Publisher: 2001Dissertation note: Sixteen Nih Ravi buffaloes having postpartum period of 197±27.48 (Mean ±SE) days were randomly divided into 2 equal groups viz A and B (n=8). Estrus was induced and synchronized in buffaloes of group A by administering 75 mcg GnRH analogue (25 mcg/ml) intramuscularly on day 0 (first day of experiment). The buffaloes, showing estrus during day 0 to 7 were inseminated and were not given PGF2 alpha injection. The animals those did not exhibit signs of estrus till day 7, were injected with 0.150 mg Cloprostenol (0.075 mg/mi) intramuscularly. Buffaloes of group B served as control group and were not given any hormonal treatment. Animals in group A were observed for estrus from day 0 to 16 of the experiment, whereas the buffaloes of group B were bserved for natural estrus from day 0 to 26. Estrus was detected with the help of teaser bull. Artificial insemination was carried out mainly on the basis of standing heat. In group A, 4 buffaloes responded to the treatment and exhibited the estrus. One buffalo exhibited the estrus on day 5 following the injection of GnRH whereas three buffaloes exhibited the estrus on day 2, 4 and day 5 following the injection of PGF2 alpha. In group B, 2 buffaloes exhibited natural estrus, one on day 3 and the second on day 11 of the experiment.
Variation in the interval to estrus may be because of huge difference in the postpartum days of animals. The duration of estrus in group A (24.62±O.96h) was significantly different (P>O.05) as compared to group B (20.25±O.33h). No difference was observed between group A and B towards the expression of estrus symptoms. Two animals from group A, conceived at induced and synchronized estrus at first service, whereas one animal conceived from group B.
It is concluded that the select synch protocol is useful for synchronization of estrus in buffaloes with promising conception results. It is indicated that select synch protocol is also applicable for induction of estrus in buffaloes of variable postpartum intervals, it seems that select synch protocol will be an effective tool if used in cycling buffaloes during early postpartum days.

Publisher: 2010Dissertation note: The study was conducted to evaluate the effect of mannan-oligosaccharide in small bowel resection. Intestinal resection is conducted in various pathological conditions, which is necessary in alleviation of the anomaly but produces ill effects related to the physiological functioning of the resected part. Various post-operative treatments have been suggested in this regard. Prebiotics can serve as an important dietary and clinical nutritive substance with potential to stabilize aftermath. Dogs with jejunal resection were used as an experimental animal and were divided into three groups in this study. Groups were Control (con), MOS-lower dose (MOS-LD) fed 2g MOS and MOS-higher dose (MOS-HD) fed 4g MOS in addition to 400g standard diet daily. Dogs were assessed for glucose, cholesterol, white blood cell counts on day 0, 1 5, 30, 45 of MOS supplementation. Ammonia, microbiological analysis for E.coli, total aerobes and ('lostridium per/ringens were done on fecal samples collected between day 24 and 28 of MOS supplementation. Fecal scoring system was used to study alleviation of diarrhea in two periods with each of 5 days. Period 1 was from day 18 to day 22 and period 2 was from day 41 to day 45 of MOS supplementation. Repeated measures and one way ANOVA was used for analysis of data. Positive effects of MOS were evident on relieving diarrhea and increasing blood lymphocytes. Total aerobes and clostridium count decreased significantly. This study paved way for further studies in the assessment of potency of MOS and other Prebiotics in gastrointestinal surgeries and their inclusion in management of short bowel and the therapeutic arsenal.

Publisher: 2012Dissertation note: Hepatitis C is an infectious disease affecting primarily the liver, caused by the hepatitis C virus (HCV). The infection is often asymptomatic, but chronic infection can lead to scarring of the liver and ultimately to cirrhosis, which is generally apparent after many years. In some cases, those with cirrhosis will go on to develop liver failure, liver cancer or life-threatening esophageal and gastric varices.
The present project was carried out to study the prevalence of laboratory based confirmed patients of Hepatitis-C in various public, private hospitals and in high risk groups among the population of Lahore metropolitan and its distribution and pattern with respect to person, time and place. Second part of the project was designed to study the risk factors of Hepatitis-C patients from out patient departments of various public and private hospitals of Lahore. Individuals at high risk from different organizations and occupations across the city population of Lahore metropolitan were also included in the study. The third part of the project was designed to investigate the distribution of genotypes of Hepatitis-C virus among patients through RT-PCR and theireffect on viral load, various haematological and biochemical parameters.
Project-I
Study-1: To estimate the prevalence of hepatitis C in various public and private hospitals of Lahore Metropolitan among different groups a total of 1399 individuals were tested to estimate the hospital based prevalence of HCV. Out of these 233 individuals produced positive result for Hepatitis-C virus infection. The overall hospital based prevalence was estimated to be 16.66% during the year 2009. The current study revealed that the highest prevalence was estimated in Dialysis patients and Organ recipients (41.17%) followed by General Patients of age > 12 years (14.60%) and pregnant women (10.84%). It was further observed that the least affected group was the Children of age ? 12 years (3.85%).
Study-2: The results of estimated prevalence of Hepatitis C virus infection in high risk groups from the population in and around Lahore revealed that the highest prevalence was estimated in patients with HIV/AIDS (36.36%) followed by injecting drug users (36.09%), blood donors (17.78%), long rout truck drivers (14.70%), house hold and direct contact personal (14.6%) and prisoners (14.28%). It was also find out that the less affected groups were police department (10.66%), staff nurses and other health care workers (9.87%) and barbers and beauticians (6.97%) while doctors and dental surgeons were least affected (1.32%) among the high risk groups.
Study-3: To find out the pattern and distribution of HCV patients with respect to person place and time a total of 924 patients were selected from the registry of Provincial Hepatitis Control Cell Lahore through systematic random sampling. Out of these, 154 fulfilled the inclusion criteria. Among these, 90 were male and 64 were females. Average age of male and female patients was 35.88±10.49 and 37.78±9.12 years, respectively. The age difference between male and female patients was statistically non-significant (P-value>0.05). It was further observed that 147 patients were Punjabi and 7 were from other provinces. Moreover, It was found that the highest number of patients was observed during the month of December (n=18) followed by November, 2008 (n=15), March (n=15) and July, 2009 (n=14) while the least number of patients were observed during the months of September, 2008 and May, 2009 (n=10).
Project-II
To study the risk factors associated with HCV infection an analytical cross sectional study was conducted.
Study-1: Lower socio economic class, place of birth (hospital), delivery assisted by whom and breast feeding were significantly associated with HCV infection in children of age ? 12 years. The mean age of reactive and non-reactive general patients was significantly associated (P=0.012) with anti-HCV status. Marital status (OR=2.042), socioeconomic status, blood donation (OR=2.15), prescription by doctor or non-doctor (OR=2.664), route of drug administration, relative having hepatitis and towel sharing (OR=1.987) were also significantly associated (P<0.05) risk factors for HCV infection. The mean age of reactive and non-reactive pregnant women was 27.55±3.43 and 25.37±4.24 years, respectively. Educational level (OR=3.093) and occupational status (OR=2.228) were the important risk factors associated with HCV infection. Tattoo on the body (OR=11.833), comb sharing (OR=20.86) and razor sharing (OR=4.786) were significantly associated (P<0.05) with HCV infection. Pregnant women who gave the history of dental procedures and tooth brush sharing were 3.15 and 4.12 times more prone to get HCV infection, respectively. In 205 patients having dialysis and organ recipients 41.17% patients were reactive for Anti-HCV. Blood transfusion, glass sharing and qualification of the patients were significant factors in this group.
Study-2: In case of doctors/dental surgeons a significant association was observed with history of blood transfusion and duties in medical and surgical wards. The nurses who worked in surgical wards, visited beauty salons were significantly associated (P<0.05) with HCV infection. Among health care workers age, gender and other factors did not have any significant influence on the reaction of HCV. Among blood donors female to male ratio was 1:16.5. It was found that the occupational status (p=0.002), place of surgical treatment (p=0.035), history of blood transfusion (p=0.000), ever pricked by sharps (p=0.045), habit of injecting drugs (p=0.04) and glass sharing (p=0.017) were significantly associated with occurrence of hepatitis C in blood donors. In long route truck drivers geographical status, surgical procedure, dental treatment and family history were significantly associated (P<0.05). Among the injecting drug users, demographic factors like marital (P=0.007) and educational status (P=0.000) were found to be significantly associated with HCV infection. Furthermore, the behavioral factors; use of injectable drugs with reused syringes (P=0.003), sharing of syringes in groups (P=0.004), place of shaving (P=0.000), use of disinfected ustra (razor) (P=0.003) and razor sharing (P=0.000) were significantly associated with anti-HCV status for IDUs. Among HIV/Aids patients a statistically significant (P<0.05) difference was present among the ages of reactive and non reactive patients. Comb sharing has also a positive effect of HCV but all other factors were not contributing in this group. In Police personals odds ratio for married persons was higher (9.57) but statistically insignificant. The mean age for reactive persons was 39.75±8.24 years. A non-sexual contact with HCV patient and spoon sharing were significantly associated. In prison inmates skin infection and sexual involvement were significantly associated (P<0.000) with HCV infection. In the group of 43 barbers/beauticians age, working shift, tattoo on body (OR=19.5), injecting drugs (OR=19.5) and pre-testing for HCV (OR=19.5) were significantly associated with HCV infection. In house hold and direct contact group previous history of accidents and family history of HCV (OR=18.36) were significantly associated with HCV infection.
Project-III
A molecular epidemiological study was conducted in which the HCV reactive patients as tested by ELISA test were subjected to viral load and genotyping through RT-PCR. The positive cases of Project-I were included in this project. In the present study 558 patients were reactive for Anti-HCV. Out of these, 34 (6.09%) patients had Type-1 genotype, 67 (12%) patients were accounted for Type-2 and 410 (73.47%) patients were positive for Type-3. Multiple genotypes were seen in 19 (3.4%) patients, 9 (1.61%) patients had un-type able genotype whereas in 19 (3.4%) patients genotype could not be detected. According to the distribution of genotype-1, 1a was present in 30 (88.23%) while 1b was seen in 4 (11.76%) patients. In patients of Type-2 genotype, 2a and 2b were present in 54 (80.59%) and 13 (19.40%) patients, respectively. In patients having Type-3, 3a and 3b were identified in 353 (86.09%) and 57 (13.90%) patients, respectively. Furthermore, Bilirubin, ALT, AST, ALPT, viral load, Hb, TLC, DLC, Platelet and ESR were statistically same in all genotype.

Publisher: 2014Dissertation note: The snake venom has both neurotoxic and haemotoxic effects. The Pakistani spectacled black cobra venom is considered to be mainly neurotoxin and there is a need to evaluate its haemotoxic effects. This study aimed to determine the acute bio-physiological effects of LD50 dose of crude venom of cobraat different time intervals after I/M envenomation in mice.
The crude venom was obtained from the black cobra, Naja Naja karachensis found in the region of Mian Chanuu, Punjab and the venom was lyophilized. Twenty adult male mice, approximately 20g weight, were housed in cages for one week at the animal shed of University of Veterinary and Animal Sciences, Lahore. Blood was drawn by cardiac puncture after general anesthesia at time 0 from the five overnight-nonfed mice injected i/m with normal saline. Remaining mice (15 in number) were injected i/m with LD50 dose (1.2mg/kg) of cobra venom. Blood samples were collected from five animals at each time intervals of 1, 1.5 and 2 hours of envenomation. The hematological and biochemical parameters studied were complete blood count, estimation of plasma glucose, plasma total protein, plasma albumin, alanine aminotranferase and urea by commercially available enzymatic kits.
There was a significant increase in red blood cells count and its indices (haemoglobin, packed cell volume, mean corpuscular volume, mean corpuscular haemoglobin, mean corpuscular haemoglobin concentration) and platelets at 1, 1.5 and 2 hours after envenomation in albino mice compared to 0 hr.A significant decrease in the count of white blood cells was observedafter 1 hour of injection compared to 0 hr, however it was increased significantly after
2 hours of envenomation compared to 0 hour. The lymphocytes, monocytes and granulocytes percentageswere not changed after envenomation in mice.Plasma glucose showed a significant decrease at 1 hour of I/M injection compared to 0 hr that increased in subsequent time intervals compared to 0 hr in albino mice. The concentration of urea was significantly increased at 1, 1.5 and 2hours of envenomation in comparison with the concentration at 0 hour. The concentration of plasma total proteins showed a significant increase at 2hours of time interval as compared to 0, 1 and 1.5hours after envenomation in mice. The plasma albumin concentration at 1.5 and 2hours of time interval showed a significant increase as compared to that at 0 and 1 hour. The concentration of ALT also increased at any time interval.
Therefore it is concluded that the crude spectacled cobra venom is both neurotoxin and hemotoxic in nature.

Publisher: 2015Dissertation note: In the review by O’Reiley and his colleagues, Tuberculosis has been defined as a disease that affects the respiratory system foremost and its route of transmission from one animal species to another is by the airborne route along with consumption of un-pasteurized milk (O'Reilly, 1995) (De la Rua-Domenech, 2006) (Thoen et al. 2006). The review states that Mycobacteriumbovis causes tuberculosis in bovines as well as a number of wild animals such as goats, cats, dogs, pigs, buffalo, badgers, possums, deer, bison and non-human primates but most importantly it causes tuberculosis in humans. This makes the disease of significant public health importance due to its zoonotic nature.
The study was conducted in two of the largest dairy colonies in Lahore- Rakhchandra and Harbanspura dairy colony. 400 dairy animals (lactating) were selected from the target areas. 200 animals per field were chosen through convenience sampling. The research was divided into two parts. Phase 1 was concerned with screening of animals for bovine tuberculosis through performance of comparative intradermal tuberculin test (CIDTT) and followed by culturing of milk samples from animals that came positive. Phase 2 was concerned with testing of all human subjects who were in contact with the positively screened livestock. Since none of the human subjects showed any of the signs for tuberculosis, no testing of the humans could be performed.
The first step to animal testing was concerned with the screening of selected animals with comparative cervical intradermal tuberculin test (CIDTT). This involved the intradermal injection of bovine tuberculin purified protein derivative (PPD) and the subsequent detection of swelling (delayed hypersensitivity) at the site of injection 72 hours later (Anonyms, 2008a). The test was considered positive if the difference between the swellings on the two sites was more than 4mm and it was the mammalian site that showed more swelling. Once the results were read, the dairy farmers were asked a set of questions designed to identify risk-factors for zoonotic tuberculosis. The farmers responded to nearly all the questions that were posed to them.
Milk sample was collected from the animals that tested positive. 50 ml of milk was collected from the positive animals. Once collected, the milk bottles were quickly capped and labeled and put in the ice-box before being transported to Provincial Tuberculosis Reference Laboratory in Lahore. Staining followed by culturing of milk samples for the isolation of Mycobacterium bovis was then proceeded with. For the purpose of culturing two types of media were prepared before-hand-Lowenstein Jensen (LJ) media and LJ-pyruvate media. LJ medium allows the growth of Mycobacterium tuberculosis, whereas LJ with pyruvate medium allows the growth of Mycobacterium bovis.
Petroff’s method was employed for the processing of milk samples which originally is used for sputum processing (Anonyms, 2009). The process was altered to suit our requirements. Once processed 300ul of pipette tips were used to place 100ul of processed sample on pre-marked slides for ziehl-neelson staining and 120ul on pre-made media slants a total of 4 bottles, 2 each of LJ media and LJ pyruvate media for duplication of results and to act as control. The bottles were checked for growth every week on Monday till 8 weeks of time.
At Rakhchandra dairy colony the tuberculin test done on 200 animals revealed only three (3) positive animals. Thus the prevalence of TB in Rakhchandra came out to be 1.5%. Out of 200 animals in Harbanspura dairy colony, six (6) animals showed hypersensitivity reaction and were positive. Prevalence of TB in Harbanspura came out to be 3%. Out of 400 animals tested, 90 were cattle and 310 were buffaloes. Only buffaloes showed hypersensitivity reaction to tuberculin. None of the cows tested came out to be tuberculin positive. In this particular study, the prevalence of TB on the basis of tuberculin test in buffalo was 2.9% where as in cattle it was 0%. When milk was collected and processed from the above mentioned nine (9) animals, the results showed a different picture. None of the cultures showed any signs of growth by 8 weeks of incubation. All nine milk samples after cleaning were stained by ZN staining and observed under microscope for the presence of mycobacterium, none came out positive.
The Basic Health Units (BHU) in each of the colony were contacted and it was found that in the last 10 years less than 10 patients who were suspected to have tuberculosis were referred to District Health Quarter (DHQ).
Even though a higher percentage (44.44%) of farmers in Harbanspura was recorded to have some knowledge about the zoonotic aspect of tuberculosis as compare to those in Rakhchandra (22.22%), yet a higher number of tuberculin positive animals was found in Harbanspura (6 versus 3). The economic status of farmers in Harbanspura was comparatively higher with 33.33% of farmers earning more than 1 lakh rupees per month, whereas in Rakhchandra this figure stood at 27.78%. This might be a mere chance of co-incidence but it also implies the unwillingness of farmers to apply biosecurity measures at their farms. Lack of willingness to take such precautionary steps places the farmers and their animals in great peril, since in the last six months alone 66.67% of the farmers in Harbanspura had purchased at least one animal, which is enough to bring disease in an un-infected herd. Only 27.78% of farmers in Rakhchandra had purchased animals on the other hand. Also only 77.78% of farmers in Harbanspura would clean the dung from the farms twice a day whereas 100% Rakhchandra farmers would cleanup twice a day. The tuberculin positive animals were found to be spending most time of their day in filthy places. Their sheds were not cleaned regularly. Heaps of dung and ground wet with urine was observed on every visit. It exposed animals to numerous infections and 11.11% of animals in Harbanspura and 44.44% of animals in Rakhchandra were suffering from unidentified chronic illnesses. Farmers said that they preferred to sell such animals to butchers (85.8% combined percentage), rather than burying after culling (3.7% combined percentage). Deworming was not considered a mode of disease prevention amongst the farmers since only 22.22% of all farmers bothered to deworm their animals. The animals were seen to not having a score of above 2.5 when their body scoring was done (Scale 1-5). The one blissful factor discovered was the habit of nearly all farmers (92.59%) preferred to boil milk before consumption. Even dairy products were made from boiled milk (81.48%). This single factor could be the reason why the farmers consuming otherwise contaminated milk was still in such a glowing healthy condition.
The study allowed us to get a measure of the status of disease in lactating animals and to investigate the conditions that prevail in the two dairy colonies. It showed a difference in the prevalence of disease in Harbanspura and Rakhchandra famous for providing milk to Lahore city. This was scrutinized through a detailed analysis of farmer habits and environment of animals in both the fields. This study would permit upcoming researchers to have an up-to-date status of tuberculosis in the dairy colonies.

Publisher: 2015Dissertation note: Paramphistomes are the parasites in the rumen, reticulum, duodenum and liver of goats, sheep, cattle and buffaloes. Their premature stages are in duodenum and then traveled towards the rumen. The damage caused by this illness in bovine affects production. These parasites aggravate a loss of weight, a lower nutritious conversion and a reduce in milk production. Lahore is one of the larger district in the Punjab province of Pakistan. The present study was conducted in order to implement efforts and regulation to eradicate the spread of disease in this area. From this study it was evaluated the changes in hematological parameters values of Large Ruminants and evaluated the Histopathological changes in rumen, reticulum, duodenum and liver.
Samples of blood and tissues were collected at slaughter house from cattle and buffaloes after slaughtering. These were divided into three groups i.e group-A (Infected Buffaloes=50), group-B (Infected Cattle=50) and group-C (Buffaloes, Cattle=20) serve as control. The blood samples and tissue samples of rumen, reticulum, duodenum and liver were taken from infected cattle and buffalo tested positive by fecal examination through direct smear technique and was processed for hematological and histopathological examination.
The infected cattle and buffaloes in this study described a highly significant decrease (p<0.05) in the mean red blood cells, packed cell volume, total erythrocyte count and hemoglobin. There was a significant increase (p<0.05) in the neutrophils number and eosinophil number of disease buffaloes and cows as compared to the non-infected buffaloes and cows. The infection of paramphistomum cervi is characterized by severe anemia, eosinophilia, neutrophilia. Anemia can be responsible for mortality in cattle and buffaloes especially young ones.
Pathological changes were observed grossly and confirmed histopathologically in the rumen, reticulum, duodenum and liver. Pathological changes were mostly limited to small intestine, especially duodenum. The disease caused by the parasite in the rumen was increased cornification of the stratum corneum, atrophy, severe infiltration and thickening of mucosa occurs in the rumen papillae, but no ulceration was found. Changes varied from a localized enteritis and villous atrophy in the duodenum in light disease to severe destructions of the mucosa extending into most of the jejunum in heavy infections. Mucosa at places was found congested with petechial haemorrhages. The histopathological analysis of the diseased liver of buffalos and cows has described that severe harm has occurred in this infection. In most of the sections, the normal structure of liver tissue, arrangement of hepatocyte cords, veins and portal tube areas were undergone clear with full bile ducts indicating bile duct hyperplasia, necrosis of liver tissue and cause necrosis. The immature forms of Paramphistomium cervi caused more severe damage in the duodenal tissue, where as adult forms inflicted mild tissue damage in the rumen.
The present study was conducted in order to implement efforts and regulation to eradicate the spread of disease in this area. From this study it was evaluated the changes in hematological parameters values of Large Ruminants and evaluated the Histopathological changes in rumen, reticulum, duodenum and liver.

Publisher: 2015Dissertation note: Zinc is a component of about three hundred enzymes of all six enzyme classes. Zinc oxide nano particles (ZNOPs) improve the antioxidant status of broilers. By using ZNOPs, the bioavailability increases due to its smallest size and large surface area. Up to the best of our knowledge, no research work has been conducted on supplementation of ZNOPs in poultry in Pakistan and very little has been documented worldwide.
ZNOPs improve the anti-oxidant health status of broilers at low concentrations compared with bulk zinc oxide.
The study was consist of 100 day-old broiler chicks and randomly divided into 4 groups, each group consists of five replicates (n= 5 in each replicate). Group A was control fed with basal diet (BD) only, Group B was supplemented with 80 mg ZnO/kg BD, Group C and D was supplemented with 40 and 80 mg ZNOPs/kg BD respectively for 35 days. The parameters were delayed type hyper sensitivity, malondialdehyde, glucose, total protein, albumin, globulin, triiodothyronine, thyroxin, creatinine, bilirubin, urea and uric acid.
Statistical analysis was conducted with Statistical Packages for Social Sciences (SPSS version 20 USA). The data was analyzed using one way ANOVA.
The results of serum glucose concentration was found significantly higher (P < 0.05) in Group B and Group C compared to the Group A but was found similar to Group D Delayed type hyper sensitivity, Serum Anti-oxidant status, Serum Proteins, Serum
thyroid hormone level, Kidney Function Tests, Serum Bilirubin Concentration were found non-significant (P < 0.05) in all the groups compared to the control group.
ZNOPs do not cause nephrotoxicity hence they are safe for kidney .These particles does not disturb the thyroid hormones. However their antioxidant and protein effects were not observed in our study. That could be due to low dose of ZNOPs. Availability: Items available for loan: UVAS Library [Call number: 2412-T] (1).

Publisher: 2015Dissertation note: Diabetes mellitus is most common disorder affecting almost 25% of the world's population. Many researchers reported the role of metals in glucose metabolism and their defficiency cause the diabetes. Zn is found in all cells of body and play role to maintain blood sugar level and in the synthesis, storage, and secretion of insulin. Zn supplementation shows protective effect on total lipid, cholesterol, HDL and atherogenic index. Nanotechnology affects on the all parts of human life, animal, environment, and industrial life. In the present study I evaluate the anti-diabetic activity of ZnONPs and also the dose dependent anti-diabetic effects of medicine in alloxan induced diabetic rats.
Twenty five adult male rats were divided into five groups; Negative control, Positive control, and 3 groups for different treatment dose of ZnONPs (15 mg/kg BW), ZnONPs (25mg/kg BW) and ZnONPs (50 mg/kg BW). Diabetes induction had done in four groups, other than negative control, by subcutaneous administration of alloxan (120 mg/kg BW). Treatment was given to groups for 21 days. BW was recorded weekly. Blood samples were collected from animals of each group on 21 days after induction of diabetes by cardiac puncture to measure serum glucose level, serum lipid profile and liver function test. Data was analyzed by using SPSS software. Data was analyzed by using one-way ANOVA. The group differences were compared by the Duncan’s Multiple Range Test. Differences was considered significant at P < 0.05.
The obtained results showed that ZnONPs has efficiency to control the diabetes mellitus by reducing blood glucose levels as well as the increasing dose decreased the serum glucose level. Only ZnONPs 50mg/kg BW dose is efficient to reduce the muscle wastage due to diabetes in alloxan induce diabetic rats. This dose also works to maintain the serum ALT, TG, HDL-C, LDL-C levels. But this dose is not effective for body weight, AST, ALP, VLDL-C, cholesterol and AI.
The data obtained from this study also showed the dose dependent anti-diabetic activity of medicine as the dose of 50mg/kg BW is more effective to control the diabetes as compared to other two doses; 15mg/kg BW and 25mg/kg BW.

Publisher: 2016Dissertation note: Endocrine disruptors (EDs) are exogenous compounds present worldwide. Endocrine hormone production, release, transport, binding, action or elimination is enhanced or interrupted by EDs and hence affect homeostasis, development, reproduction and behaviour of organisms. Bisphenol A (BPA) is one of the most important EDs used extensively in consumer products such as beverage, food can lining, dental sealants and thermal paper and water pipes. BPA binds to estrogen receptors and enhance or interrupt the endocrine system. BPA have negative effectson bone health and serum minerals in rats.
A total of 48 adult rats were divided in three main groups i.e. (16 rats in each group). Each group was sub-divided into male (8 rats) and female (8rats). Control Group: Basal rat diet was provided to control group. Group A: BPA 1mg/kg body weight daily along with basal rat diet was given to group A. BPA was dissolved in 10 % ethanol and was diluted with distilled water. Group B: BPA 0.1mg/kg body weight daily along with basal rat diet was given to Group B. BPA was dissolved in 10 % ethanol and was diluted with distilled water. Trial duration was 3 months and at the end rats were killed to obtain the bones and muscles to observe their bone characteristics (bone length, width, and medullary canal diameter) and serum minerals (Zn, Fe, Cu and Ca) analysis.Data wasanalysed using two ways ANOVA through SPSS version (SPSS Inc. version 20, Chicago, Illinois) and was presented as mean± SEM.
Femur bone length was found to be significantly higher in male rats treated with BPA 0.1mg/kg and 1mg/kg compared to control. The femur bone length was not affected in female rats. Rest of the parameters in bone health of tibia and femur were not affected by treatment. Bone minerals (Ca, Cu, Fe, and Zn) were also not affected by the treatment irrespective of treatments.Serum calcium was significantly higher in mal rates treated with 1mg/kg BPA compared to control; whereas it decreased significantly in female rats treated with 1mg/kg BPA compared to control. Serum zinc concentrations also decreased significantly in female rats treated with BPA 1mg/kg compared to control. Muscle copper concentration was significantly higher in male rats treated with 1mg/kg BPA compared to control. Iron muscle concentration was significantly increased in male and female rats treated with 1mg/kg BPA compared to control. Muscle calcium concentration was significantly decreased in male rats treated with 1mg/kg BPA compared to control.

Publisher: 2016Dissertation note: Methotrexate (MTX) is an antifolate drug which is used to treat a variety of Autoimmune Diseases e.g rheumatoid arthritis, psoriasis and different types of cancers. However, MTX toxicity limit its use which include oxidative stress in causing toxicity on the liver, kidney, heart and other organs.Montelukast is a leukotriene antagonist.Recent evidence suggests that montelukast possessesantioxidant and anti-inflammatoryactivity.Thirty (n=30) adult albino ratswere selected and housed in stainless steel cages in the Experimental Animal shed, Department of Physiology, University of Veterinary and Animal Sciences, Lahore. The rats were randomly divided into five groups having six rats in each group. Animals were treated by following treatment plan;
Group 1: (Negative Control) injected I/P with physiological saline from day zero to day four and then injected with 2 % ethanol from day four to day ten.
Group 2: (MK positive control) injected I/P with MK (10mg/kg body weight, BW) from day four to day ten for consective seven days.
Group 3:(MTX positive control) injected at day zero I/P with a single dose of MTX (20mg/kg BW) per ten days.
Group 4:(MTX-MK 5) injected at day zero I/P with a single dose of MTX (20mg/kg BW) and then injected I/P with MK (5mg/kg BW) from day four to day ten for consective seven days.
Group 5: (MTX-MK 10) injected at day zero I/P with a single dose of MTX (20mg/kg BW) and then injected I/P with MK (10mg/kg BW) from day four to day ten for consective seven days.
Data was analyzed by one way analysis of variance using SPSS software (SPSS Inc. version 20, Chicago, Illinois). The group differences werestudied by using Duncan’s multiple range tests. The P value <0.05 was considered as significant. Data was presented as mean ± SD. Body weight and feed intake was analyzed by using repeated measure analysis.
The current study showed reduction in feed and water intake and shows diarrhea like symptoms which ultimately results in gradual reduction in body weight in MTX treated groups when compared with control group. While non MTX treated groups shows increase in feed consumption and ultimately increase in body weight. BUN and creatinine level were increased after MTX administration which was reduced after MK treatment. MK10mg/kg BW dose administered to G5 after MTX was more effective compared to 5mg/kg BW dose of MK administered to G4 after MTX treatment. Enzymatic level of MDA and catalase in serum, liver and kidney tissue were increased after MTX administration in G3, G4 and G5.There was no highly significant results found after MK treatment due to Low dose of MK which was unable to maintain the enzymatic level after induction of imbalance between oxidant and antioxidant level.
Conclusion: From our study we have concluded that montelukast administration after methotrexate induced toxic effect on renal function test and hematological parameters, it can significantly normalize the level of BUN and creatinine also shows significant improvement in Hb and RBCs level. While there was no significant effect found on oxidative stress due to insufficient dose of MK.

Publisher: 2016Dissertation note: Cats are commonly known as friendly companion of man. The cat is domesticated pet animal and has been widely kept as companion. Feline scabies is one of the most common and severe skin diseases of cats, caused by sarcoptic mange. Despite the high prevalence and severity of the disease, many aspects of feline scabies remain poorly understood. In addition, to the best of our knowledge, the study on cat scabies is limited in Pakistan.
A total of 214 cats were examined of these 96 (44.9%) were positive for sorcoptic mange it was observed that mange infestation was highest in cats under 1 year and above 2 year of age. Whereas the lowest in 1.5 year of age cats. As regard the sex wise prevalence of mange infestation it was high in female cats than males.
The samples were taken from the suspected cats having some skin problem irrespective of breed, sex or age, from Pet Center UVAS Lahore and Private clinics. After confirmation of the disease by skin scrapping test and identification through morphological standards, 5 ml blood was collected from the jugular vein of cat in a clean test tube containing a few drops of 1% EDTA as anticoagulant. Then these test tubes were labeled with specific number to each blood sample along with date of collection and hematological and serological studies were undertaken on the samples. The cats were divided into two groups (Group A and B) for treatment trial, each group will consist of further 4 groups, each group containing 4 cats and 16 cats in each group. Group A was treated with the Ivermectin 0.04mg/kg BW s/c on every week for consecutive 4 weeks. Group B was treated with Doramectin s/c 0.6mg/kg BW on every week for consecutive 4 weeks. To evaluate the effectiveness of a particular treatment, skin

scrapings were collected from each treated cat at 0 day before treatment and at 7th, 14th, 21st and 28th day post-treatment. But blood samples were analyzed at 0 day, 14th, 28th day, subjected to hematocrit, Hb, counting of red blood cells (RBCs) and white blood cells (WBCs), and differential leukocytes count RFT (blood urea Nitrogen, Creatinine), LFT (ALT, AST, ALP, Total Bilirubin).
Out of 214 the positive cats for the Scabies were 96 so the overall infestation rate was 44.9% in cats. The cat scabies is mostly occur in more than 24month age of cats and on secondly age group was 07-12month. For therapeutic trail 32 cats were brought into clinical trial , each clinical score contains four cats and total 32 cats have been divided into 2 groups viz. Group A(Ivermectin) and Group B(Doramectin). In group A ivermectin 0.4mg/kg B.W S/C weekly for continuous four weeks. In group B Doramectin 0.6mg/kg B.W S/C weekly for continuous four weeks. There was no change in WBCs, significant increase in RBCs, also increase in creatinine, but significant decrease in ALT, ALP, Bilirubin, and BUN. There was no change in AST.
After four weeks of treatment trail ivermectin have better reduction rate of parasite. The ratio of pet animal was very less as compared to stray cats as the stray animal have no barrier to control the spread of disease. The percentage of previously infected and then cured animal or having disease history is less than that of newly infacted cats. This study proposed that the hospital acquired infection were more, the reason may be the contaminated clinical utensils or attendant’s hands. Scabies is the disease which spreads more in those animals which were in grouping as compared to randomly moving cats and very less in individual cats. Scabies is one of the most possible contact diseases. The more the contact more will be the chance of disease occurrence. The number of cats and percentage was very less of primary flea infestation, in the consequence of scabies infection. The fungal infection also existed at the same time of scabies

Publisher: 2016Dissertation note: Tuberculosis (TB) is a common and fatal infectious disease which has afflicted mankind for several millennia. At the moment, TB is positioned at number five when it comes to the most common causes of fatality worldwide. TB is curable if it is properly diagnosed and treated. In 2015, it was estimated that 1.5 million deaths (an equivalent of 4,000 deaths per day) and 9 million new TB cases have been reported. Diabetes Mellitus is also widely distributed and estimated to affect 366 million people by 2030. The co-morbidity of DM and TB is re-emerging because of the progressive epidemiology of both diseases especially in the developing countries. Endemicity of TB and DM is growing in developing countries because of low socio-economic status and poor living conditions.
In this study, a total of 500 tuberculosis positive patients were selected under TB DOTS program from five tertiary care hospitals of Lahore. Sputum samples were collected from all the enrolled patients and smear microscopy was performed for TB confirmation. Blood samples were collected from the same patients for screening of diabetes mellitus. Sputum samples were also processed for culture and drug sensitivity on LJ medium. Molecular identification by PCR technique was carried out on all positive cultured strains and results were compared with reference strain H37RV. For DNA sequencing, PCR products were sent to Singapore where sequencing was performed by Sanger method.
Data was compiled and variables including gender, age, drug resistance and treatment history and correlation among different variables was analyzed using chi-square test and Fischer’s exact test method at P-value of ≤0.05. SPSS (Statistical Package for Social Sciences, Version 20.0) was used for statistical analysis. The count data was statistically analyzed using

descriptive statistical tools. On screening for fasting blood sugar level, 74 (14.8%) patients were recorded as diabetics as well i.e. blood sugar level ≥ 126 mg/dl. Out of these 74 patients, 22 patients had previous history of diabetes whereas remaining 52 patients were newly diagnosed at the time of screening. The maximum distribution of TB-DM patients was found in age group > 57 years. Mean age of the group without DM was 39 years and with DM was 48 years. Coexistence of DM in TB patients was higher in males (62.2%) as compared to female study subjects. However, the gender difference is statistically non-significant (p value 0.243).
The distribution of education level revealed that out of the total participants, maximum number of patients (n=220) were illiterate and similar trend was observed in diabetic patients with 54 (73%) individuals belonging to the illiterate group of the subjects. There is statistically significant difference between existence of DM and literacy level in tuberculosis patients. Among social and behavioral risk factors in tuberculosis patients, majority of the patients were unemployed (24%) in TB-DM group. Significant correlation p value ≤ 0.05 was found between coexistence of TB-DM and tobacco use. TB cases with diabetes were known to have history of smoking with 73% (n=54) while non-smokers were 27% (n=20).
On sputum smear microscopy frequency of 3+ results showing high bacterial load, was profoundly higher i.e. 67.6% in diabetic tuberculosis patients as compared to non-diabetics which was 4.9% only. Total culture yield was 363 out of 500 sputum samples. There were 193 samples that were sensitive to all drugs, 9.4% were MDR strains (resistant to Isoniazid and Rifampicin). MDR-TB is significantly higher in TB-DM patients i.e. 13.5% as compared to 8.7% in TB only patients.
In our study, DNA sequence data for drug resistance was studied by the sequence of rpoB gene of the wild type MTB strain. Sequencing results showed mutations at various spots of rpoB gene.
SUMMARY
125
Most common mutational sites identified were at codon 531, 526 and 516 with frequency of 70%, 15% and 7.5%, respectively. Moreover, mutation sites at 512 and 574 codon had also been reported. In this study, predominantly two phylogenetic variants were identified. Majority of the isolated strains were Central Asia Strain (CAS) with a prevalence of 88.2% and rest were Beijing strain. However, attempts to find zoonosis could not be established. A total of 900 raw milk samples were also screened for M. bovis and no positive sample could be detected.
The present study emphasizes the importance of screening for DM in TB patients, which had not been done in routine. This practice may prove to be helpful in reducing the disease burden of TB patients as well as DM patients. Thus it is recommended that the screening for DM should be implemented in TB/DOTS clinics.
Emergence of Multi drug resistant Mycobacterium tuberculosis is also a serious challenge for clinicians. A very large financial implication in terms of treatment, duration of chemotherapy and spread of MDR TB strains is being faced. Treating MDR TB is more complicated than treating drug sensitive TB. Patients with MDR TB require longer, much more costly treatment and experience higher mortality rates. Such a long time to initiate the treatment is not affordable, thus there is a dire need for some rapid technique like molecular based diagnostics for MDR detection, which can provide quick results and making it possible to start treatment at earlier to minimize transmission, morbidity and mortality.

Publisher: 2016Dissertation note: Deep-fat frying of foods is the most common and quickest method in food preparation. Numerous chemical changes occur during heating process of oils, which promotes the production of different volatile and non-volatile compounds. These noxious compounds are absorbed in the food, and ultimately enter the systemic circulation after digestion and absorption. Effects of peroxidation of biological systems come with a number of pathological manifestations including incidence of oxidative stress, glucose intolerance and atherosclerosis.
Repeatedly heated cooking oil consumption has harmful effects on anthropometric characteristics, lipid profile in male and female rats.
Thirty six adult male and female Wistar rats were selected and divided into six groups having three groups of male rats and three groups of female rats. Group-I including IA (negative control males) and IB (negative control females) were fed chow diet. Group-II including IIA and IIB were given chow diet mixed with 15% v/w fresh oil. Animals in sub-groups IIIA and IIIB were fed on chow diet mixed with 15% v/w fried oil. Body weights were recorded weekly. Organs and blood samples were collected at the end of 28 days to assess organ weights, measure plasma glucose level and lipid profile.
Data was analyzed using SPSS software. Data was analyzed using two-way ANOVA. The group differences were compared by Tukey’s range test. Differences were considered significant at P < 0.05.
Body length of rats was not significantly affected by the feeding of single and multiple fried oil. Effects of treatment, gender and week are significant on body weights of rats. Effect of single and multiple fried oil feeding was significant on absolute weights of abdominal fat and

One of them is heat stress which has marked damaging effect on the normal physiology of an individual. Moringa oleifera is a versatile plant from Moringaceae family. Moringa oleifera is a best food plant but it also has a large potential as a medicinal plant. Due to rich source of flavonoids, Beta- carotenes, vitamin A & D, Moringa oleifera is known as a best natural anti-oxidant. The leaves of Moringa oleifera also possess hepato-protective and renal protective activities due to its rich anti-oxidant potential.
Hypothesis:It was hypothesized that Moringa oleifera leaf powder supplementation will ameliorate the redox status, hepatic and kidney function in rats exposed to heat stress.
Methodology: Adult male wistar rats (n= 24) were procured and housed in stainless steel cages in the experimental animal shed of department of Physiology, University of Veterinary and Animal Sciences, Lahore-Pakistan. After acclimatization, rats were divided in to four groups (One control and 3 MOLP treated groups). Rats were exposed to high environmental temperature (37±1°C ) for one hour daily(12.00 PM-1.00 PM) throughout the experimental period of 21 days for the induction of heat stress(Sinha. 2007). Anti-stress properties of Moringa oleifera leaf powderwere examined by measuring biochemical parameters, i.e. redox by estimating serum malondialdehyde through assay used by(Ohkawa et al. 1979) and catalase by the same spectrophotometric protocol in accordance with the study (Hadwan et al. 2016).

Publisher: 2017Dissertation note: Animal products such as meat and milk are the primary source of proteins and amino acid that can be produced throughout the year. Diseases in animals initiate the biophysical and socio economic impact that varies from localized to global. Different pathogens including virus, bacteria and fungi cause different diseases in ruminants. Escherichia coli are one of the inhabitants of intestinal tract and are responsible for watery diarrhea, bloody diarrhea and hemorrhagic colitis. Diarrheal disease gives rise to global health problem and now a day many plants are used to treat the disease condition. Catharanthus roseusis one of the important medicinal plants used for the treatment of many diseases such as diarrheal, diabetics, wound healing and Alzheimer’s disease. C. roseus maintain the optimum performance of gut barrier by reducing the loss of minerals. The changes in the electrophysiology of jejunum with the addition of C.rouses were measured by Ussing chamber. Objective of this study was to investigate the effects of C.roseus on the barrier function of intestine influenced by E. coli.
Catharanthus roseus may reduce the detrimental effects induced by E.coli and improves the gut barrier function.
Five buffalos of uniform age and weight were selected and slaughter at local slaughter house. Jejunum was taken from the intestinal part and rinsed with standard buffer. Serosal layer was removed and tissue was mounted in using chamber. After incubation period of 15-20 mins different groups were treated with different treatments. Control with no treatment, group B was treated with 10% toxin of E.coli, group C was treated with 1.5% extract of C.rouses, group D was treated with 10% toxin of E.coli and 1.5% extract of C.rouses. After treatment the electrophysiological parameters like Isc and Gt was observed.
C.rouses affected the electrophysiology of isolated jejunum of buffalos by decreasing the short circuit current which was induced by the E.coli toxin. The decrease of current between the groups is significant (p value < 0.05). ΔIscwas also significant between the groups containing E. coli toxin and C. roseus containing solution. Conductance increased significantly after the addition of E. coli and C. roseus (p value < 0.05).
Data were analyzed by using completely randomized ANOVA followed by post-hoc Duncan’s multiple range tests. Level of significance was set at 0.05.
Catharanthus roseus treatment affects the electrophysiological indices of isolated jejunum epithelium of buffalos presumably by closing the chloride channels and enhances the ions absorption across the jejunum epithelium. This may leads to efficient mineral utilization and better health of animals.

Publisher: 2017Dissertation note: Bisphenol A is an endocrine disruptor. It is monomer of polystyrene and a basic component of epoxy resins. It is carcinogenic in nature and has adverse impact on health of different animals as wells as human beings. It harms the reproductive, renal system as well as a basic reason of metabolic syndrome. The aim of this study is to assess the effect of sub chronic exposure of Bisphenol A on anthropometric parameters and lipid profile in rats
Bisphenol A may elevate serum lipid profile level and increase the ratio of anthropometric parameters in rats.
Forty eight albino rats half male and half females of similar age and weight were selected. They were divided into three groups each having sixteen rats in each (8 males,8 females) and named as Group A, B and C for experimental trial of three months. Group A was referred as control group treated with only basal diet and water. Group B was treated with 0.1mg/kg (body weight) BPA with basal diet and water. Group C was treated with 1mg/kg (body weight) BPA with basal diet and water. After three months blood sample was collected by euthanizing the rats to obtain serum sample for biochemical analysis and at the same time anthropometric values were noted.
Data was analyzed via two way ANOVA using SPSS software and Post hocTukey test was applied to study and compare differences between the groups. The p value <0.05 was assumed as significant value.
At the end of this trialour studies suggest thatthe effect of Bisphenol A increased the ratio of anthropometric parameters up to a certain limit as well as it significantly effects the all nutritional parameters. It highly effectsthe concentration of HDL in serum lipid profile.
It disturbs the concentration of ALP and AST at low doses while ALT had no significant effects due to BPA. It had no significant influences on kidney metabolites e.g., creatinine urea and BUN. Glucose concentrationalso not showed any profound effect in male and female albino rats.

Publisher: 2017Dissertation note: Hypercholesterolemia is characterized by higher level of bad cholesterol in blood which shoots up the risk factor for cardiovascular diseases, hyperlipidemia, oxidative stress, weight gain and other metabolic disorders. Modern way of life is the reason to elevate these metabolic syndromes that lead to increased mortality rate. Psyllium husk is helpful in improving anthropometric parameters, high lipid profile, glucose level, appetite, oxidative status, hypertension and maintains liver and renal physiology. The effective use of this drug was for weight loss to control obesity.
The consumption of psyllium husk may lead to hypocholesterolemia, reduced body weight, oxidative stress and biological profile in rats. Twenty four male Wistar rats were taken and divided into four groups. Group-I (negative control) fed chow diet Group-II (positive control) was given chow diet mixed with 10g cholesterol for 42 days. Group-III (treatment group) hypercholesterolemic rats were fed with 5g psyllium husk for 21 days. Group-IV (treatment group) hypercholesterolemic rats were fed with 10g psyllium husk for 21 days. Blood samples were collected at the end of six weeks of study. Anthropometric parameters, organs weight, Lipid profile (TC, TC, LDL, HDL, Atherogenic index), glucose, oxidant and antioxidant levels, electrolytes, hepatic (AST, ALT) and renal (blood urea nitrogen, urea) functions (in blood liver and kidney) were studied. Data were analyzed using one way ANOVA on SPSS. Differences between the groups were compared by Duncan’s Multiple Range Test. Differences were considered significant at P < 0.05.
Anthropometric measurements, organs weight, lipid profile, glucose,urea and blood urea nitrogen showed significantly results, while,TG, atherogenic index ,electrolytes, oxidant and anti-oxidant ALT and AST showed no significantly values.

Publisher: 2017Dissertation note: Endocrine disruptors (EDs) are exogenous compounds present worldwide. Endocrine hormone production, release, transport, binding, action or elimination is enhanced or interrupted by EDs and hence affect homeostasis, development, reproduction and behavior of organisms. Dibutyl phthalate (DBP) is one of the most important EDs used extensively in consumer products such as plasticizers, nail polish, paints, thermal paper and water pipes. DBP binds to estrogen receptors and enhance or interrupt the endocrine system. DBP have negative effects on bone health and serum minerals in rats. A total of 48 adult rats were divided in three main groups i.e. (16 rats in each group). Each group was sub-divided into male (8 rats) and female (8rats). Control Group: Basal rat diet was provided to control group. Group A: DBP 10mg/kg body weight daily along with basal rat diet was given to group A. DBP was dissolved in 10 % ethanol and was diluted with distilled water. Group B: DBP 50mg/kg body weight daily along with basal rat diet was given to Group B. DBP was dissolved in 10 % ethanol and was diluted with distilled water. Trial duration was 3 months and at the end rats were killed to obtain the bones, serum and muscles to observe their bone characteristics (bone length, width, and medullary canal diameter) and minerals (Zn, Fe, Cu and Ca) analysis. Data was analyzed using two-way ANOVA through SPSS version (SPSS Inc. version 20, Chicago, Illinois) and was presented as mean± SEM.
Femur bone length was found to be significantly higher in male rats treated with DBP 10mg/kg and 50mg/kg compared to control. The femur bone length was not affected in female rats. Rest of the parameters in bone health of tibia and femur were not affected by treatment. Bone minerals (Ca, Cu, Fe, and Zn) were also not affected by the treatment irrespective of treatments. Serum calcium was significantly higher in male rates treated with 50mg/kg DBP

compared to control; whereas it is decreased significantly in female rats treated with 50mg/kg DBP compared to control. Serum zinc concentrations also decreased significantly in female rats treated with DBP 50mg/kg compared to control. Muscle copper concentration was significantly higher in male rats treated with 50mg/kg DBP compared to control. Iron muscle concentration was significantly increased in male and female rats treated with 50mg/kg DBP compared to control. Muscle calcium concentration was significantly decreased in male rats treated with 50mg/kg DBP compared to control. Availability: Items available for loan: UVAS Library [Call number: 2896-T] (1).
