containing free gossypol contents of 0.25% was fed to rabbits @ 4 grams per kg per day in addition to their routine diet including good quality fresh vegetables (cucumbers, spinach, cabbage & carrots) and clean water ad-libitum. Blood samples of each rabbit were collected after every 15 days interval and analyzed for haematological and serum biochemical parameters. Significant (P.0.05) decrease was recorded in total erythrocyte count, haemoglobin concentration, haematocrit, mean corpuscular volume and serum inorganic phosphorous whereas significant increase was recorded in mean corpuscular haemoglobin, mean corpuscular haemoglobin concentration, red cell distribution width, total leukocyte count, lymphocytes and monocytes from 0 . 60th day with the passage of time whereas non significant (P.0.05) difference was recorded with respect to granulocytes and serum calcium concentration.

16. Comparative Study Of Different Suturing Techniques For Cystotomy Closure In Canines

by Imdadullah Khan | Prof. Dr. Muhammad Arif Khan | Dr. Ayesha Hassan | Pror. Dr.

Material type: book Book; Format: print Publisher: 2012Dissertation note: The cystotomy is an incision in to the wall of urinary bladder which is commonly indicated for the removal of urinary stones and for the excision of invading tumors. Cystotomy wound is closed by varieties of suturing patterns which commonly include simple appositional and inversion types of suturing patterns. Appositional patterns are used in single-layer while double-layer appositional pattern is also used. Inversion types of suturing patterns are commonly used in double layers. Single-layer appositional patterns are commonly used in small and young animals while double-layer inverting pattern is preferred to apply in large animals. Double-layer inversion pattern has been found to decrease the size of bladder lumen when the bladder wall is thick. Bladder mucosa in all cases is not penetrated because of the danger of the formation of bladder stones. In three-layer closure mucosa is sutured as a separate layer and is indicated commonly when there is bleeding. The present project is aimed to conduct a comparative study of appositional versus inversion type of suturing patterns and two-layer versus three-layer of bladder wall repair. The study was conducted on 24 dogs divided into four groups comprising 6 dogs each. In 18 dogs experimental cystotomies were performed which were closed in following manners. Group-A: the cystotomy wound was closed in two-layer simple interrupted suturing pattern, group-B: cystotomy wound was closed in two layers by simple continuous and continuous lembert suturing pattern, group-C: the cystotomy wound was closed in three layers and group-D was the control group. These suturing techniques were evaluated for leakage with the help of contrast radiography, ultrasonography, renal function tests and physical signs. These techniques were also evaluated for their effect on residual urine volume with the help of ultrasound machine. All the suturing techniques provided water tight closure when evaluated through radiography, ultrasonography, kidney function tests and physical examination. The two-layer inversion patterns and three-layer closure techniques were found to effect residual bladder volume but the effect of three-layer closure technique was more pronounced. No crystals/stones were observed on postmortem examination of the urinary bladder in each operated dog. A well demarcated stricture was noted in dogs whose bladders were sutured in three layers. It was thus concluded form the research that appositional patterns do not affect the residual bladder volume, the catgut can be penetrated through the mucosa without endangering for cystolithiasis and the two-layer appositional suturing pattern is as effective as three-layer closure of cystotomy wound for the control of hemorrhage from the bladder mucosa.

17. Study On Different Closure Techniques Of Nephrotomy In Dogs

by Muhammad Imran | Prof. Dr. Muhammad Arif Khan | Dr. Ayesha Safdar Chaudary.

Material type: book Book; Format: print Publisher: 2012Dissertation note: Kidney is a vital organ of body. It plays an important role in whole-body homeostasis, regulating acid-base balance, electrolyte concentrations, extracellular fluid volume, and regulation of blood pressure. Kidney performs these functions in coordination of various endocrine functions; these include renin, angiotensin II, aldosterone, antidiuretic hormone, and atrial natriuretic peptide. There are different problems of the kidney like calculi lodged in the renal pelvis and neoplasia of the kidney in which nephrotomy is indicated. The project was designed to find out the most suitable technique of closing nephrotomy incision. For this purpose three groups A, B and C of dogs were arranged containing eight animals in each group. In group A after performing nephrotomy, 2/0 absorbable suture was placed through the cortex in horizontal mattress fashion and renal capsule was closed with 4/0 absorbable suture in a simple continuous fashion while in group B nephrotomy incision was apposed by applying gentle digital pressure for five minute and incision in the renal capsule was closed with 3/0 synthetic absorble suture. Whereas, in group C cut edges was apposed through tissue adhesive glue (cyanoacrylate). Physical evaluation, Urine examination i.e urine colour, Complete blood count, blood urea Nitrogen, serum creatinine and excretory urography at different intervals was carried out to evaluate the efficacy of these three techniques. The present project clearly indicated that suturless nephrotomy closure technique was found to be more suitable and compatible technique with excellent clinical superiority in terms of good weight gain, better hemostais, minimal post operative complication and maintaining kidney function.

19. Clinico-Biochemical Study After Partial And Complete Blockage Of Ureters In Dogs.

by Naveed Hussain | Prof. Dr. Muhammad Arif Khan | Prof. Dr. Muhammad Sarwae Khan.

Material type: book Book; Format: print Publisher: 2012Dissertation note: Ureteral obstruction is one of the most common problems associated with urinary system. It imparts serious consequences on the system, if not treated sharply. The present study was performed in twenty dogs after producing experimental obstruction through ureteral ligations of variable nature. The aim of the experiment was to identify the effects of variable ligations on obstructed and contralateral kidney with the help of blood parameters including hematology and serum analysis along with diagnostic imaging i.e. radiography and ultrasonography. It was noted that hematology was of least significance as diagnostic aid while serum analysis i.e. BUN and S/Cr were of some worth in early stages. As far as diagnostic imaging was concerned IV urography is considered as first line diagnosis in advanced cases revealing kidney size, parenchyma and hydronephrosis, while Ultrasonography is more sophisticated and advanced which is helpful in initial diagnosis and can study deep structures of the kidney. Results revealed that in partial obstructions, in obstructed kidneys severity of hydronephrosis and kidney damage was less than complete obstructions. In complete ureteral obstruction, deterioration of total internal structures including medulla , cortex and renal pelvis was observed. Role of contralateral kidney was also evident during the experiment, which compensated the physiological changes due to obstruction and helped the patient in returning to normal life but structural damage of variable nature was also noted depending upon the severity of obstruction in the ureter. It was observed during experiment that the revival of renal function is time dependent which is inversely related to duration of obstruction. If obstruction, mild or severe, is released earlier, recovery is quick and complete renal function restoration is possible in 24 to 48 hours of obstruction, depending upon its severity. But if delay occurs, it results in irreversible damage to the obstructed kidney and after three to six weeks no functional parenchyma is detectable in severe and mild obstructions respectively.

20. Comparative Evaluation Of Conventional Method And Staple Suture Technique For Intestinal Aanastomosis In Dogs

by Hafiz Kashif Shahzad | Prof. Dr. Muhammad Arif Khan | Dr. Aneela | Dr. Shehla Gul Bokhari.

Material type: book Book; Format: print Publisher: 2013Dissertation note: Intestinal resection and anastomosis is frequently essential during abdominal surgeries. Indications for intestinal resection are malignancy, inflammation, stricture formation, injuries and ischemia. Several surgical situations necessitate the resection of intestinal segments and the formation of consistent anastomoses. Conventionally, a large diversity of suture materials has been used to make hand-sewn anastomoses. Surgical stapler was made for the first time at the beginning of 20th century but its use remained limited in gastrointestinal surgery. Currently, stapled anastomoses is an essential part of the majority of the gastrointestinal surgeries. The simple-interrupted, single-layer, approximating technique, in which absorbable monofilament suture material is used, is presently believed to be the technique of choice for end-to-end bowel anastomosis. This procedure is mostly used in gastrointestinal surgeries with comparatively lesser complications. Intestinal anastomosis with skin staples was started by military surgeons for the soldiers suffering from bowel trauma caused by gunfire. In this technique, stainless steel skin staples were used to create a seromuscular intestinal anastomoses. There are several types of staplers available in markets, e.g. circular ligators, clip appliers, endoscopic staplers etc. The circular stapler is a disposable anastomotic instrument that places a round, double staggered row of titanium staples connecting intervening tissues. It can generate an end-to-end, end-to-side, or side-to-side anastomosis. This round stapler is available with a variety of staple line diameters to be used according to need. In current years, there has been a large shift from hand-sewn method towards the use of intestinal stapler in gastrointestinal surgery. They present a possible reduction in operational timing and are easy to learn and use than for hand-sewn method. So, staplers are very popular in the trainee. This research project was tested on 12 mongrel dogs divided randomly into two different groups (A and B). Each group comprised of 6 dogs. Conventional hand-sewn method of end-to-end anastomosis was applied on group A and stapled anastomosis was made in the dogs of group B. Two surgical techniques were applied for end to end anastomosis of jejunum. In group-A conventional hand-sewn anastomosis technique was applied. In this method a piece of jejunum was removed and then anatomosed with simple interrupted, single-layer, approximating technique. The absorbable, monofilament suture material was applied manually. This is currently considered the method of choice for end-to-end intestinal anastomosis in small animal surgery. This technique is well described and has been used throughout the canine gastrointestinal tract with a relatively low complication rate. In group-B a circular mechanical stapler was used to construct anastomosis. In this method a piece of jejunum was removed and end-to-end anatomosis was made using a mechanical stapler. Comparison of both techniques was made on the basis of clinical parameters (temperature, pulse, respiration, vomiting, diarrhea and blood in feces), radiographic evaluation, exploratory laparotomy, change in lumen diameter and duration of surgical procedure. There is a significant difference in change in diameter within each group before and after surgery but there is no significant difference in change in diameter or stenosis formation between these two groups. There is a significant difference in the duration of operation; stapled group significantly requires an average of 10 minutes less than conventional hand-sewn method. Conclusively it was inferred that there is no significant difference in change in diameter between stapled group and hand sewn group but the anastomosis construction time is shorter in stapled group. Stapled anastomosis is safe and faster technique than hand-sewn method. The prevalence of low complication rate makes it all the more ideal for application in routine practices.

21. Epidemiological, Haematological & Serological Studies Of Leptospirosis In Dogs And Human At High Risk In And Around Lahore City

by Muhammad Hassan Saleem | Prof. Dr. Muhammad Sarwar Khan | Prof. Dr. Muhammad Arif Khan.

Material type: book Book; Format: print Publisher: 2013Dissertation note: Leptospirosis is an important zoonosis of global importance capable of causing significant subclinical and clinical syndromes both in humans and animals. The disease is characterized by fever, vomiting, diarrhea, myalgia and other signs consistent with renal and hepatic disease. Considering the significance and the substantial losses rendered by Leptospirosis, the present project was designed to study epidemiology and haematology in dogs and humans at high risk in Lahore district and its peri-urban areas. The study was accomplished in 4 phases. In phase-I, sero-prevalence both in dogs and human was studied including case fatality rate and associated risk factors through cross a sectional study. For this purpose, blood samples were collected from dogs attended at the Pet Centre of University of Veterinary and Animal Sciences, Lahore and other private clinics situated in and around Lahore area through systematic random sampling technique over a period of one year (1st Dec. 2010 to 30th Nov.2011). Blood samples from every fifth un vaccinated dog were collected, but if the dog was vaccinated then the sample was collected from the next unvaccinated one. In this phase 100 sera samples from human volunteers which were at maximum risk (veterinarian, pet and livestock owners, para-vet staff) were also collected. All samples were screened out by using ELISA kits like Canine Leptospira IgG ELISA Kit Catalog no. BG-CAN11485, NovaTein Biosciences, Woburn, MA, USA and Serion Elisa Plate, Virion/Serion GmbH, Wurzburg, Germany for dogs and humans respectively at the Medicine Laboratory and University Diagnostic Laboratory, University of Veterinary and Animal Sciences, Lahore. To study overall prevalence of Leptospirosis in dogs a total of 429 dogs were examined and it was found that out of 429 blood samples 155 were found positive for Leptospira antibodies. Thus an overall prevalence of Leptospira was recorded as 36.13%. Prevalence of Leptospirosis in dogs during different months of the year was also recorded. The months of September, October and June showed ere the highest prevalence and recorded as 50%, 48.57% and 45% respectively. Although, a few cases were seen during the months of December, January and February while moderate number of cases was recorded during the rest months of the year. There was a significant difference (p<0.05) in the prevalence of Leptospirosis during the different months of the year. Out of these 429, 93 pups and 336 adults were examined for Leptospirosis and found that 26 pups and 129 adults were positive i.e. a prevalence rate of 27.95% (26/93) and 38.39% (129/336) for Leptospirosis was recorded in pups and adult dogs respectively and this difference was non-significant (p>0.05). In this study a prevalence rate of 38.49% (102/265) and 32.31% (53/164) for Leptospirosis was recorded in male and female dogs respectively and this difference between the sexes was also non-significant(p>0.05). According to the results of this study a sero-prevalence of 21.24% (24/113) in winter, 35.82% (24/63) in spring, 40.34% (71/176) in summer and 49.32% (36/73) were recorded in fall season and this difference was significant (p<0.05). The highest prevalence rate was observed in fall and summer seasons of the year during higher rain fall seasons of the year. To study overall prevalence of Leptospirosis in humans, a total of 100 blood samples were examined through random sampling technique during the whole study period and overall prevalence rate of 44.00% was observed in human population. Different risk factors like different months of the year, age, sex and season were also studied and that the highest prevalence of Leptospira in humans was observed in the months of March, April and August i.e. 66.66%, 66.66% and 60.0% respectively. No significant difference (p>0.05) in the sero-prevalence of Leptospirosis in human during the different months of the year was observed. Sex-wise prevalence rate of 48.71% (38/78) and 27.27% (06/22) for Leptospirosis was recorded in male and female respectively and this difference was significant (p<0.05). The results of this research project revealed a prevalence rate of 47.29% (35/74) and 34.61% (09/26) for Leptospirosis in adults and young ones respectively and this difference was again non-significant (p>0.05). According to the results of this study a sero-prevalence of 41.93% (13/31) in summer, 40.00% (06/15) in fall and 25.92% (07/27) in winter, while 66.66% (18/27) was recorded in spring season of the year and this difference was significant (p<0.05) and the highest prevalence rate was observed in spring. In phase-II, the effect of Leptospirosis on various blood parameters were determined in both dogs and human. The results of present study revealed a significant difference (P<0.05) between the Hemoglobin (Hb), Erythrocytic sedimentation rate (ESR), Packed cell volume (PCV), Total Leukocytic count (TLC), Neutrophils, Eosinophils and Monocytes of healthy and Leptospira affected dogs, while a non-significant difference was observed (P >0.05)among values of lymphocytes. It showed that values of Hb forthe diseased dogs were lower than healthy ones while ESR, PCV, TLC, Neutrophils, Eosinophils and Monocytes, were more than in normal dogs. Likewise, in humans all the studied parameters were significantly (P <0.05) different between infected and healthy ones. The values of Hb concentration in diseased humans were lower than the healthy ones while ESR, PCV, TLC, Neutrophils, Eosinophils, Basophils, and Monocytes were higher than in healthy people. A negligible change was observed in the percentage count of lymphocytes. In phase-III, the comparative efficacy of commercially available vaccines against Leptospira was studied. Two commercially available vaccines, Vaccine #1 with protection against two serotypes of Leptospira (Canicola, Icterohaemorragiae) and vaccine #2with protection against four serovars of Leptospira i.e Canicola, Icterohaemorrhagiae, Grippotyphosa and Pomona were compared After six months it was observed through ELISA screening that the vaccine #2 provided better overall protection compared to the vaccine #1 to the pups as well as adult dogs against the Leptospirosis but this difference was non-significant (p>0.05). In the last phase of this study the chemotherapy trial was conducted. Results found that the efficacy of Penicillin G was 70%, while in group B Amoxicillin produced 60% results and in group C Sarsaparilla proved to be 40% effective against this infection although this difference was non-significant (p>0.05). It is concluded that among therapeutic agents used to treat Leptospirosis in dogs, Penicillin G , Amoxicillin and Sarsaparilla are ranked in respective order of efficacies.

28. A Clinico - Hematological Study On Hepatic Regeneration After Variable Degrees Of Resections In Rabbits

by Muhammad Babar Saleem (2005-VA-72) | Prof. Dr. Muhammad Arif Khan | Dr. Hafsa Zaneb | Ms. Ayesha Safdar | Faculty of Veterinary Sciences.

Material type: book Book; Format: print Publisher: 2014Dissertation note: Liver is the largest visceral organ in the body and has a paramount importance. Its multi-functional abilities make it absolutely necessary for survival. It performs numerous functions in a living organism and plays its role in various physiological and biochemical regulatory processes in the body. It is also the only organ that has the capability to undergo the phenomenon of regeneration in case of cellular injury induced by chemicals or surgery. According to Craige (1948) Liver is the largest gland of the body. It is an extension of the gastro-intestinal track and connects with GIT to the common bile duct.It has two surfaces. The anterior or dorsal surface is convex while the posterior surface is concave and lies over the stomach. Liver is thickened in its dorsal portion and tappers to a thin ventral margin. The liver is incompletely divided into a right and a left liver lobe, each of which have anterior and posterior lobules. The right posterior lobule lies closely to the dorsal body wall and it accommodates right kidney in a depression called renal fossa. The gall bladder is a thin walled pouch located in a deep depression on the ventral surface of right anterior lobule. The quadrate lobe extends from the right lobe and is usually notched on its medial margin. The caudate lobe is small and well separated. The portal fissure is a large depression filled by the portal vein and it also contains some branches of hepatic artery. The liver is held in place by four ligaments namely falciform ligament, round ligament, coronary ligament and left triangular ligament. According to Borley & Achan (2005) Liver plays a key role in several regulatory processes in an organism. It is involved in various metabolic pathways comprising variable interactions with proteins, carbohydrates and fats. Liver is the main site for gluconeogenesis, converts galactose and fructose into simple sugars (glucose) and stores complex carbohydrates (glycogen).It aids in the production of different types of proteins and has a role in the formation of urea. Numerous types of fats like phospholipids, cholesterol and lipoproteins are synthesized in the liver. Liver also uses different carbohydrates and proteins to form certain fats. Liver serves as a vault for the storage of several vitamins (A, B2 and D) and iron. It helps in the complex process of coagulation by aiding in the synthesis of several important coagulation factors including prothrombin, protein C, and factors VII, IX and X.Several hormones including oestrogen, aldosterone and cortisol are metabolized in the liver. It is involved in the metabolism of a number of drugs and also has a key role in the production and excretion of bile. In fetal life, haematopoiesis is one of the key functions which is performed by liver. Liver resectioning is a technique employed for correction of numerous ailments or for the purpose of experimental study. Diseases such as tumorous growths on the liver, hepatic necrosis, cyst formation, hepatic abscess, hepatic lobe torsion and numerous others require the removal of the affected part of the liver(Martin et al. 2003; Pignon et al. 2013). The remaining liver usually recovers by regeneration through hyperplasia and hypertrophy of healthy cells of the un-affected part of the liver (Palmes and Spiegel, 2004). For experimental reasons, where different aspects of liver regeneration process are to be studied, liver resectioning technique is employed (Mao et al. 2014; Fausto et al. 2012). Numerous studies have been done to see the regeneration rate of liver in different species. In rats it has been noticed that liver can regenerate to its original size after two-third hepatectomy in only five to seven days (Mao et al. 2014).Another author states the recovery to occur in less than two weeks in rodents (Gilgenkrantz and Hortet, 2011). In humans it has been shown that resectioning up to 50 percent has resulted in complete regeneration of liver mass in only a period of two weeks (Häussinger, 2011). Rabbits being small laboratory animals with comparative ease of handling have been used extensively for research purposes. Regeneration has been studied in rabbits post chemical insult on liver or through portal branch ligations (Palmes and Spiegel, 2004). As opposed to general perception, Carpenter (2003) states that the rabbits fall under the category of rodents, they in actuality are lagomorphs. Two families composed of twelve genera and eighty-one species fall under the umbrella of order lagomorpha. They are cosmopolitan in their distribution. The main difference between rodents and lagomorphs is the presence of two pairs of upper incisors in the former group, whereas the later have only one pair of upper incisors. Despite having a great degree of similarity which these two groups share together, they are not thought to be closely associated. The animals of both the categories evolved into nine creatures separately and their similar dental patterns resulted from parallel evolution. All legomorphs consume foliage and practice caprophagy. All lagomorphs are blessed with acute tactile and olfactory senses with a considerable long-haired fluffy body coat. Lagomorphs have big side-to-side set eyes giving them a broader circular vision. Testes are in the scrotum in front of the penis. Baculum is absent in males. Females bear two to five pairs of mammary glands. Deficiency has been observed in terms of study of liver regeneration when liver resectioning is performed. The present study aims to focus on this aspect of research on soft tissue, which would enhance our understanding of liver regeneration and its rate in this specie.

29. The Effects Of Xylazin-Butorphenol And Detomidine-Butorphenol On Clinico-Biochemical Parameters During Castration in Dog

by Nadir Hussain (2006-VA-07) | Prof. Dr. Muhammad Arif Khan | Dr. Shehla Gul Bukhari | Prof. Dr. Muhammad Sarwar Khan | Faculty of Veterinary Sciences.

Material type: book Book; Format: print Publisher: 2014Dissertation note: Anesthesia is a reversible process and derived from Greek word “anaisthaesia” meaning “insensibility” and used to desensitize the whole or any part of the body. Anesthesia is classified by method of administration i.e. intramuscular, inhalational and intravenous. Injectable anesthesia includes Propofol, Diazepam, Acepromazine, Medetomidine, Xylazine and Ketamine. Anesthetic agent can be used alone or in combinations (Gonzalez et al. 2003). The purpose of Anesthesia is to produce a convenient, safe, effective, and economical means of facilitating surgical procedures while minimizing stress, pain and discomfort and adverse side effects. There are many routes of administration of anesthesia; in intravenous route, the onset of action is immediate. Peak effect is rapidly obtained, duration of action is short, and effects are more intense/ profound than other routes.Many combinations of anesthesia are in use in dogs for different surgery xylazine (0.4 mg/kg IV) combination with butorpjanol (0.2 mg/kg IV), xylazine (0.4 mg/kg IV) combination with oxymorphone (0.05mg/kg IV) , xylazine (0.4 mg/kb IV) combine with morphine (0.25mg/kg) , Medetomidine (5 to 15 ug/kg combine with butophanol (0.2 mg/kg IV), Medetomidine (5 to 15 ug/kg IV) combine with oxymorphone (o.05 mg/kg) Xylazine (0.4mg/kg) combine with Ketamine (5 to 10 mg/kg IV) acepromazine (0.05 to 0.2mg/kg IV or SQ) in combination with morphine (0.4 to 0.8mg/kg IV) and diazepam or midazolam(0.2 mg/kg IV) with hydromorphone or oxymorphone( 0.1 to 0.2 mg/kg IV) use in dog and cat (Greene 1999). Detomidine is a selective α2-adrenoceptor agonist with useful sedative, analgesic and muscle relaxation properties and is widely used as a tranquilizing or pre-anaesthetic medication in veterinary medicine But it induces cardiovascular side-effects such as hypertension, hypotension, bradycardia and dysrhythmia.detomidine. It produces prolonged and intense analgesia. Nature of the analgesic effect appears to be wide, producing a reduced response to be a secondary result of the central nervous system experimental stimulation and exhibiting a clinical effect in the horse with colic. Detomidine can be used as a safe and effective pre anaesthetic resulting in smooth induction and recovery (EL-Kammar et al. 2014). Xylazine Hcl has been widely used as a preanesthetic drug and for immobilizing dogs for diagnostic procedures (Short 1987).Xylazine is the shortest acting alpha2-adrenergic agonist..A problem with alpha2-adrenergic agonists is that they may respond suddenly to stimulation, especially to touch. The combination of opioid drugs with the alpha2-adrenergic agonists appears to reduce such sudden reactions and a synergistic effect regarding sedation and antinociception has been suggested. Additionally, all alpha2-adrenergic agonists have a dose-dependent effect on cardiovascular function. By adding an opioid drug, dose requirements of alpha2-adrenergic agonists may be reduced and cardiopulmonary function improved. The addition of opioids does not further impair cardiovascular function.The combination of xylazine and butorphanol at the doses generally used in clinical practice produces minimal and transient haemodynamic effects and no significant respiratory depression. There is no ‘blinded’ randomized crossover study regarding the xylazine sparing effects of butorphanol on sedation of horses. There are limited reports on the respiratory effects of butorphanol alone or in combination with the α2-agonist xylazine in horses, but the effects of the combination on pulmonary gas exchange have not been clarified (Ringer et al. 2012). Butorphanol is an opioid agonist-antagonist with good analgesic effects. Butorphanol is used in veterinary medicine as pain reliever and cough suppressant. It induces only mild sedation and has minimum adverse effects to the cardiovascular system. It may cause mild lowering of the heart rate and arterial pressure or slight respiratory depression. It exerts a depressive action on the respiratory system. It should not use in patient with liver disease because it cannot be eliminated and may accumulated to toxic level (Raušer and Lexmaulova, 2002).It is believed to be more effective against visceral rather than somatic pain. The antagonist property towards μ-receptors results in a ceiling analgesic effect with increasing doses. However in dogs doses between 0•2 and 0•8 mg/kg have been reported to provide visceral analgesia in vivo .Butorphanol is a dose-related respiratory depressant and causes small decreases in arterial blood pressure and heart rate (Vettorato and Bacco 2011). Castration is indicated for reproductive neutering, modification of behavior patterns, testicular neoplasia, severe testicular or scrotal trauma or injury, refractory orchitis, benign prostatic hyperplasia, perianal gland adenoma, perineal hernia, and scrotal urethrostomy in dogs. There is no specific anesthetic method for castration. Routinely castration surgery can be performed under general anesthesia or local anesthesia (Kim et al. 2004). Unlike other laboratory animals that are commonly used forresearch purpose, non-human primates and dogs are also used for research work. Their use in the biological researchrequires special considerations, regarding their care and housing, and more specifically their handling and restraining. Since non-human primates and dogs present special hazards to handlers, particularlybecause of the danger of bites and zoonotic infections (Fortman et al. 2001). Deaths due to anesthesia are lesser in dogs (1 in 601) than rabbits (1 in 72) that are the third most commonly anaesthetized pet animal in the United Kingdom (Brodbelt et al. 2005).

30. Prevalence Of Tick Borne Hemoparasites And Identification Of Ticks With Their Treatment In Dogs

by Muhammad Shehriyar Khan (2013-VA-438) | Dr. Muhammad Ijaz | Dr. Muhammad Avais | Prof. Dr. Muhammad Arif Khan.

Material type: book Book; Format: print ; Literary form: not fiction Publisher: 2015Dissertation note: Dogs are one of the most commonly owned companion pets worldwide. They are kept for various factors such as hunting, guarding, and amusement or for animal assisted therapy. Tick infestation is a common problem in dogs and its transmitted infections usually tick borne hemoparasitic diseases are emerging as a worldwide problem not just for animals but also for humans. Due to this phenomenon, ticks are now recognized as a major cause of various diseases in of urban environments. The current research has been conducted to study the prevalence of tick infestation, associated risk factors and chemotherapeutic trials of topical acaricides were used in order to study comparative efficacy, were conducted in dogs. Furthermore, prevalence of tick borne hemoparasitic diseases was also observed by performing microscopic blood smear examination in dogs of Lahore district. A total of 300 dogs (n= 200 positive for tick infestation; n= 100 negative for tick infestation) having tick infestation were included in the present study. Dogs of different sex, age and breed were selected for tick collection. The ticks were collected with the help of forceps from the target sites of each dog, while adopting all necessary measures to avoid damage to the mouth parts of the ticks and skin of the host. The collected ticks were preserved in plastic containers containing 70% ethanol, which was separate for each specimen. Ticks were identified under stereoscope by observing morphological characteristics of each tick, according to the key. Blood sample for tick borne hemoparasitic diseases was drawn from cephalic vein of each dog using disposable syringe and was poured into EDTA vacutainer. Thin blood smear slide was then prepared from the blood of the animal, dried in air and was stained using Geimsa’s staining method. The hemoparasites observed in the blood of the dogs were then characterized and Summary 51 identified by their morphological characteristics. For chemotherapy, a total of 30 tick infested dogs of different breeds viz. Rottweiler, German shepherd and Labrador was used in therapeutic trials. Each breed of dog was divided into 2 subgroups which were then treated with topical ivermectin and fipronil 1500μg/kg b.w and 15mg/kg b.w respectively. Efficacy of the drugs was then measured on the basis of disappearance of clinical signs and reversal of tick infestation at day 2, 4 and 6 of post-medication. Data regarding the prevalence of tick borne hemoparasitic diseases and tick infestation was analyzed by using Non-parametric, Chi-square test whereas data on therapeutic trials was analyzed by Z-test, using statistical package for social science (SPSS). P < 0.05 was considered significant. The results obtained showed us that the study area is at a risk of tick infestation and tick borne hemoparasitic diseases. In dogs, Rhipicephalus sanguineus (brown dog tick) species was observed and identified as a major tick infesting dogs of the study area during the course of study. Various determinants including tick density and its genus, host age, sex, predilection site host breed and season significantly affected the tick infestation in the study area. The prevalence for tick infestation was found highest in Pastoral dogs as compared to other breed types found in dogs. Among breeds German shepherd showed highest prevalence for tick infestation. Adolescence age group among dogs was more prone to tick infestation. The number of males affected by ticks was highest as compared to females in dog population. Among the dog population, majority of the animals infested by ticks were categorized under mild infestation. The most favorable predilection site for tick infestation in dogs was ear pinnae, followed by head and then neck. Monsoon was the most favorable season for tick infestation in dogs. September was found to be highest favorable month for tick infestation in dogs. Summary 52 In tick borne hemoparasitic diseases, babesiosis was the highest prevalent disease in dogs (63.33%), followed by trypanosomiasis (0.66%) and mixed infection (0.33%). Age group among dogs showed non-significant factor affecting prevalence for TBHD’s. The number of affected dogs for babesiosis was greater in adolescence age group as compared to other age groups. On the other hand, trypanosomiasis and mixed infection adult age group was found highly susceptible. Males of canine group were slightly more susceptible than females in case of babesiosis. Similarly for trypanosoniasis and mixed infection males were more prone than females. For babesiosis, monsoon was the most favorable season in dogs. Whereas for trypanosomiasis and mixed infection, post monsoon was found to be favorable season in dogs. In breed type of dogs, prevalence for babesiosis was found highest in Pastoral dogs. In dogs the prevalence for babesiosis was found highest in German shepherd breed, whereas for trypanosomiasis and mixed infection Cross breed was the most susceptible breed. For trypanosomiasis and mixed infection Cross breed was the most susceptible breed type. The prevalence for babesiosis was found highest in the month of September. For trypanosomiasis and mixed infection, the month of October was found to be highest susceptible month for dogs. Chemotherapeutic trial of topical acaricides against tick infestation in dogs revealed that Fipronil was more efficacious drug as compared to Ivermectin. Such type of epidemiological data of tick infestation, TBHDs and its chemotherapeutic trial will help to control tick infestation and tick borne hemoparasitic diseases to save the life of companion animal.

by Muhammad Essa Kakar (2005-va-229) | Prof. Dr. Muhammad Arif Khan | Prof. Dr. Kamran Ashraf | Prof. Dr. Muhammad Sarwar Khan | Prof. Dr. Muhammad Azam Kakar.

Material type: book Book; Literary form: not fiction Publisher: 2015Dissertation note: Babesiosis which is also called as piroplasmosisis, Texas fever, redwater or tick fever, is an emerging, tick-transmitted (by a vector ixodidea) disease caused by intraerythrocytic parasites of the genus babesia having considerable worldwide economic, medical, and veterinary impact. Keeping in view the importance of babesiosis under local conditions, the present study was designed to evaluate the status babesiosis in Balochistan. For this purpose field and experimental studies were carried in two districts Quetta and Sibi of Balochistan Province to find out the status of babesiosis in Bhag Nari, Holstein Friesian and Crossbred cattle. During field study epidemiological status of babesiosis was highlighted by selecting 600 cattle randomly from each district. The animals were distributed into 2 major groups i.e. Young animals less than 12 months and adult over 12 months of age. These groups were further sub-divided into Young animals (less than 6 months, up to 9 months and up to 12 months) while Adults animals (up to 2 years, 3 years and over 3 years). The vector of babesia was also kept under keen observation for the prevalence/infestation rate, identification and economic losses caused during the course of study. Blood samples were collected from each animal and processed for blood smears examination and PCR for further confirmation of babesia infection. The blood samples were also processed for hematological study to evaluate the effect of babesiosis on different blood parameters. For experimental study 148 animals were selected through clinical signs of babesiosis, blood smear examination and PCR. Out of theses 40 animals were maintained for therapeutic trail to find out the cheapest and easily available drug against bovine babesiosis. For this purpose Neem leaves were used in decoction form while Imidocarb dipopionate was kept as standard control. The Summary 177 results of epidemiological study revealed higher prevalence of babesiosis (20.5%) in district Quetta while 15.16% was recorded in District Sibi. Similarly higher prevalence was recorded in Holstein Friesian than in Crossbred and Bhag Nari cattle respectively in both districts Quetta and Sibi. Furthermore higher prevalence of babesiosis was recorded in adult groups of Holstein Friesian than in Crossbred and Bhag Nari cattle. Similarly season wise higher prevalence of babesia infection was noticed in summer followed by spring, autumn and winter respectively while higher prevalence was noted in female group of animals than male animals. Blood smears examination and PCR confirmed two babesia species i.e. babesia bigemina and babesia bovis. Similarly Boophilus tick species were identified as the vector of babesia parasites. During present study mixed hemoprotozaon infection of babesia mixed with theileria was recorded in both districts. The results of conventional method and modern diagnostic technique (PCR) revealed that PCR identified higher babesia infection during the entire 4 seasons as well as in all age groups whereas blood smears examination was capable to diagnose babesiosis in adult groups during the months of summer and spring season. Breed wise prevalence was also higher in samples treated with PCR than blood smears examination and even samples that were declared negative by blood smears examination were also found positive. The results of complete blood cell count from blood samples of infected experimental animal showed regenerative, macrocytic hypochromic anemia. Blood smear examination showed presence of many babesia with reticulocytes. Abnormalities in erythrocyte structure were seen. The result of blood parameters of total erythrocyte count, total leukocyte count, packed cell volume and hemoglobin showed significant decrease in all three affected Bhag Nari, Holstein Friesian and Cross bred cattle. The values of MCV and MCH were increased and MCHC was slightly less than normal value. No efficacy of neem decoction was noted against bovine babesiosis.

33. Comparative Efficacy Of Chemical And Surgical Debridement For Management Of Proud Flesh In Equines

by Assad Moon (2008-VA-187) | Prof. Dr. Muhammad Arif Khan | Dr. Shahla Gul Bukhari | Dr. Muhammad Ijaz.

Material type: book Book; Literary form: not fiction Publisher: 2015Dissertation note: Wound healing in equines is one of the most laborious and expensive challenge to all stud farmers and surgeons. Exuberant granulation typically is an irregular and unhealthy appearing tissue with many grooves and clefts. Histologically exuberant granulation tissue has remains of fibrin deposits, which have not been cleared by the acute inflammatory response. Horses are predisposed to trauma wounds that can be labour intensive and expensive to manage. Wounds localized at the trunk region are less problematic and heal faster than wounds located at the distal aspect of the limb. Complications such as wound infection, formation of exuberant granulation tissue (EGT) and hypertrophic scarring are frequent. The EGT or “Proud Flesh” is considered similar to the keloid of the human skin and together with wound contamination/infection, is currently the most complicated aspect of wound management in equines. The present project was designed to evaluate comparative efficacy of surgical and chemical debridement of such kind of wounds in horses. The clinical study was conducted on 20 already traumatized horses of either sex. The animals were divided into four groups (I, II, III and IV) comprising five animals each. These animals were kept in S.P.C.A, University of Veterinary and Animal Sciences, Lahore. In a group I, Surgical excision was carried out to remove excessive growth from wounded area. Local anaesthesia with two percent lignocaine was in filtered for removal. Antiseptics were applied and over-granulation was smoothly removed from one margin of skin to other. Group II animals were treated with ten percent copper sulphate ointment, Group III animals were treated with two percent silver nitrate ointment and Group IV animals were treated with white lotion. Each technique had its own advantages and disadvantages. The results proved that surgical removal was a best choice for management of hyper-granulated wounds. It also had good scar formation SUMMARY 72 and faster recovery as compared to other chemical agents. It allows the closure of large wounds and faster epithelization to margins. The results of present study clearly indicated that surgical excision of hyper-granulated wound on early stages yields good recovery and proper union. Although silver nitrate has better penetrating power in wounds but it has no ability to epithelize the wound which terminates in slow recovery. Moreover silver is an expensive and less affordable to a common man. Copper sulphate has good recovery but it causes irritation while application and animal feels pain. White lotion is one of the good choice but expensive. Availability: Items available for loan: UVAS Library [Call number: 2413-T] (1).

34. Clinico-Epidemiological And Experimental Observations On Feline Lower Urinary Tract Disease Among Domesticated Cats

by Abeera Naureen (2007-VA-541) | Prof. Dr. Muhammad Sarwar Khan | Prof. Dr. Muhammad Arif Khan | Prof. Dr. Azhar Maqbool.

Material type: book Book; Literary form: not fiction Publisher: 2015Dissertation note: Idiopathic Feline Lower Urinary Tract Disease (iFLUTD) has been known as a major as well as important problem throughout the world especially the veterinary profession. Nicks of this problem also found in Pakistan, however the veterinarians are usually unable to properly diagnose this disease due to lack of knowledge as well as the ancillary diagnostic equipment availability for this disease. Present study was divided into two phases. Phase – 1 included clinico-epidemiological data. To this end, target of more than 502 domesticated client-owned cats of either sex, age, breed, etc showing signs of feline lower urinary tract disease (FLUTD) as per Buffington (1994) were examined accordingly from 3 different cities (Lahore, Faisalabad, and Islamabad) of Pakistan). All data collected was based on a predesigned proforma by using structured interview of the owners. Diagnosis was solely based on serum-cortisol levels, urinalysis, radiography and ultrasonography. Phase II involved experimental trial. The data obtained from whole of the study was then presented in tabulated form as frequencies and percentages. Treatment and outcome of the disease were also analyzed accordingly. According to the present study conducted it is proved that iFLUTD is present among the cats in Pakistan. Its proper cognizance among the Pakistani veterinarians is still non-existent and is misdiagnosed as colic or constipation issues in cats. The present study was undertaken to bring iFLUTD into the reportive of small animal practitioners working in Pakistan. The present study debunked various previous notions like iFLUTD is associated with commercial diets and canned foods only if we talk about this region majority of cases were noticed that had home-cooked food given by the owner. Moreover, cases in Siamese breed are larger than Persian breed. It has been strongly associated with Indoor housing management. Additional work is still needed to explore untouched areas of epidemiology including factors other than those being studied in the previous literature. Academicians in veterinary pathology and veterinary medicine of Pakistani universities should embrace this malady in the Doctor of Veterinary Medicine (DVM) curricula. According to the present study results it is concluded that two factors like stress and pain accelerate the sympathetic nervous system outflow compared to normal felines leading to the inflammatory response. Thus the stress factor must be reduced in the form of making hiding places for cats at home to reduced down the fear factor along with enhancing the feeling of owes for that particular place. Moreover, some more practices should be performed by the owner to reduce down the stress factor like playing with the pet, giving full attention, placing toys and other attractive things like yarn balls at the feline places (where they live/placed). There was no significant difference found between the groups based on the food with health score along with the therapeutic judgment. Hence, it is recommended that more experiments should be performed on larger scale to assess GAG therapy on increased number of felines and need of hour is to conduct more veterinary studies to get information and authenticity for its use against iFLUTD. From this study conducted, I recommend to the owners that the cats must be provided with the indoor hiding places and play with their pets in order to reduce the stress factor that increases the risk of idiopathic lower urinary tract disease. Moreover, the trend of home-cooked diet should be reduced along with increase in water intake by the cat. Availability: Items available for loan: UVAS Library [Call number: 2420-T] (1).

35. Sedative And Analgesic Effects Of Xylazine, Ketamine And Diazepam In Ducks

by Hafiz Manzoor Ahmad (2013-VA-856) | Dr. Hamad Bin Rashid | Prof. Dr. Muhammad Arif Khan | Dr. Asim Khalid Mahmood.

Material type: book Book Publisher: 2015Dissertation note: Mostly of the drugs given intramuscularly are ineffective in producing anesthesia in ducks. There are some combinations which have a synergistic effect for producing good sedation and analgesia. This combination includes ketamine-xylazine and ketamine-xylazine-diazepam. This study was conducted on ducks which are divided into two groups (A, B). The group A was given xylazine (5 mg/kg) and ketamine hydrochloride (15 mg/kg) and the birds of group B was given ketamine hydrochloride (15 mg/kg), xylazine (2.5 mg/kg) and diazepam (2.5mg/kg) cocktail. Anesthesia is the desensitization of body through nerve blockage. It is the reversible state of analgesia and loss of responsive-ness, loss of skeletal muscle reflexes, decreased stress response, or all of these simultaneously. The average body temperature of ducks treated with KX and KXD was 105.02±0.12, and 104.97±0.18 oF, respectively. The average heart rate of ducks anesthetized by KX and KXD was 103.75±3.18, and 98.63±2.24 beats/min, respectively. The average respiratory rate of ducks treated with KX and KXD was 19.2±1.62, and 16.11±0.52 breaths/min, respectively. The onset of sedation in ducks anesthetized by KX, and KXD was recorded in 2.11±0.75 and 1.14±0.04 minutes after drug administration. The duration of sedation in the ducks anesthetized was 87.33±6.74, and 127.42±18.60 minutes, respectively. The recovery of ducks from sedation was recorded in 89.53±6.22, and 128.56±18.52 minutes. Onset of analgesia in ducks anesthetized by KX and KXD was recorded in3.22±0.54, and 1.67±0.77 minutes after drug administration. The duration of analgesia in the ducks anesthetized with KX and KXD was 39.76±3.89 and 81.15±11.17 minutes, respectively. The recovery of ducks from analgesia was recorded in 43.37±4.42 and 82.82±11.15 minutes, when anesthetized with KX and KXD respectively. The onset of sedation, onset of analgesia, duration was relatively delayed in KX SUMMARY 36 group; recovery from sedation and analgesia was observed in ducks anesthetized with KX group is early than KXD group. These effects can be obtained from a combination of drugs to achieve very specific combinations of results. The purpose of this study is to evaluate the sedative and analgesic effects of xylazine- ketamine and diazepam in different combinations.

36. Comparative Efficacy Of Polypropylene And Polyester Mesh For The Repair Of Abdominal Wall Defect In Pigeons

by Muhammad Naveed Ali (2007-VA-114) | Dr. Hamad Bin Rashid | Prof. Dr. Muhammad Arif Khan | Dr. Asim Khalid Mahmood.

Material type: book Book; Literary form: not fiction Publisher: 2016Dissertation note: Polypropylene is a widely used biomaterial for the treatment of ventral abdominal wall hernias. It exhibit pain, prominent inflammatory response and foreign body reaction. Polyester (Polyethylene terephthalate) is hydrophilic material works with body’s natural systems to improve tissue integration while reducing negative foreign material response. Polyester offers extremely lower pain intensity and less foreign body reaction. The purpose of designated research was to compare the efficacy of polypropylene and polyester meshes for the treatment of abdominal defect. Both are non-absorbable meshes. Polypropylene mesh is available in Pakistan with the trade name of Prolene® (Ethicon,Johnson & Johnson, USA). Polyester mesh is not available inPakistan and was acquired from Al Zahrawi Medical, a local healthcare company in Dubai, United Arab Emirates. Polyester mesh is available with brandname of (Parietex®, Covidien, France). The experimental study was conducted on 16 (sixteen) healthy pigeons presented for massive abdominal defect repair. All birds were thoroughly examined to rule out any other anomaly before study. The birds were allocated into two different groups, viz. Group A and Group B with 8 birds in each group respectively. All treatments were administered intramuscularly using 1 ml insulin syringe. The Polypropylene mesh (Prolene®, Ethicon) was used for the treatment of abdominal repair for group A. The birds of group B was treated with Polyester mesh (Parietex®, Covidien). Ventral abdominal wall repair was performed in both groups using Polypropylene and Polyester mesh respectively. The surgery was performed at Surgery Section, Department of CMS, UVAS, Lahore for 3 months duration (including adaptation and postoperative period). Both meshes were compared on the basis of postoperative complications (wound healing, pain evaluation, hematoma, seroma and abscess formation), inflammatory responses and adhesion formation after application of mesh fixation. During experiment, it was observed that polypropylene mesh resulted in a prominent pain sensation, persistent inflammatory reaction, proliferating fibroblast, more granulating tissue, macrophages appearance, increased connective tissue thickness and proliferating collagen fibre. It was observed that Polyester mesh resulted in less pain sensation, no foreign body reaction, no neutrophil appearance and rare granulating tissue. Polyester mesh showed remarkable advantages over polypropylene mesh in terms lower pain level, reduced size seroma and extremely less scar tissue formation. Based upon all the findings it was concluded that polyester mesh is safer and more effective in terms of post-operative complications and outcomes.

38. Comparison Of Suturing And Sutureless Techniques For Gastrotomy Closure In Canines

by Muhammad Atif (2007-VA-133) | Dr. Naveed Hussain | Prof. Dr. Muhammad Arif Khan | Dr. Jawaria Ali Khan.

Material type: book Book; Literary form: not fiction Publisher: 2016Dissertation note: Gastrotomy is suggested in case of gastric dilatation with volvolus, gastric foreign bodies, gastric retention, out flow obstruction, hypertropicgastropathy, gastric neoplasia, and gastroduodenal ulceration. Gastrotomy closure technique after gastric surgery is very crucial to avoid post-operative complication like peritonitis. Different techniques are considered to close gastric incisions like absorbable suturing material, stapler suture and use of adhesive glue. These techniques give different kind of effects on gastrotomy closure. The present study was carried out on 12 adult mongrel dogs with an average of 15 to 20 kg body weight. They were divided into three groups, each group having 4 animals and designated as group A, B and C. Standard Gastrotomy procedure was performed in group A B and C. After performing surgery, the dogs of group A were sutured by cushing suture, followed by continuous lambert suture by 2/0 synthetic absorbable suture. While in group B dogs, stapler sutures were used to close gastric incision and in dogs of group C, incision site was closed through use of tissue adhesive glue (cyanoacrylate). Comparison of all suturing and sutureless techniques was carried out through Physical evaluation, food, water intake and defecation, Weight loss / gain, Complete Blood Count, Leakage evaluation by contrast radiography and postmortem findings. It was concluded that suturing technique (using absorbable suture material in two layers) maybe considered much better than other two methods (adhesive glue and stapling) economically, due to use of ease and least post-operative complication. Although glue may be considered as second option due to easy handling, minimum fibrosis, least stenosis and better healing time. Stapling may be the third one SUMMARY 55 because it experiences difficulty to fire, greater chances of infection due to staples and more prone to leakage and stenosis. The results of this study will help veterinarian, field workers and pet practioners to use suturing technique as most effective and appropriate technique for gastrotomy closure in terms of better healing, less blood loss and least chances of post operation complications.

39. Study On The Repair Of Long Oblique Mid-Shaft Femoral Fracture In Domestic Fowl, Using Full Cerclage Wires With Or Without Intra-Medullary Pin

by Muhammad Waqas (2008-VA-224) | Prof. Dr. Muhammad Arif Khan | Dr. Hammad Bin Rashid | Prof. Dr. Aneela Zameer Durrani.

Material type: book Book; Literary form: not fiction Publisher: 2016Dissertation note: Fracture is a challenging problem in domestic as well as wild birds. Caged birds are prone to stress and self-injury. Wing and leg fractures in birds are most common problems. The fracture of bones is common in avian species as a result of impact injuries due to collision with branches, electric lines or other obstacles, either natural or anthropogenic. The basic principles of fracture fixation are the same in birds and mammals. Fractures treated with biomechanically sound fixation and proper attention to soft tissues will be most likely to heal with a functional outcome. However, osteomyelitis, bone sequestration, and joint ankylosis still continue to be major factors in inhibiting healing and bone functionality. This research project was designed with the aim to test the effectiveness and accuracy of three sets of bone splintage devices in healing long oblique mid-shaft femoral fractures in birds, with minimal side effects and stress to the patient. The Study was conducted on 12 adult, domestic fowls of either sex. The birds were received as clinical cases presented with long oblique femoral fracture at Pet Centre, University of Veterinary & Animal Sciences Lahore. They were individually marked with coloured plastic rings for the sake of identification. They were divided into three groups i.e. Group A , Group B and Group C comprising four birds each, which were designated as I, II, III, and IV respectively. In the birds of Group A long oblique femoral fracture was reduced and immobilized with intramedullary pinning, with pin size between 2.5mm to 3.0mm. While in Group B, similar fracture was treated with 2 – 3 full cerclage wiring. And in the final Group C both of the above techniques were applied simultaneously i.e. IM pin with 2 – 3 cerclage wires. The birds were maintained in separate cages post-operatively until the completion of the study. Subsequent comparative parameters were studied which included physical examination of wound, lameness grading, radiological scoring for callus formation, fracture line union, SUMMARY 74 fracture alignment as well as callus remodelling. The collected data regarding study parameters was illustrated by descriptive statistics and non-parametric analysis of variance (Kruskal Walis Test) using IBM SPSS Statistics version 20. Conclusion: Therefore, as advocated by the results of this study, intramedullary pinning (preferably threaded) with at least 2 – 3 full cerclage wiring was a better choice for the correction of a long oblique mid-shaft femoral fracture in domestic fowl. The combination of both these techniques together give a strong backbone for bone healing to take place with minimum amount of stress to the bone fragments. Both these techniques were easy, required little soft tissue manipulation, were cost-effective, required less equipment and could easily be applied by an average practitioner.

by Mir Ahmad Khan (2005-VA-214) | Prof. Dr. Muhammad Arif Khan | Prof. Dr. Muhammad Azam Kakar | Prof. Dr. Muhammad Sarwar Khan | Prof. Dr. Aftab Ahmad Anjum.

Material type: book Book; Literary form: not fiction Publisher: 2016Dissertation note: The present study was conducted to investigate the prevalence of Ovine and Caprine Theileriosis in Northern Highlands and Suleiman Mountain Region of Balochistan, Six thickly populated /union councils were included in the study area. Samples were collected from 2870 animals Sheep (n= 2200) and Goats (n= 670) for screening of the disease. The samples were collected and processed in Regional Disease Investigation Laboratories, Department of Livestock and Dairy Development Balochistan, T.B. Sanatorium Hospital Quetta and Center for Vaccinology, Bacteriology, The University of Balochistan, Quetta and Medicine Laboratory, Department of Clinical Medicine and Surgery, The University of Veterinary and Animal Sciences, Lahore. Data revealed 20.82% disease in sheep and 9.70%. in goats. The regional prevalence of theileriosis revealed 19.19% in Northern Highlands and 17.48% in Suleiman Mountain Region Chi-square analysis showed significant difference in the prevalence of disease in sheep and goats. The regional difference was not significantly different between two regions of Northern Balochistan. The comparison among union councils showed significant difference being highest prevalence (22.71%) in union council Kuchlak district Quetta followed by Aghberg (18.42%) and Hanna Urak (15.53%) in Northern highlands and Union Council Zangiwal Jogezai (19.83%) followed by Kach Amaqzai (16.30%) and Sinjavi (15.92%) in SMR. The disease prevalence when compared among 4 different breeds of sheep showed significant difference being highest in Karakul breed (34.62%) followed by Shinwari (24.54%), Bibrik (19.36%) and Harnai (16.40%). The highest prevalence of theileriosis in sheep and goats were observed in Summer season (30.30%) followed by Autumn 19.07%, Spring 14.52% and Winter SUMMERY 105 7.61%. Chi-square analysis of the data showed significant difference in the prevalence of the disease in different seasons of the year. The disease was also compared in three age groups of sheep and goats. The data showed 22.17% disease in adult animal group above 2 years of age followed by 15.85% in animals between 1-2 year and 7.99% in age group below one year. Statistically significant difference in all age groups was found in chi-square analysis. The sex wise prevalence of theileriosis revealed non-significant difference between male and female sheep and goats. Two different species of Theileria were reported by many researchers causing disease in sheep and goats. The PCR was carried out for the identification of Theileria species affecting sheep and goats in Balochistan. Two species specific sets of primers were designed using 18SRNA gene sequence to identify these two species of Theileria and the distribution among the two species of animals. The genomic DNA of two species of parasite was successfully amplified in positive samples. The assay was proved successful and we recommend for the prevalence surveys for theileriosis in sheep and goats. The data showed that the prevalence of T. lestoquardi was 73.80% in sheep and 69.23% was in goats in the target regions. It was found the T. lestoquardi was highly prevalent and causing theileriosis in small ruminants. The prevalence of T. ovis was 26.19% in sheep and 30.76% in goats respectively in the investigated animals; it was less than T. lestoquardi. It was concluded that both Theileria species were identified and found circulating in small ruminants in the target region of Balochistan. In the study we determined that PCR method based on 18S RNA gene could detect and differentiate T. ovis and T. lestoquardi. Effect of theileriosis in sheep and goats on hemeto-biochemical parameters were studied included RBCs, Hb%, PCV, Platelets, WBCs, MCV, MCHC, AST, ALT, BUN, Bilirubin and Creatinine. Blood samples were collected from Theileria confirmed, diseased animals (sheep and SUMMERY 106 goats) along with equal number of healthy animals for comparison. In sheep RBCs, Hb%, PCV, WBCs, MCHC, AST, ALT and Creatinine values showed significant difference when compared with values of healthy animals. Significant (p<0.05) reduction was noted in measurement of RBCs, Hb%, PCV and MCHC whereas, AST, ALT and Creatinine showed significant increase in diseased animals. In goats affected with theileriosis showed significant decrease in RBCs count and Hb%. The values for AST, ALT and Creatinine were found significantly increased in diseased animals when compared with healthy control group of equal number of animals. In present study it was noted that Butalex intra muscularly at the rate of 2.5 mg/kg body weight is quite effective in eliminating the Theileria parasite from the blood of sheep and goats and treatment at the day 10 post treatment. Imizol was also found an effective treatment of theileriosis but less effective than Butalex. Availability: Items available for loan: UVAS Library [Call number: 2690-T] (1).

by Muhammad Asad Islam (2012-VA-576) | Dr. Sadaf Aslam | Prof. Dr. Muhammad Arif Khan | Prof. Dr. Muhammad Sarwar Khan.

Material type: book Book; Literary form: not fiction Publisher: 2015Dissertation note: Ophthalmic procedures can be performed by many clinicians in horses using local nerve blocks by using local anaesthetics for short duration of action for completion of these procedures. These surgical procedures may involve exclusion of third eyelid, suturing of laceration around eye orbit and tumor which can be caused due to any reason with in time period of thirty minutes. Inner chamber centesis can be done easily by using the above mentioned technique in standing horse. There are numerous benefits of doing standing surgical methods and avoiding general anaesthesia in horses. As hospitalizing horse may get other infectious diseases from surroundings like colitis and laminitis and also injured it when recovering from general anaesthesia. On the other hand standing surgical procedure reduced such complication by using local anaesthetic for short duration. Bupivacaine Hcl gave an ideal local eye anaesthesia compare to xylocaine Hcl for standing surgical procedures in horses. The present study was accomplished to assess the effectiveness of two local eye anaesthetics; xylocaine Hcl and bupivacaine Hcl by two different techniques i.e. retrobulbar technique and auriculopalpebral technique in horses. A total of 12 horses from indoor clinic and S.P.C.A were used in this study. These horses were subjected to two groups’ i.e. Group A and B. Each of these groups was further subdivided into two subgroups i.e. Group AI, AII and BI, BII respectively. SUMMARY 42 Horses in group A were administered xylocaine Hcl through auriculopalpebral technique and retrobulbar technique. While horses of subgroup AI were given xylocaine Hcl by auriculopalpebral technique and horses in subgroup AII were injected xylocaine Hcl by retrobulbar technique. Likewise horses in subgroup BI were given bupivacaine Hcl by auriculopalpebral technique, while those of subgroup BII were given bupivacaine Hcl through retrobulbar technique. The efficacy of above mentioned local anaesthetics was compared on the basis of Pattern of induction, Duration of anaesthesia and Recovery Pattern. Presence or absence of reflexes was also noted i.e. Pupillary Light Reflex and Blink reflex. The data were analyzed through one way analysis of variance (ANOVA). The difference in group’s means was determined by Least Significant Difference (LSD) post-hoc test. A probability level of (P<0.05) was considered as statistically significantly difference. The statistical analysis was performed using statistical package for social science (SPSS) version16. Availability: Items available for loan: UVAS Library [Call number: 2679-T] (1).

43. Comparative Efficacy Of Ketamine-Xylazine-Tramadol Combination With Ketamine-Xylazine-Ketorolac Tromethamine In Dogs

by Ameer Hamza Rabbani (2009-VA-58) | Dr. Hamad Bin Rashid | Prof. Dr. Muhammad Arif Khan | Dr. Mamoona Chaudhry.

Material type: book Book; Literary form: not fiction Publisher: 2017Dissertation note: The study was designed on the premise that use of Ketamine-Xylazine-Tramadol combination was more efficacious in providing better depth of anesthesia and postoperative analgesia than the combination of Ketamine-Xylazine-Ketorolac tromethamine. Two separate combinations of anesthetic cocktails i.e. ketamine-xylazine-tramadol and ketamine-xylazine-Ketorolac tromethamine were tested for their comparative efficacies. A total of 8 mongrel adult clinically healthy male dogs between 1 to 2 years of age which were presented to clinic for castration, were managed in to two groups comprising 4 (n=4) individuals in each. These groups were designated as group A and B. General and clinical examination of the animal, LFT and RFT were performed prior to surgery. Atropine was administered at dose rate of 0.04mg/kg SC twenty minutes prior to the surgery. Both anesthetic regiments were used respectively in either groups and their efficacy was tested based upon the depth of anesthesia and postoperative analgesia. In case of group A ketamine was used at a dose rate of 6mg/kg, xylazine at 0.5mg/kg and tramadol at a dose rate of 2mg/kg. These anesthetic agents were administered intramuscularly. The time it took for onset of sedation and depth of anesthesia was monitored, while presence of ocular, oropharyngeal, and anal sphincter reflexes indicated induction, depth, maintenance and recovery from sedation. In case of group B, ketamine was used at a dose rate of 6mg/kg, xylazine at 0.5mg/kg and ketorolac tromethamine at a dose rate of 0.5mg/kg. These anesthetic agents were administered intramuscularly. The time it took for onset of sedation and depth of anesthesia were monitored, while presence of ocular, oropharyngeal, and anal sphincter reflexes indicated induction, depth, maintenance and recovery from sedation. Surgical procedure for castration was SUMMARY 58 performed as surgical plane of anesthesia was acquired. Postoperatively, Intramuscular antibiotics were injected for 5 days to avoid secondary bacterial infections to wounds. Cleaning of the wound with good antiseptic solution and excellent hygienic measures were adopted to minimize infection. Balanced diet was given to improve health of animals. LFT and RFT were performed preoperatively (baseline), and one hour postoperatively in each dog. The measurements were analyzed as change from baseline in each dog. The results were statistically analyzed using t-test with significant level 0.05% (p≤0.05), using statistical analysis software Statistica. The results of temperature, pulse and respiration were statistically analyzed using t-test with significant level 0.05% (p≤0.05). Observations pertaining to depth and quality of sedation were analyzed by using t-test with statistical analysis software Statistica. Statistical significance was assigned at p≤0.05. This study was helpful in determining efficacy of tramadol an opioid against ketorolac tromethamine which is an NSAID. This study emphasized upon discovering the most efficacious adjuvant to anesthetic combination of ketamine and xylazine. This study aimed to reduce the dose of xylazine without compromising the anesthetic effect of the combination while mitigating its side effects as well. This study provided us with a viable analgesic agent which may be administered peri-operatively to provide analgesia during immediate post-surgery period. Furthermore magnitude of improvement in depth of anesthesia helped determine an effective and cheap adjuvant to ketamine-xylazine combination.

45. Treatment Of Long Oblique Tibial Fracture With Intramedullary Pin Alone And Full Cerclage Wires In Cats

by Syed Muhammad Faheem Ahmed (2010-VA-147) | Dr. Ayesha Safdar | Prof. Dr. Muhammad Arif Khan | Dr. Muhammad Zahid Tahir.

Material type: book Book; Literary form: not fiction Publisher: 2017Dissertation note: Fracture of long bone in animals is a challenging problem these days. Leg fractures in cats are quite common problem. Fractures treated with biomechanically sound fixation and proper attention to soft tissues will be most likely to heal with a functional outcome. However, osteomyelitis, bone sequestration, and joint ankylosis still continue to be major factors in inhibiting healing and bone functionality. This research project was designed with the aim to test the effectiveness and accuracy of three sets of bone splintage devices in healing long oblique mid-shaft tibial fractures in cats, with minimal side effects and stress to the patient. For the study total twelve adult cats as and when presented at Pet Centre, University of Veterinary & Animal Sciences Lahore, and Saleem Veterinary Clinic and petshop Lahore, having long oblique fracture of tibia irrespective of breed, sex and considering almost similar age group, both stray and domesticated were selected. These cats were divided into three groups i.e groups A, B and C comprising of four cats in each group, and designated as 1, 2 3 and 4 respectively. They were admitted as clinical trial patients and were kept in separate cat cages at Saleem Veterinary Clinic until the completion of the study. Specific tagged collars were applied on all the cats. They were kept under comfortable environment and on a standard commercially available cat feed diet with ad labitum access to water. All the cats of three groups, having long oblique tibial fracture were treated with 3 separate techniques for comparison. In group A, fracture was reduced and immobilized with intramedullary pinning. In group B, fracture was treated with full cerclage wires alone while cats of group C were treated with intramedullary pin and cerclage wires. Thus comparative fracture healing and efficacy of individual techniques in their respective cases were evaluated. Subsequent comparative parameters were studied which included physical examination of wound, lameness grading, radiological scoring for callus formation, fracture line union, fracture alignment as well as callus remodelling. The collected data regarding study parameters were illustrated by descriptive statistics and non-parametric analysis of variance (Kruskal Walis Test) using IBM SPSS Statistics version 20. Conclusion: Therefore, as advocated by the results of this study, intramedullary pinning (preferably threaded) with at least 2 - 3 full cerclage wiring was a better choice for the correction of a long oblique mid-shaft tibial fracture in cats. The combination of both these techniques together give a strong backbone for bone healing to take place with minimum amount of stress to the bone fragments and also to counteract different forces acting on the fracture site.Both these techniques were easy, required little soft tissue manipulation, were cost-effective, required less equipment and could easily be applied by an average practitioner.

46. Comparative Efficacy Of Advanced Surgical Hemostats In Rabbit Spleen

by Maheen Shafeeq (2010-VA-102) | Prof. Dr. Muhammad Arif Khan | Dr. Hamad Bin Rashid | Dr. Muti-ur-Rehman.

Material type: book Book; Literary form: not fiction Publisher: 2017Dissertation note: The spleen is delicate organ which is at high risk of damage after blunt trauma to the abdomen. Splenic accidents such as spleen rupture and splenic hemangiosarcoma, are most common cause of intra-abdominal hemorrhage in dogs. When an incision is given on spleen there is always a high risk of bleeding. In severe cases animal often leads to death due to massive blood loss and hypovolemic shock. The objective of study was to check the efficacy of latest and advanced surgical hemostats i.e., Surgicel Original and Surgicel Snow to control bleeding when spleen is severed either accidentally or surgically. These hemostats are affordable, safe, reliable and convenient. For this, Rabbits were arranged in three groups. Group A consisted of 4 Rabbits on which Surgical Gauz was used. In Group B Surgicel Original was used. On rabbits of Group C Surgicel Snow was used. Hemostasis time of all the groups was monitored and number of leucocytes, erythrocytes, platelets AST, ALT and ALP were evaluated. The results of present study clearly indicated that Surgicel Snow is better choice to control hemorrhage than Surgicel Original. Therefore, when ligation and other conventional methods of controlling blood stand impractical, Surgicel should be used to control arterial, venous and capillaries bleeding during surgery. Conclusions On the basis of findings of this study, it has been concluded that Surgicel Snow is better hemostat than Surgical Original. Surgicel Snow yields ideal stoppage of hemorrhage and does not impair vital function of spleen. Availability: Items available for loan: UVAS Library [Call number: 2945-T] (1).

47. A Study On Postural Sway In Horses During Different Sedation Protocols Along With Clinico-Biochemical Evaluation In Clinical Cases

by Hamad Bin Rashid (92-AG-676) | Prof. Dr. Muhammad Sarwar Khan | Prof. Dr. Muhammad Arif Khan | Prof. Dr. Muhammad Ashraf.

Material type: book Book; Literary form: not fiction Publisher: 2017Dissertation note: 6.1. Observational study of postural sway using accelerometer in horses sedated with different sedative combinations Balance is the ability to maintain center of gravity by a body within the base of support, whereas the phenomenon of continuous movement and improvement of the position of the center of gravity within the base of support is referred to as postural sway. Most of the living creatures including man, horse and other animals need to maintain their postural balance for their daily requirements, as most of them are either bipeds or quadrupeds. To attain this balance, co-ordination between sensory system, skeletal muscle system and the central nervous system is required. These systems are responsible for the pattern of walk in the horses, which is called as gait. Any abnormality in the nervous system results in an altered gait, which if assessed properly is a useful tool in diagnosing many ailments & disorders of the locomotor system. To assess these changes in the gait pattern, many methods have evolved over the years. The gait can be assessed by Kinematic or Kinetic Analysis. An accelerometer is a detecting element that measures acceleration. Accelerometers can measure: vibrations, shocks, tilt, impacts and motion of an object. An accelerometer by itself is only a sensing element, in order for it to be useful the sensor needs to be combined with other elements such as, power, logic, memory and a means to translate the output. An acceleration recorder incorporates all of these elements into one package. There is a measurable difference in postural sway at stance between different sedation protocols. This study aims to document and quantify the postural sway of horses undergoing various sedation protocols, with the aim of identifying a sedation protocol that will reduce sway and improve the ease with which standing non-painful diagnostic imaging procedures (Radiography, Scintigraphy and MRI) can be carried out. The present study assessed the postural sway during sedation in horses and evaluated a sedation protocol with minimal sway in horses. Equine surgery depends heavily on various imaging procedures. Diagnostic imaging plays important roles-first, in diagnosing and localising a disease process; second, in assessing the surgical intervention to be applied; and third, in the follow-up evaluation of the patient. Many imaging techniques like Radiography, Ultrasonography, Scintigraphy, Magnetic Resonance Imaging and Computed Tomography are used at veterinary hospitals and clinics, the world over. In order to achieve good results for these diagnostic modalities, various drugs and their combinations have been used by scientists to achieve good standing sedation in horses (e.g., Acepromazine, Butorphanol, Detomidine, Ketamine, Romifidine, Xylazine, etc.). The reason for integrating sedations which use combinations with Ketamine in this study and its different effect on the musculature i.e. increasing the muscle tone, while the alpha2-agonists (Romifidine, Detomidine, Xylazine), all reduced the muscle tone. Potentially, increasing the muscle tone of a horse will reduce the sway, as the constant correction of postural position with reduced muscle tone may be avoided. Horses that are In-Patients and Out-Patients brought to the Large Animal Hospital, Dept. of Vet. Clinical Studies, EBVC, RDSVS, UoE, UK, and have the medical need for diagnostic imaging procedures, and that require sedation so that these procedures can be carried out safely, were included in the study. The measurements were recorded pre-sedation and post-sedation while the horse is being imaged. The horses were observed during Radiography, Ultrasonography, Scintigraphy and Magnetic Resonance Imaging, or some other minor/major surgical intervention, under the influence of standing sedation. The body sway was measured using a MicroStrain G-link wireless triaxial accelerometer. It was secured on the skin above the midline of the sacrum with adhesive tape. Both sway episodes as well as continuous postural adaptations was assessed from the sum vector of the three acceleration traces. The results of current study showed no significant difference (p>0.05) in the mean values of postural sway between different drug groups. All drug combinations produced sedation in standing horses. However, pre-sedation mean values were significantly different from post-sedation mean values of postural sway. This shows that the subjects which were administered different combinations of sedatives exhibited variation in the postural control over time that is the readings of accelerometer either increased or decreased after sedation when compared to baseline (pre-sedation) values. The findings of current investigation also revealed a significant combined effect of drug groups and measurement time. Which means that the horses within groups, administered with different sedative combinations showed a change in postural sway values measured by accelerometer over time and these mean values either increased or decreased post-sedation. However, Post hoc Tukey’s test could not establish a significant difference (p<0.05) in the multiple comparision tests. Although post-sedation mean values of postural sway of group 2 (romifidine alone) and group 7 (detomidine alone) were different from pre-sedation values (p<0.1). The mean values of accelerometer for group 1 (detomidine+butorphenol) and group 4 (xylazine alone) were decreased from pre-sedation values that means the horses in these groups were more stable and had better control over their stance when compared with pre-sedation values. In the current study, the mean values of accelerometer for group 2 (romifidine alone) and group 7 (detomidine alone) were increased from pre-sedation values that means the horses in these groups were less stable and had poor control over their stance. This showed that detomidine alone with a dose range of 3 to 9 μg/kg is insufficient for standing procedures. Availability: Items available for loan: UVAS Library [Call number: 2970-T] (1).
