Publisher: 2010Dissertation note: The Indigestion and lactic acidosis are most common non infectious managmental problem in small ruminants that have been causing global concern as a potential threat. Some cases shows the clinical signs very early while some shows late clinical signs most of which arc common among these two diseases. So it is a matter of priority to develop quick and efficient methods for differential diagnosis and quick response of the therapeutical agent.
It was found that rectal temperature, Ruminal fluid pH, and ruminal movements decreased significantly in Indigestion and lactic acidosis in sheep and goats before the treatment in comparison to the control group. On the other hand it was observed that pulse and respiration rate were increased in both groups D-l and D-2 as compare to control group. In present study design, 2 groups of animals were designed for Indigestion and lactic acidosis (I for each disease). Each group was divided into 4 sub group each comprising 10 animals (sheep and goats). The group 1-1 of D-l was provided with Acetic Acid Vinegar 500-800 ml per animal per oral while 1-2 of D-l group was treated with Stomach powder @ 50-70 grams per animal per oral. Similarly sub group LA-l of D-2 was treated with sodium bicarbonate 5% 200-3 00 ml per animal intravenously and sub group LA-2 of D-2 group was provided with sodium bicarbonate @ 40-60 grams per animal per oral. On the other hand sub group 1-3 of D-l and LA-3 of D-2 was kept as diseased untreated control and subgroup 1-4 of indigestion group and LA-4 of Lactic acidotic group was kept as healthy control. Mean values obtained after treatment for D- I group (Indigestion) were rectal temperature increases more significantly in I-I than that of 1-2 while pulse rate of 1-2 sub group was significant than I-i. Respiration rate change was also significant in I- I sub group. Blood pH of 1-2 was significant while ruminal fluid p11 increases more significantly in 1-1. On the other hand mean values obtained allcr treatment for D-2 group (Lactic acidosis) were rectal temperature and pulse rate changed significantly in LA-i sub group. Respiration rate change was significant in LA-2 sub group Blood pit of LA-i & LA-2 in similar range while ruminal fluid pH increases more significantly in LA-I that LA-2 sub group.
Ruminal protozoa were not seen in ruminal fluid of both groups. Ruminal movements was rarely observed in indigestion group and not observed in lactic acidotic glol'').

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.

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.

Publisher: 2011Dissertation note: The dog's stomach is a sac-like structure designed to store large volumes of food and begin the digestive process. Where the stomach empties into the duodenum, there is a circular valve-like muscle called the pyloric sphincter. The stomach can be divided into cardia, fundus, body, antrum, and pylorus. Gastric glands provide all the secretions.The stomach wall is made up of different layers, which are (from lumen outwards). The mucosa, the submucosa, two layers of muscularis, with an outer longitudinal and an inner circular layer the serosa.
Nonspecific, self-resolving acute gastritis or gastroenteritis is the most common GI disease seen in small animals. Congenital pyloric stenosis caused by congenital muscular hypertrophy also leads to pyloric outflow Obstruction. Acquired pyloric stenosis may be the result of external compression of the pylorus, caused, for example, by a pancreatic or hepatic tumor. Pyloric obstruction is common in humans and dogs. The only conclusive diagnostic test for pyloric stenosis is a satisfactory response to surgery, Ramstedt's pyloromyotomy being the simple and safest procedure. Various surgical procedure have been described for the relief of pyloric stenosis. Pyloroplasty (Heinekemukulicz procedure) , Y-U pyloroplasty, gasttroduodenostomy, gastrojejunostomy , and the procedures including the various bypass operations.
In the view of above the present study was designed to evaluate the efficacy of Biliroth I, Biliroth II, and Roux-en-y resection procedure as a treatment of pyloric stenosis in dogs with special emphasis on the effectiveness of procedures used in the terms of physical evaluation, healing of wound, radiography, and postmortem studies. Twenty four mongrel dogs were selected and divided into four groups comprising six animals each.
In group A, group B, and group C, Biliroth I, biliroth II, and roux-en-y resection procedures were used respectively. Group D was kept as a control group.
The operations were conducted in aseptic condition. The stomach was exposed through the celiotomy incision to proceed the three surgical procedures in dogs of group A, group B, and group C. The incision was closed in routine manner. Clinical evaluation was performed to evaluate the efficacy of the techniques and postmortem was performed to see the gross changes in the stomach and abdomen cavity of dog. The results of this study suggested that all the three procedures are effective roux-en-Y resection procedure was more effective and useful. Although Roux-en-Y resection procedure is more difficult procedure to perform but it is more effective than Biliroth - I and Billroth - II procedures regarding clinical evaluation (vomiting, diarrhea, healing of wound) delayed gastric emptying time and least postoperative complications and postmortem studies.

Publisher: 2011Dissertation note: The present project had been designed to study the effect of heat stress on cattle calves and to evaluate the efficacy of electrolytes solution (Normal Saline and Ringer Lactate) on various blood parameters. Five groups of calves comprising 10 in each group were selected for experimental study. Group A: Affected calves with heat stress were provided shade after taking TPR and the effect of shade were checked after one hour. Group B: Heat stressed calves of same age group were given Normal Saline IV according to their body weight and the effect were checked through TPR, hematology and blood electrolyte. Group C: Heat stressed calves of same age group were given Ringer's Lactate IV according to their body weight and the effect were checked through TPR, hematology and blood electrolyte. Group D: calves of same age group affected with heat stress were taken as the positive control. Group E: calves of same age group were normal healthy calves (negative control). Temperature was taken at regular intervals of one hour daily. Respiration was observed by placing the hand in front of nostrils. Heart rate was observed by stethoscope daily in morning and evening. The blood sample of each calf was collected both for control and experimental animals through disposable syringe from jugular vein. The blood was shifted to University Diagnostic laboratory, University of Veterinary and Animal Sciences Lahore. The samples were taken before and after therapeutic trials. Blood samples were taken for blood electrolyte examination and hematology. Serum of the blood was separated by centrifugation for electrolytes measurements. The flame photometer was utilized to measure the serum sodium (Na+) potassium (K+) Chloride (Cl+) and Bicarbonate (HCO3) concentration. The physical sign of experimental group before cooling were noted .sever sweating and panting were observed under physical sign. The pulse rate, respiration and rectal temperature of experimental group before cooling were increased. Changes found in CBC and blood electrolytes like sodium, potassium, chloride and bicarbonate were measure by flam photometry.
These all observation showed that the animal of experimental group before cooling were suffering from electrolyte imbalance ,but it was not so serious which may result in death of the animal, however the persistence of that condition might result in heat stroke which is often lethal.
It is concluded that serum electrolyte concentration, CBC and pulse rate, respiration and rectal temperature help in accessing the condition of animal suffering form the heat stress. From the present study it can be concluded that heat stress cause changes in biochemical and Hematological parameters in calves. These changes can be overcome by giving animal's fluid therapy and by providing good shade in hot summer. Further studied are required to Conducted on other species of animals to understand the effect of heat stress .Other biochemical and hematological parameters should be studied in bovine calves and other animals for the better understanding the effects of heat stress.

Publisher: 2011Dissertation note: Cryptosporidiosis is one of the important parasitic diseases of dogs and other canine and feline species which is of special concern with reference to the immuno-compromised individuals. Several trials have been run to estimate the prevalence and treatment of the said disease in different regions of the globe, in immuno-competent and in immuno-compromised patients as well.
The aim of this study was not only to determine the prevalence of Cryptosporidiosis in pet dogs in the Lahore district but to evaluate the comparative efficacy of Azithromycin, Clindamycin, Tylosine and combination of Clindamycin and Tylosine as well. For this purpose, in first phase of the trial, oocyst enumeration was performed in 300 samples collected from three different clinics in Lahore district. The prevalence was found to be 21.33%. In the second phase, 32 Cryptosporidiosis positive dogs were selected and were randomly divided into four equal groups. These four groups of dogs were given afore-mentioned dosages of the above mentioned drugs and oocyst count was done on d 7, d 14 and d 21.
The results revealed that Azithromycin proved itself as the most successful drug in elimination of Cryptosporidium in dogs as it showed 79.26% efficacy as compared to the combination of Clindamycin and Tylosine (43.58%), Clindamycin (26.53%) and Tylosine (16.03%). It should be stated that the future trials may manipulate the dose rates and the period of therapy to achieve even better results. The efficacy results for the combination of Clindamycin and Tylosine also suggested a positive innovation in its regimen in future studies. And last but not least, the efficacy percentages of Clindamycin and Tylosine (as individual drugs) demonstrated them poor drugs to be used against Cryptosporidiosis specifically in dogs atleast in context of the dosage regimens and therapeutic periods employed in the current study.

Publisher: 2012Dissertation note: The study was conducted in District Swat, Khyber Pukhtoonkhwa province, to study the percentage of carrier buffaloes of hemorrhagic septicemia in the region and Immune status of buffaloes. Tracheal swabs and blood were collected from 200 buffaloes slaughtered at Saidu Sharif slaughter house. The selected buffaloes were divided into four age groups, the first group had animals of two and less than two years of age, the second had animals with age of three years, the third group, five years and fourth group had animals with age of more than five years. Tracheal swabs were cultured for the isolation of Pasteurella multocida, for identification of carrier animals and blood sample were processed to determine the antibodies titer of buffaloes against Pasteurella multocida.
The results showed that 8 (4%) out of total 200 examined buffaloes were identified as carriers of hemorrhagic septicemia by isolating the Pasteurella multocida from their tracheal swab. Out of 8 carrier buffaloes 4 were from group IV, 3 from Group III and 3 from group II. The percentage of carrier buffaloes in four age groups was 0%, 2%, 6% and 8% in group-I, group-II, group-III and group-IV respectively, showed that percentage of carrier buffaloes were high in group IV while lowest in group I. The Pathogenicity tests of the all 8 isolates showed that they were pathogenic to mice and cause their death within 24 hours of incubation.
Serological study of blood sample for antibodies titer showed that out of 200 buffaloes 156 (78%) showed antibodies titer ?1:16 which were considered immune against hemorrhagic septicemia. Out of 156, 17 were from group-I, 46 from group-II, 46 group-III and 47 from group-IV. Percentage of immune buffaloes in different age groups was 34%, 92%, 92% and 94% in group-I, group-II, group-III and group-IV respectively. The higher number of immune animals i:e 94% were in group-IV and the lowest were in group-I i:e 34%.
Results showed that all the carrier buffaloes had antibodies titer more than 1:16. The antibodies titer of the 4 carrier buffaloes were 64, 2 had 128 while 1, 1 had antibodies titer 16 and 32 respectively.

Publisher: 2012Dissertation note: Sheep and goats sustain an expensive profitable and environmental position in Asian agriculture (Devendra 1996). Majority of the livestock owners earn their income through sale of additional animals and their by-products. There are several factors affecting the production potential of livestock. Among these, parasitic infestations are prevalent, affecting different livestock species all over the world. Parasitic infestation especially ecto-parasites are the major veterinary problems in most of the developing and under developed countries of the world. The physical condition and production in animals is severely affected by tick and mite infestation. It is one of the most common problem of sheep characterized by anemia, poor physical condition, decreased milk quality and poor meat production.. The present study was conducted on ticks and mites to study their prevalence, their effect on various blood parameters and to evaluate the efficacy of Ivermectin and Azadirchta indica (neem oil) on sheep in and around Lahore, Pakistan.
In this study 300 sheep suspected for tick and mite infestation on the basis of clinical signs were collected from outdoor hospital of University of Veterinary and Animal Sciences Lahore, Outreach hospital Sitar wala and Civil Veterinary Hospital Thokar Niaz Biag. The tick sample were collected with the help of foreceps and mites sample through skin scraping. Out of this 300, 198 samples were collected from outdoor hospital UVAS Lahore, from which 84 were positive with prevalence of 42.42% for tick and mite infestation, and 62 samples were collected from outreach hospital Sitarwala from which 24 were positive giving prevalence of 38.70% and 40 samples were collected from CVH Thokar Niaz Biag, out of which 17 samples were positive with prevalence of 42.5%. All the collected samples were processed at medicine laboratory, UVAS, Lhr.
Whereas in the third part therapeutic trials on 20 sheep (n=15 tick and mite infested and n=5 healthy sheep) was done and divided into four groups A, B, C&D. Each group was comprised of 5 sheep .In group A, the infested sheep were treated with two doses of ivermectin 0.2mg/kgS/C 7 days apart, on 7th day its efficacy was 40%and on 14th day it gave 100% efficacy. In group B the infested sheep were treated with neem oil (Azadirachta indica) @1 table spoon, its efficacy was 20% on 7th day and on 14th its gave 40% efficacy, in group C infested sheep were kept as positive control, whereas healthy sheep were included in group D.
In the second part of present project haematological studies on 10 sheep (n=5 tick and mite infested sheep, n=5 healthy sheep) were performed to see the effect of tick and mite infestation on various blood parameters (Hb, PCV,TLC) and it was fsound that Hb and PCV values were decreased whereas TLC was increased in infested sheep.
The therapeutic trials of this study concluded that the Ivermectin was most effective drug against ticks and mites in sheep.

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: ; Format:

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.

Pakistan is gifted with a large population of small ruminant including 58.3 and 27.4 million heads of goats and sheep respectively 2010.According to Livestock Census 2006, there were about 92164 sheep and 221912 goats' populations in Bannu district. Sheeps and goats are playing a leading role in the national economy by producing wool, skin, meat, milk and farm yard manure. Fasciolosis, parasitic gastrioenteritis, hydatidosis, coccidiosis, ectoparasitism, theleriosis and babesiosis are the major parasitic problems of small ruminants .There was an urgent need to carry out research on applied aspect leading control of parasites.
Study Objectives: The main objectives of the present study were;
(i) To have an overview on the overall prevalence of ectoparasites and endoparasites in small ruminants throughout the district by means of fecal tests.
(ii) To observe the affect of ecto and endoparasites on blood profile of the infected individuals.
Hypothesis: It was hypothesized that
¢ Parasitic diseases are highly prevalent in sheep and goat in District Bannu..
¢ External and internal parasites have significant effect on blood parameters.
Methodology and Results
During this study period 500 sheep and 500 goats were examined for endo and ectoparasites while using various fecal tests such as using direct microscopic examination, simple test tube flotation method and sedimentation method for endoparasites. Out of 500 goats and 500 sheep, 47 goats and 63 sheep were found positive for ectoparasites and percentage ratio was 9.4% in goats and 12.6% in sheep. Mostly, three types of ectoparasites were observed in both of cases i.e. goats and sheep (ticks, lice and mites). The total no. of positive cases found for ectoparasites in goats were 244 (ticks 10.2%, lice 30.4% and mites 8.2% in district Bannu). This result indicates a significant load of ectoparasites in this area of the country. Out of 149 positive cases of ecto-parasites in sheep; tick infection was 7.8% (39/500), lice 15.2% (76/500) and mite infection was 6.8% (34/500). Fecal samples of all 1000 animals were analyzed for the presence of endoparasites, out of which 90.6% goats and 87.4% sheep were found positive for endoparasites. Overall goats were more likely to be positive for Haemonchus Spp. and almost 50.2% (251/500) animals were found positive. The prevalence of other endo-parasites like Trichurus 5.6% (28/500), Strongyloid 4% (20/500), Coccidia 8.6% (43/500), Fasciola 12% (60/500) and Trichostrongyloide were 10.2% (51/500) while in case of sheep Haemonchus Spp. positivity was 33.2% (166/500). The prevalence of other Endo-parasites like Trichurus 6.8% (34/500), Strongyloid 2.4% (12/500), Coccidia 6.8% (34/500), Fasciola 10.6% (53/500) and Trichostrongyloide were 13.6% (68/500). The hematological profile of infected animals indicates high TLC and low hemoglobin level.
Conclusion
It is concluded that high prevalence was due to poor management and lack of knowledge about feeding, vaccination, hygienic conditions and lack of proper deworming programme. To overcome the problem it was necessary to educate the farmers about deworming programme and proper use of insecticides.

Publisher: 2013Dissertation note: The background of this study is that world health organization (WHO) reports that neurological disorders affect one billion people worldwide, including 50 million affected by epilepsy. Epilepsy is a common neurological disorder characterized by recurrent, periodic, spontaneous and unprovoked seizures. Childhood absence epilepsy (CAE) is an autosomal dominant disorder and a heterogeneous familial condition in which family members express absence seizures initially, and then show multiple phenotypes of myoclonic epilepsy including partial or absence seizures and generalized tonic conic seizures. Molecular genetics techniques have identified various CAE associated mutations in many genes i.e. ion channels (CACNA1H, CACNA1G, CACNA1N), sodium channel genes (SCN2A, SCN1A, and SCN1B) and some GABA receptor genes (GABRG2 and GABRD). CACNA1H ion channels are the principal intermediaries of fast neurotransmission in the CNS and have been frequently reported to play a significant role in a number of seizures. CACNA1H gene encodes the alpha (?) subunit and is usually located in post synaptic.
Various parameters are used in the present study was aimed to investigate coding regions of CACNA1H gene for analyzing the mutations involved in epilepsy. Blood samples of unrelated true representative of CAE were collected from psychiatry departments of different hospitals of Lahore. DNA were extracted with the standard protocol and amplifications of the CACNA1H regions were done with specially designed primers.
Later on, analysis of the results is done by sequencing of target fragments is carried out. Sequences are analyzed through BioEdit software and then aligned with the help of clustalW2 software.
It has been identified by the recent study on the absence epileptic patients of Pakistan that the gene CACNA1h has SNPs in the exon 9 and 10 at the position (2025G>A) and (4867 G>T) respectively which eventually alters the protein, making it hyperactive as the mutations are in the sensor regions of the protein, thus giving a 'gain in function' property to the ion channel.
In the conclusion, we must say that further study, with much larger sample number, is required to revise the effects of this polymorphism and accurately identifying the associated factors. There is a need to explore the other gene mutations causing epilepsy in local population of Punjab and Pakistan that will ultimately help to develop genetic counseling strategies, gene therapies and prenatal diagnostic procedures for the population of Pakistan.

Publisher: 2013Dissertation note: Cystic hydatid disease has a worldwide distribution. Echinococcusis cause great economic loses in Pakistan and lead to the loss of worth 276.20$ per 100 sheep and goats, as well as 165.72$ per 100 infected buffaloes, cattle and camels. It has zoonotic importance and also have well-recognized zoonosis in Pakistan and numerous cases have been reported in the medical literature. Cystic hydatid disease is caused by Echinococcus granulosus, (E. granulosus), tapeworms. Adult tapeworms of this specie are small in size. Their measurement revealed that they reach upto 2-11 mm in length and contain protoscolex, the cephalic end for attchment and 2-5 proglottids segments. Two rows of keratinized hooks and four number of suckers are present on scolex. The last gravid proglottids segments bear the large number of fertilized eggs, which are shed after every 7-14 days. Eggs are oval in shape, having clearly distinct oncophore and 30-36 micrometer in diameter. There are several different strains of E. granulosus, which are genetically distinct. These strains vary phenotypically and therefore, this feature can be used for the control of this parasite. 10 genotypes of E. granulosus are identified up till now. Therefore, in this study we used PCR technique for prevalence determination and molecular characterization of specific strain of E. granulosus. The primers specific for E. granulosus were used in this study. The E.g.ss1for (5¡Ç-GTA TTT TGT AAA GTT GTT CTA-3¡Ç) worked as forward primer, while E.g.ss1rev (5¡Ç-CTA AAT CAC ATC ATC TTA CAA T-3¡Ç) worked as reverse primer. For this purpose, total 200 numbers of cyst samples (100 from each district) were collected from liver and lungs of cattle, buffaloes, goats and sheep slaughtered at different private and public abattoirs in Okara and Jhang. An antimortem examination was performed on each animal
LIV
and data regarding each animal entered in data capturing form before slaughter. Whole cyst sample was collected without rupturing and preserved in ice packs. Then these isolates were transferred to laboratory and stored at -20 ¢ªC for further processing. For the genetic analysis of E. granuous (Hydatid cyst) DNA was extracted from germinal layer and cystic fluid by using DNA extraction reagent (TRIREAGENT¢ç, Molecular Research Center, Ohio, USA) according to the manufacturer.s instructions. PCR was carried out by using primers specific for G1 strain of E. granulosus. The whole three steps (Denaturation, Anealing, Amplification) of PCR was carried out in PCR thermo cycler under conditions specific for E. granulosus. The final PCR product was electrophoresed in a 1% agarose gel containing 0.5 ug/ml of ethedium bromide. Electrophoresis was completed by applying 90 volts for 40 min. After required time, gel was placed in UV trans-illuminator to visualize the band shown by specific genotype of E. granulosus. Specific bands at 254 bp confirmed the G1 strain of E. granulosus. Results indicated the prevalence of 37% in Okara and 65% in Jhang district of Punjab. While in cattle (58.00%), buffalo (76.00%), sheep (36.00%) and goats (34.00%) prevalence was observed. As well as, (44.7%) prevalence of E. granulosus was calculated in liver and (54.8%) was observed in lungs in both districts. So, this study predicted the prevalence of hydatid cystic disease in ruminants in Okara and Jhang. PCR technique was used for the diagnosis of hydatid cyst in animals. This molecular characterization technique enables us to know the specific strain of E. granulous existing in these two districts. Finally the data gathered from this study help to understand the disease structure and to develop future plan.

Publisher: 2013Dissertation note: The present project was designed to study the presence and importance of
M. pachyderma infection in otitis externa in domestic dogs and to compare the efficacy of clotrimazole and nystatin, in district Lahore, Pakistan as no such previous reference is available. Random samples were collected for a period of three months, from the Government and private pet clinics. The targeted population was pet dogs of different age, sex and breeds. Samples were collected from all the dogs suffering from otitis externa brought to the clinics. The positive animals for M. pachyderma were divided into two groups, i.e. A and B, and treated with clotrimazole and nystatin respectively. A total of 200 cases of otitis externa were recorded and a prevalence of 23% of otitis externa with M. pachyderma infection were found positive.
In the present study, a non-significant difference (P>0.05) was observed between pendulous ear and erected ear dogs and no sex predilection was observed (P>0.05). However, a higher prevelance (86.90%) was recorded in dogs more than one years of age group. In the present investigation, clotrimazole showed higher efficacy (P < 0.05) with the significant reduction of yeast population and clinical signs of otitis.

Publisher: 2013Dissertation note: Toxoplasmosis is a parasitic zoonosis with worldwide distribution caused by Toxoplasma gondii and is demonstrated in domestic livestock, wild life, other animals and humans. Keeping in view the zoonotic importance of the disease, the current study was conducted to find out the epidemiological status of toxoplasmosis in camels and human population in Cholistan desert area of Bahawalpur and to determine the possibility of transmission of toxoplasmosis from camels to their owners.
Serum samples from camels (n=226) and humans (n=113 camel owners and n=113 people having no contact with camels) were collected and analyzed by using Latex Agglutination Test (LAT) to determine the prevalence of Toxoplasma gondii in camels and humans.
Overall 9.73% camels were seropositive for anti-toxoplasma antibodies. In the month of April camels had the high prevalence of 11.5% (9 out of 78). . The highest prevalence (12%) was determined in the camels having age of 11 years or above. The prevalence of toxoplasmosis was high in the third trimester of pregnancy (27.2%). Although, the difference in prevalence of T. gondii infection was significantly different (P<0.05) at pregnancy of she camel. Overall 27 (12%) humans were seropositive for anti-toxoplasma antibodies. The highest prevalence of toxoplasmosis (15.25%) was detected in the people in 30-40 years or above age group. The highest sero-positivity was observed in camel owners (15.92%) and the lowest sero-positivity (7.96%) was observed in the people having no contact with camels. However, the difference in prevalence of T. gondii infection was significantly different (P<0.05) at the contact of humans with the camels.

Publisher: 2013Dissertation note: Prolene (Polypropylene) is a gold standard for repairing ventral or incisional hernias but exhibits increased inflammatory responses as a non-absorbable foreign material and causing post-operative complications. Prolene composite mesh has a reduced polypropylene concentration in addition to an equal proportion of absorbable material. Hence they provide more tissue in-growth and less inflammatory response and minimal adhesion formation.
The present project was designed to compare the two mesh implants viz., the simple non-absorbable poly-propylene (prolene) mesh and the prolene-vicryl composite mesh which is comprised of an outer latticework of the non-absorbable polypropylene, in addition to absorbable polyglactin 910 (vicryl) on the inner side. Both mesh implants are readily available in Pakistan; the non-absorbable polypropylene mesh is available in Pakistan with the Trade name of Prolene® (Ethicon, Johnson & Johnson, USA), while the prolene-vicryl composite mesh is available with the Trade name of Vypro® (Ethicon, Johnson & Johnson, USA). Both meshes were compared on the basis of post-surgical complications (Pain evaluation, wound healing, hematoma, seroma and abscess formation), inflammatory responses mesh shrinkage and adhesion formation after application of hernioplasty implant.
The experimental study was conducted on 12 (twelve) healthy mongrel dogs to compare prolene and prolene-vicryl composite mesh for ventral or incisional hernia repair in dogs. The dogs were randomly selected as either male or female, aged between one to two years (mean age 1.5 years). The body weight of the experimental animals was in the range between 16-20 kg (mean weight 18 kg). The dogs were housed in kennels at Pet Centre of University of Veterinary and Animal Sciences, Lahore for a period of 3 months (including adaptation and post-operative period). The dogs were divided into three groups (A, B & C) comprising of 4 dogs in each group; and they were numbered from # 1-4 in Group A, #5-8 dogs in Group B, and #9-12 dogs in Group C, for proper identification and for ease of research. The respective meshes were used for ventral or incisional hernia repair in group A and group B dogs, while group C dogs served as control group.
The groups were surgically treated as follows:
Group A (Prolene mesh)
Group B (Prolene-vicryl composite mesh)
Group C (Control group)
During experimental trials, it was seen that polypropylene mesh resulted in a persistent inflammatory response, prominent foreign body reaction, rare vascularization, more fibroblast more granulating tissue, increased thickness of connective tissue, and extensive collagen fiber. In comparison, the polypropylene-vicryl composite mesh resulted in better vascularization, rare inflammatory response, moderate collagen fiber formation, smooth incorporation of collagen fibers into the mesh, low foreign body reaction, less fibroblast proliferation and lesser granulating tissue.
Based upon all the findings it was concluded that the Prolene-Vicryl composite mesh is safer and more effective in terms of post-operative complications and outcomes.

6 mice in this group were treated with SN at 20 mg/kg intraperitoneally (i.p) and any effects on righting reflex recovery time were noted.
Sodium Thiosulphate (ST) alone (Group 27)
A group of 6 mice in group 27 were treated with ST at 600 mg/kg intraperitoneally (i.p) and any effects on righting reflex recovery time were noted.
Aqueous Garlic Extract (AGE) + Sodium Nitrite (SN) (Group 28)
The mice in group 28 were treated with AGE + SN at 750 mg/kg and 20 mg/kg intraperitoneally (i.p) respectively and righting reflex recovery time was noted.
Aqueous Garlic Extract (AGE) + Sodium Thiosulphate (ST) (Group 29)
A group of 6 mice in this group were treated with AGE at 750 mg/kg and ST at 600 mg/kg intraperitoneally (i.p) and righting reflex recovery time was recorded.
Sodium Nitrite (SN) + Sodium Thiosulphate (ST) (Group 30)
A group of 6 mice in group 30 were treated with SN and ST at 20 mg/kg and 600 mg/kg intraperitoneally (i.p) respectively and righting reflex recovery time was recorded.
The efficacy of the antidote estimated was based upon the reduction in righting reflex recovery time.
The righting reflex recovery time that was close to 1 hour was determined against KCN regimen. AGE was tested as potential antidote against sub-lethal KCN toxicity at dose regimens 250, 500 and 750 mg/kg intraperitoneally as well as orally at dose regimens 250, 500 and 750 mg/kg 5 minutes before and 5 minutes after KCN administration. SN and ST were tested at 20, and 600 mg/kg respectively as antidotes against sub-lethal KCN toxicity, 5 minutes before and 5 minutes after KCN administration. These were also tested in comparison and a dose with minimum recovery time was noted. A comparison was made between the efficacy of AGE and SN or ST or SN + ST as potential antidote against sub-lethal KCN toxicity. After 48 hours 3 mice from each group was sacrificed for postmortem examination.
For this purpose the righting reflex recovery time and survival data was collected for each mouse challenged with KCN. A group of 3 mice was tested with each increasing dose of KCN to create dose response curves for both righting reflex recovery times and percent survival. Increasing doses of KCN increased the recovery time of the righting reflex. The dose 5.5 mg/kg of KCN showed the righting reflex recocery time mean 64.66 ± .333 min and was selected for trials.
AGE (750 mg/kg) showed the most significant results as compared to ST and SN alone as well as in combination. Second most effective drug was ST as it showed better results than SN. Treatment results were more pronounced in 5 min pre-KCN groups as compared to 5 min post-KCN groups.
From this study it was concluded that the aqueous AGE is an effective antidote against sub-lethal KCN toxicity as the recovery times indicated that its effects are more pronounced than SN and ST, secondly, as it is easily available and very much cheaper in Pakistan and due to easy unavailability of SN and ST, it is effective antidote that could be used in the field against sub-lethal KCN toxicity with comparatively better results both orally and intraperitoneally.

Publisher: 2013Dissertation note: Medetomidine HCl (alpha-2 adrenergic agonist) is a highly potent sedative and analgesic drug being used extensively in veterinary practice. It produces reliable degree of sedation, muscle relaxation and analgesia in different animal species.
Hypothesis:
On the basis of existing knowledge about medetomidine HCl it is hypothesized that medetomidine anesthesia alone as well as in combination with other anesthetics can overcome the prevailing hazards of different anesthetics.
Goals:
The goals of study were to investigate clinical suitability of "Medetomidine HCl" an alpha-2 adrenoceptor agonist drug alone and in combination with other drugs in different animals. A detailed clinico-biochemical study was carried out to explore the various aspects of this novel sedative and analgesic drug in different animal species. Analgesia was evaluated by checking presence and absence of various clinical reflexes and by performing certain surgical procedures under experimental conditions. Different experiments were designed in different animals to investigate the sedative and analgesic properties of medetomidine HCl. In dogs a clinico biochemical study was designed to see effect of this drug on clinical and hematological parameters at different doses alone and in combination with gas anesthesia. In equines the combination of this drug with other routinely used sedative and analgesic drugs was evaluated. In another study in bovine calves the epidural effect of this magic drug was evaluated. In cats this drug was evaluated in combination with Ketamine during major surgical intervention.
Methodology:
The parameters used to evaluate analgesia revealed that Medetomidine has greater potential to lessen the pain during minor and major surgical interventions in different animals. However, its epidural use also produced good analgesia of perineal region and at higher doses used epidurally its results can be compared with lignocain which is an ideal local anesthetic agent. Medetomidine produces general sedative effects after absorption from epidural space into general circulation. It was proved that in equines the drug can be used in combination Propofol, Ketamine and chloral hydrate for ideal sedative and analgesic effects and it compensated the side effects offered by these drugs when used alone. In addition it has an edge over other sedative drugs on account of its undetrimental effect on various physiological parameters of the animals. Detailed Clinical and hematologic studies have proved that Medetomidine "a novel sedative and analgesic" is the drug of choice for restraining, examination, minor and major surgical manipulations in equine, bovine, feline and canine species and it produces minimum untoward effects.
This study will definitely open the new horizons to choose good anesthetic agents alone or in the form of cocktail to minimize the hazards of conventional drugs to save the economics of country. Medetomidine was used in four different animal species (equine, bovine, canine and feline). In canine the drug proved to be an effective sedative and analgesic drug aone and in combination with volatile anesthetic giving anesthetic sparing effects and exerted minimum effects on clinical and hematological parameters. In felines medetomidine effectively replaced an older and commonly used drug xylazine for combination anesthesia for surgical interventions. In bovine the drug was used as epidural anesthetic and proved to give ideal local effects. In equine medetomidine HCl was used effectively in combination with other anesthetics and enhanced sedation, analgesia, induction, recumbancy and recovery paramerts. A prolonged and stable recumbancy period enables the surgeons to carry out major surgical interventions smoothly and without hazards. In past many drugs have been trailed in veterinary practice as sedative, analgesic and anesthetics like clonidine, xylazine and atipamazole but medetomidine HCl has replaced these drugs in terms of safety, efficacy and effectiveness.
In review of results of present studies it is recommended that medetomidine HCl can be used effectively for anesthesia in animals. In present study medetomidine HCl was trailed as anesthetic drug in different animals in variable experimental conditions and has proved to be an ideal sedative and analgesic. It can be used to handle different surgical conditions like suturing, removal of a tumour and cyst, to drain abcess, eye enucleation, roaring operation, cropping, tail docking, tenectomies, neurectomies, tracheostomy, dehorning and correction of prolapse. The drug can also be implied effectively alone or as preanesthetic in different major surgical interventions like evisceration, enterotomies, intestinal anastomosis, castration, penile amputation, spleenectomy ovariohysterectomy and cessarian section. In different experimental trails medetomidine HCl has shown its anesthetic efficacy alone and in combination with other drugs. It variably minimises the side effects and risk and dose rate of other anesthetic drugs used in combination. In addition the combination of medetomidine HCl prolonged the duration of surgical anesthesia and provided ideal analgesic effect. Anticipated difficulties were time frame for the conduct of trials and financial constraints faced which may have hampered clarification of some findings owing to the low number of animals in different groups this difficulty may be faced by future researchers especially in third world countries. Further studies and research could include effects of alpha-2 drugs for treating colic in equines and the evaluation of this drug in orthopedic surgery. And for Future research can be planned on muscle metabolic changes during and after anaesthesia in horses. With these techniques valuable information may be gained that would otherwise be overlooked. The present investigation was mainly undertaken to study the anesthetic role of medetomidine HCl in different animal species in order to deepen the understanding of physiologic and biochemical parameters during and after anaesthesia must be fully clearified. At the end there were some unanswered questions which can be effectively addressed if other aspects of this drug are studied. Some other aspects of medetomidine anesthesia need to be explored further in the future studies.

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.

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).

Publisher: 2014Dissertation note: Dogs are amicably kept as a pet all over the world. Diversity in cultural trends in Pakistan is
paving way towards increasing awareness of the society with regards to a promising humananimal
bond. Hence, the tendency of people in metropolitan cities, such as Lahore, in keeping
dogs and cats as pets, has increased dramatically over the years. Not only do people keep pets,
rather also seek expert professional care in treatment of their animals. Liver is a major organ of
body located in the cranial abdomen below diaphragm. It produces major plasma proteins,
clotting factors and metabolizes carbohydrates, proteins and lipid molecules. Besides, it also
detoxifies many toxic metabolites into soluble and extractable products. It also acts as storage for
iron, glycogen and some other compounds. It also plays role in eliminating and excretion of
worn-out blood cells in the form of bile. Due to its major functions it is much prone to damage
and its mutual sickness is reported (Adam, 2003). Hemostatic anomalies in liver diseases are
mostly found in dogs and increased prothrombin time (PT) and activated partial thromboplastin
time (APTT). In hepatic disease 93% dogs had one of the abnormal results of PT and APTT
(Badylak et al. 1983).
Conditions as well as low or incomplete blood supply or shock damage, blockage of bile,
long-lasting liver sickness, portovascular variances, toxin produce inside the bacteria wall, and
resistant dysfunction altogether add toward hepatic defenselessness to infectivity also change the
role of the reticuloendothelial structure (Center et al.2006). In the United Kingdom (UK),
chronic hepatitis (CH) twelve percent was found during postmortem of the dog (Watson et al.
2010). Acute hepatitis (AH) and CH can cause toward lethal liver dysfunction that can lead to
inadequate otherwise weakened liver restoration. Restoration take place through double

resources, specifically reproduction of developed hepatocytes and in the case of held back
hepatocytic replication, by production of the native stem cell precursor cell population in liver
diseases (Roskams et al. 2004; Santoni-Rugiu et al. 2005; Katoonizadeh et al. 2006). Liver play
major role in the majority of metabolism, so liver infections can affect the purpose of further
tissues. Most common effect stands going on the brain and excretory system (Wettstein et al.
2003; Hilgard and Gerken, 2004). Hyperfibrinolysis can be seen in cases of later hepatic liver
infection and cirrhosis because of reduced thrombin-activatable fibrinolysis inhibitor (TAFI)
(Van Thiel et al. 2001; Colucci et al. 2003).
The major reasons of sickness and death in dogs are cirrhosis and long-lasting liver
problem (Klein et al. 2010). The liver size is measured by a simple method through the
ultrasonography. The measurements were taken in both planes transverse and longitudinal
scanned. There was good relation in both measurements. Through this study it was concluded
that liver size has no relationship in breed or size of the dog. This study also showed that liver
size easily measure through ultrasonography (Barr, 2008). Infectious canine hepatitis (ICH) is a
universal viral disease caused by canine adenovirus-1 (CAd V-1) (Decaro et al. 2007). Young
dogs under the age of 2 years have more mortality rate (Akerstedt et al., 2010; Thompson et al.
2010). ICH has three clinical forms that are Mild, acute and per acute (Stalker and Hayes, 2007).
Canine adenovirus-1 has resemblance for vascular endothelium, mesothelium and hepatic
parenchyma and the main pathological characters of ICH are edema, hemorrhages and focal
necrosis (Chouinard et al. 1998). There is variation in the incubation period of hepatitis. The
incubation period of infectious canine hepatitis is 4-7 days. Infectious canine hepatitis can
increase temperature, despair, loss of starvation, sneezing, edema, excretory problem. But in
severe cases animal has pale mucous membrane increase liver size and vomiting. Severe cases

will develop bleeding disorders, which can cause hematomas to form in the mouth (Sanchez-
Cordon et al., 2002; Greene, 2006). Clinical diagnosis may be based on the clinical and
pathological findings, which may include moderate to severe leukopenia, neutropenia,
lymphopenia and thrombocytopenia. Serum alanine aminotransferase and alkaline phosphatase
activities may be increased. Coagulation parameters, PT and PTT are variably affected.
Proteinuria (albuminuria) as a reflection of the renal damage caused by the virus can usually be
detected (Sellon, 2005; Greene, 2006).
Clinical signs in pets vary from ill to asymptomatic. These may include anorexia,
vomiting, weakness, depression and poor hair coat. Production of albumin in the body takes
place only in liver, so liver problems cause low albumin production in body. It leads to
hypoalbuminemia (Bunch, 2003). During chronic liver disease liver enzymes value may be
normal or decrease. For example in cirrhosis the hepatocytes start to die and cannot make liver
enzyme. The liver has capacity up to 30 times the usual level for the processing of bilirubin. At

serum and bilirubinuria can be identified (Richter, 2004). In chronic hepatitis the liver enzymes
ALT/AST with change ALP/GGT rises. With progressing disease bilirubin rises and albumin
levels will drop. Chronic hepatitis causes the serum bile acids abnormal level. In this study dogs
with chronic hepatitis all cases assessed had atypical bile acid concentrations. Acquired shunting
or advanced liver insufficiency leads to increased blood ammonia concentrations (Strombeck,
1988). In study it was confirmed that coagulation anomalies are more common in dogs in case of
chronic hepatitis and cirrhosis that indicated significantly lesser platelet counts (Prins et al.2010).

Publisher: 2015Dissertation note: According to the economic survey of Pakistan 2013-14, livestock sector contributed about 55.9 and 11.8% to the agriculture and national GDP, respectively.Total cattle population in the year 2013-14 is 39.7 million. Total milk and meat production contributed by cattle is 18,027000 tons and 18,87000 tons respectively (Anonymous 2013-14) . In Pakistan, the chiefhindrance in performance and health of animals are parasitic diseases including tick born. Ticks have been easily grown and reproduce in the optimal climate of tropical weather in Pakistan. In Pakistan, there are huge number of species and genera of tick fauna (Durrani and Shakoori, 2009).
Tick-borne diseases include babesiosis, theileriosis, anaplasmosis, lymedisease . Among these tick-borne diseases anaplasmosis is one of the vital diseases which is responsible for the substantial economic losses in term of high morbidity, mortality and production losses that are decreased in milk, meat and other important livestock productions. Throughout the world, the “tick-borne diseases” are extensivelyspread in sub-tropic and tropicareasand Pakistan also includes in these areas(Khan et al. 2004). Moreover, anaplsamosis is non-contagious disease but also known to be infectious, transmission of which occur through mechanical means that includes the flies or tick bites. As well as different equipment that are using during tattooing or castration, in dehorning and needles also causes transmission (Aubry & Geale. 2011).
Anaplasma marginale (A. marginale) is the major cause of Bovine anaplasmosis and this speciesbelongs to the genus Anaplasma (“Rickettsiales, Anaplasmataceae”). The most important 20 ticks species which cause transmission are Argaspersicus, Boophiludecoloratus, B. microplus, B. annulatus, Dermacentoroccidentalis, D. andersoni, D. variabilis, D.albipictus, Hyalommaexcavatum, Ixodesricinus, Ornithodoroslahorensis, Rhipicephalussimus, R. saniguineus, and R. bursa(Marchette & Stiller. 1982), on the other hand, Boophilusmicroplus found as a major contributor in cause of anaplasmosis (Tick Fever Research Centre, 1996).
The family anaplasmatacease was classified in 1957 of the order Rickettsiale. In the genera Anaplasma, Aegyptianella, Haemobartonella and Eperythrozoon, this family was rationalized (Ristic&Kreier. 1984), and projected a combination based on analysis of genes sequences for protein on surface and ribosomal RNA (16S)(Dumler et al. 2001; Walker & Dumler. 1996). Anaplasma is a rickettsial, obligate intracellular bacteria found in red blood cells. Disease is characterized by fever, anemia and jaundice. Infection is transmitted by ticks or mechanically by biting insects or contaminated hypodermic needles or surgical instruments (Tylor et al. 2007).The most significant parasite is Anaplasma speciesthat is transmitted by at least twenty different species of ticks. But among those all mostly Bmicroplus causes Anaplasmosis (Rajput et al.2005).
A. marginale is etiological agent of bovine anaplasmosis (Bram, 1957; Dumler et al., 2001; Kocan et al., 2000). A. marginale persistently infect both cattle and ticks and help as infection reservoirs(Kocan et al. 2003). Bovine erythrocyte membrane bound parasitophorous vacuoles is the site for replication of this obligate intracellular organisms. Dogs, humans, wild and domesticated ruminants are the species effected by A. marginale. This anaplasma genus is an obligate intracellular parasite of vertebrate hosts. In cattle, theA. marginal, A. phagocytophilum, A. central, and A. bovisare major pathogenic species producing diseases (Inokuma et al. 2007). Researchers suggestedthat in cattle, some unidentified Ehrlichia or Anaplasma species are present (Awadia et al. 2006). For this pathogen, which cause the persistent infection, the reservoirs are generally present in different host like tick or mammalian (Kocan et al. 2004). The wide range of different ruminant can be affected by Anaplasmabecause the species of anaplasma are not considered as strictly specific for any particular host specific(Kuttler. 1984).
The A. marginalecan only be developed inside the RBCs of bovine (Richey et al. 1981). After invading the erythrocyte the tick multiplies and form almost eight initial bodies, they then get enlarge in the outer membrane and give it an appearance of a large dot. The organism gets mature in the outer membrane of RBC and force the infected RBC to get rupture due to infection. By rupturing the outer membrane where it previously multiplied come into the blood stream to infect the other RBCs. On the progression of progresses, more number of erythrocytes is infected by this organism and afterward destruction of erythrocytes occur (Stewart et al. 1981). Upon the clinical signs and symptoms are appear when the 15 percent of the RBCsare affected by the parasite(Radostits et al. 2006). The symptoms of the disease are pyrexia, anemia, icterus, hematuria, anorexia, muscular tremors, dyspnea, depression, lethargy, constipation and yellow colour of mucous membrane (Bram et al. 1983), low milk production, miscarriage and sometime mortality (Alderink and Dietrich. 1981).
The mature RBCs are the site for multiplication after the invading by A.marginale. In the acute case of Anaplasmosis the higher number of RBCs are affected by the parasite for example more the 109 red blood cells per ml and after that the disease is categorized by death, abortion, loss of weight and anemia, and the survival cattle that are infected act as reservoirs for transmission of the disease in the herd level(De Echaide et al. 1998).The haematological profile can be used as useful diagnostic tool in anaplasma infection(Van Wyk et al. 2013).There is significant decrease in packed cell volume (PCV), Hemoglobin (Hb) and erythrocytes count.Serum biochemical analysis showed increased total protein,bilirubin and alanine aminotransferase enzyme (Sharma et al. 2013). A diagnosis ofcattle anaplasmosis may be made tentatively based on geographical location, seasonal variation and presenting clinical signs or necropsy finding in infected animals (Kocan et al. 2010).
A.marginale,can affect throughout the life of cattle but disease severity is dependent on the age of the cattle. The clinical disease is less occurs in the calves and disease is very rare under the age of 6 month. The mild type of the disease can occur in the animal, which are between the ages of six month to one year. The acute type of the disease occurs in the animals between the ages ofone to twoyears but this disease is never fatal for the animal between these age groups.Whereas if the acute type of the disease occur in the adult animal that are more than two year aged can face the serious consequences and this disease can cause the death of the cattle with higher percentage (29 to 49%) of mortality (Kocan et al. 2003; Richey. 1991). Beside the animal age at the infection time, onceA. marginale infect animals, the animals become carrier for the infection throughout of animal life, with or without the clinical signs of the infection (Richey et al. 1991). The animal with the strong immune system are recovered from the acute type of anaplasmosis (Palmer et al. 1989). The regular cycle of ten to fourteen days are present in the carrier animals and in this cycle there are more or less number of RBCs are infected with the pathogen(Kocan et al. 2003;Kieser et al. 1990; Viseshakul et al. 2000).
For the proper diagnosis of the disease and quality control in livestock, the most important aspect is the preciseor correct detection of pathogen that is spread by the tick.In 1990, with the beginning of the diagnosis with the techniques on the molecular bases the researcher produced more accurate and sensitive techniquesfor pathogenic species determination and these techniques are still used till to date (Ahantarig et al. 2008). The Giemsa staining method is used for the diagnosis of anaplasmosis in bovinesthat can be achievedby finding ofA.marginalein smear of blood from animals that are affected clinically. For the carrier animals or pre symptomatic animals thistechnique is not reliable. In these types of conditions, the serological tests are used for general diagnosis of infection by detection of antibodies. This is confirmed by molecular detection methods. A.marginaleappears as “dark staining blue purple bodies” measuring about 0.3 to 1 µm in length. A. centrale inclusion bodies are well differentiated by their location. Serological diagnosis can be done for the identification of infected cattle, DNA based test can be used for the molecular diagnosis(Stuen et al. 2011).
The conventional parasitological technique like Giemsa staining always remained gold standard for diagnosis of Bovine anaplasmosis. Light microscopy of thin blood smears stained with giemsa stain may facilitate demonstration of A. marginale organisms in the erythrocytes (Kocan et al. 2004) .As giemsa staining method is not applicable for the detection of subclinical infection. Therefore PCR can also be used as a diagnostic tool for the detection of A.marginale in this technique primer pairs are used which resulted in the amplification of only their target DNA i.e. A.marginale(Munderloh et al. 2004).
In the United states, for the treatment of anaplasmosis, the specific approved compound is the tetracyclines that include chlortetracycline or oxytetracycline(Kuttler. 1980). Oxytetracycline, Chlortetracycline and Tetracycline can be used to treat anaplasma infection in cattle .Among these Oxytetracycline is the most used drug at the dose rate of 10mg/kg body weight. While single dose of imidocarb dipropionte can be used at the dose rate 3mg/kg body weight (De Waal 2000).Imidocarb dipropionate with the dose of 3 milligram/kilogram body weight repidly treat A. marginale(anaplsmosis), on the other hand, same drug with double dose (6 milligram/kilogram body weight) and each dose has gape of two weeks,fail to cure A. marginalecarrier heifers(McHardy & Simpson. 1974). The animals recovered completely with imidocarb dipropionate (Akhter et al. 2010).The E elephantina and Aloemarlothiileaf extracts demonstrated good activity against rickettsia. These 2 plants along with Usanguineaand Rtridentata in certain concoctions are believed to be effective against anaplasmosis (Naidoo 2004).

Publisher: 2015Dissertation note: Poultry industry is the most effective and economical source of animal protein. Because of increasing future demands, poultry industry is unable to narrow down the animal protein supply and demand gap. Poultry producers are looking forward for using the alternate source of chicken meat, which in the future will come from pigeon and quail meat. It will be very help full for increasing gross domestic production (GDP) through livestock sector (Basit et al. 2006).
Pigeons have been domesticated to live close with human beings. Pigeons originate from the rock dove in Europe, have been partially domesticated and carried to all parts of the world. Pigeons have been divided into three groups.
1) Poultry pigeons
2) Carrier and racing pigeons
3) Fancy and feral pigeon
Pigeons are easily bred to produce a variety of plumage or to provide squabs for the table (Basit et al. 2006).
It is very well known that internal parasites cause great loss to the host, by different ways. These parasites live at the expense of host depriving them from the nutrients essential for their growth. Moreover they cause mechanical harm by producing inflammation and tissue damaged. Protozoa inhabiting the digestive tract of birds are responsible for considerable economic losses. Heavy infestation of the parasites affect the health of birds with loss in the body weight, retarded growth, unthriftiness, damage to the gut epithelium, fertility disturbances, emaciation and death especially in young birds (Urquhart, 1996).

Common name of Trichomonas gallinae is canker, frounce and roup. Predilection site of this parasite is esophagus, crop and proventiculus. It belongs to the family Trichomondidae and class Zoomastigophorasida (Taylor et al. 2007).
Body of T. gallinae is elongated, ellipsoidal os pyriform. Its size is 5-19 × 2-9 μm. It has four anterior flagella that arise from blephroplast, having undulating membrane that does not reach the posterior end of body and free posterior flagellum is absent. Its axostyle is narrow and protrudes 2-8 μm from the body and its anterior portion is flattened into a spatulate captulum. Its parabasal body is hook shaped and parabasal filament is present (Taylor et al. 2007).
The host of T. gallinae is pigeon, turkey, chicken and raptors (hawks, falcons and eagle). As the method of reproduction is concerned it reproduced by longitudinal binary fission. There is no sexual stages and cyst are present in its life cycle. Lesion present in the turkey and chicken are most commonly in the area of crop, oesophagus, pharynx and no lesion are found in mouth (Taylor et al. 2007).
Size of trophozoites of T. gallinae is about 7-11 μm. Its shape is varied from oval to pyriform. It has four flagella and a fifth recurrent one, which did not become free at the posterior pole. Size of nucleus is about 2.5–3 μm, oval in shape and situated closely below the basal bodies of the flagella. Its axostyle consisted of a row of microtubules that is running from the region of the apical basal bodies to the posterior end of the cell (Mehlhorn et al. 2009).
Infected pigeons show wild signs of depression, lose weight, stand huddled with ruffled feathers and may fall over when forced to move. There is an accumulation of greenish fluid present in the mouth and crop containing large number of trichomonads in it. Yellow, necrotic lesions are present in the esophagus and crop (Taylor et al. 2007).

Trichomonas gallinae is a causative agent of trichomoniais in birds. It affects mostly to the young birds and causes death in them, especially in pigeons within 10 days. This Protozoa is present in the gastrointestinal tract of birds and causes greater financial losses. Clinical sign of diseased birds are dull, depress and having yellow color diarrhea. Morbidity rate of this disease is high in birds. If infected birds are not treated, it causes high mortality in diseased birds, due to this reason this problem become very important. Trichomonas gallinae presents in upper digestive system and respiratory system. So it affects both digestive system and respiratory system. It is mainly found in pigeons, but turkey, chicken, hawks, mourning doves, golden eagles, falcons and bustards may also be infested with this protozoa (Saleem et al. 2008).
Small, whitish to yellowish caseous nodules are found in the esophagus, pharynx and crop. Their size increased and may remain circumscribed and separate, or may become thick, caseous, necrotic mass present in lumen. The circumscribed disk shape lesion are known as yellow buttons. Size of nodule is 1 cm or more and found in liver, lungs and other organs (Taylor et al. 2007).
Infection spread to turkey and chicken by drinking contaminated water. The pigeon and other wild birds are also source of infection, which also use the water source. T. gallinae enters in the water through mouth and not from feces of the wild birds. Source of infection is direct contamination because this organism is very sensitive to drying and no cyst are found (Taylor et al. 2007).
There are more chances of trichomoniasis in young one than in adult pigeons. During feeding carrier pigeons transmit this disease to their young ones. The pathological lesions associated with trichomoniasis is inflammation, ulceration, and necrosis in nature. These lesion are more predominant in the oral cavity, esophagus, crop and proventiculus (Kennedy et al. 2001).

This disease is present worldwide. A clonal strain of previously described organism has been recently developed as the cause of widespread disease of birds in Europe and causes a grate economic losses (Ganas et al. 2014). In Britain, this infectious disease was first described in 2005. This disease causes significant mortality in birds which results in decreased population of green finches and passenines (Robinson et al. 2010).
T. gallinae affects upper digestive system of birds and results in pathological changes in structure of different parts of digestive system. It causes slight inflammation of mucosa to large caseous lesions of esophages. These lesion sometime block the lumen of esophagus. Due to this secondary infection of parasites, bacteria and virus takes place in diseased birds. Different strains of parasites move toward other organs such as liver, air sacs, lung, and brain. They causes necrosis of these organ, which leads to the death of birds (De Carli et al. 2002).
Prevalence of T. gallinae infection is different in different age of birds. Prevalence increased with the age of nestling (Krone et al. 2005). A higher prevalence of Trichomoniasis has been recorded in pigeons in Pakistan season wise prevalence has been recorded to be 43%, being non significantly higher in April (56%) than in March (30%). Trichomoniasis positive cases show a significant decrease in hemoglobin concentration, number of monocyte, packed cell volume, body weight than healthy birds (Saleem et al. 2008).
T.gallinae is a parasite of different species of birds ranging columbiformes, diurnal raptors and captive gallinaceous birds. It causes stomatitis, esophagitis and ingluvitis (Bunbury et al. 2007).
This disease is recently emerged in British passerines. This parasite has caused high mortality in finch and their population is decreased and this disease is also spread to continental Europe (Chi JF 2013).

The sequence of T.gallinarum is different from Tetratrichomonas gallinarum that is another trichomonad of birds, but it is genetically similar to Trichomonas Caninistomae that affect dog and cat and causes oral infection. Pigeons are prey of dog, so there is possibility that T. gallinae may have infected (carnivorous) mammals in the past (Gasper et al. 2007).
This disease causes large economic loss of avain livestock and also cause problems for wild species of birds. In UK T. gallinae has caused the death of greenfinches (Lawson et al.2006). Trichomoniasis was first reported in 2005 in Britain. It was discovered in finches. It caused large scale mortality in finches with population decline (Robinson et al. 2010; Lawson et al. 2011). In 2007 this disease is reported in finches in the Canadian Maritime provinces, southern Fennoscandia and northern Germany (Lawson et al. 2011). This disease caused high morbidity and mortality in finch population in Britian. It is estimated that about 1.5 million greenfinches which represent the 35% of national population have been died with this disease (Lawson et al. 2011).
In this disease multiple foci of caseous necrosis is seen in oral, esophagus and crop mucosae. There is heavy infiltration of inflammatory cells especially heterophill in these areas. There is multiple foci of necrotic inflammation is seen on liver. Due to excessive infiltration of heterophils in there is thickening of mucosa of easophagus. Necrotic material is also seen in mucosa and submucosa of easophagus. There is necrosis on the tip of villi of intestine and necrotic materials is seen in the mucosa of intestine (Al Sadi et al. 2011).
Trichomoniasis occurred more frequently in young than adult pigeons. High prevelance of trichomoniasis have seen in male than female pigeons (Al Sadi et al. 2011). Nestling birds are more susceptible to this disease than other birds. In Tucson, Arizon study was conduct and this study show that T. gallinae was present in oral cavity of 85% nestling coopers hawks compared to
Introduction

only 1% of breeding age hawks. This disease is more prevalent in young pigeons. T. gallinae is sensitive to environmental pH. Trichomonas gallinae develop well when pH is between 6.5 and 7.5 (optimum 7.2), but cannot survive in more acidic pH. In fledgling and breeding Coopers Hawks pH of their oral cavity is acidic, so they are less susceptible to trichomoniasis and this is very important in differential prevelance among age group of birds (Urban et al. 2014).
Trichomonas gallinae changes the blood picture of infected birds. It causes decreased values of Hb, PCV and monocytes in infected pigeons than the healthy pigeons, while TLC, heterophils, lymphocytes and eosinophils are increased in disease pigeons than the healthy pigeons (Seddiek et al. 2014).
