ThesisItem Open Access Clinical Studies Of Various Eye Affections Of Dogs(Guru Angad Dev Veterinary and Animal Sciences University, Ludhiana, 2001) Gurpreet Singh Bath; Kirti DuaIn the present study, incidence, diagnosis and treatment of various eye affections of the dogs were studied. It was observed that eye affections were more common in old age dogs. In a total number of 67 eye affections, conjunctivitis and cataract were the most prevalent. The incidence of conjunctivitis and cataract was more in male dogs. All cases of conjunctivitis and keratoconjunctivitis in the present study were bilateral and associated with dermatitis and otitis in most of the cases. In ulcerative keratitis, supplementation of vitamin A helped in early recovery. Chronic epiphora which was due to obstruction of nasolacrimal system was observed mostly in the Spitz breed of dogs. Glaucoma was observed only in female dogs with mean age of onset being 7.5 ± 0.9 years. The intraocular pressure (10P) in glaucoma eyes recorded was higher ( > 35 mmHg) as compared to the 10P of normal healthy eye (mean 27.95 mmHg). Glaucoma was also observed secondary to cataract and the mean age of onset of cataract in the present study was 9.7 ± 0.9 years. Microbiological evaluation revealed Staphylococcus aureus from the conjunctiva in most of the eyes and Streptococcus spp. in other few eyes. These bacterial isolates were sensitive to gentamicin and chloramphenicol in all cases with varying sensitivity to norfloxacin, enrofloxacin, tetracycline, ampicillin and cloxacillin. Haematological values were within normal range in almost all the cases. Other eye affections observed were heterochromia iridis, cystic swelling of third eyelid, hyperplasia of nictitans gland, squamous cell carcinoma of eyelid, persistent pupillary membrane, retinal detachment and panophthalmitis.ThesisItem Open Access Clinico-Biochemical And Therapeutic Studies Associated With Gastroenteritis In Dogs(Guru Angad Dev Veterinary and Animal Sciences University, Ludhiana, 1997) Malvinder Kaur Sidhu; Kirti DuaThe study was conducted Dn the clinical cases of haemorrhagic gastroenteritis in dogs presented at PAU Small Animal Clinics. The unvaccinated dogs of all breeds were susceptible but maximum were of Spitz breed. The pups of 2-4 months were most susceptible to gastroenteritis. Although no specific reason is known but the susceptibility of the male dogs was more than the females. Anorexia, depression, vomition (watery to blood stained) and bloody diarrhoea were the initial signs which lead to dehydration, increased total proteins and packed cell volume. The other clinical signs were fever increased heart rate and pulse rate. The dogs showing symptoms of gastroenteritis were anemic and exhibited hyponatremia, hypokalemia and hypochloremia. Following the treatment the status of plasma sodium, potassium and chloride improved. Therapy trials were conducted in dogs suffering from haemorrhagic gastroenteritis. Oral feeding and medication was avoided. Vigorous fluid and electrolyte therapy along with antiemetic was administered. To check the secondary bacterial infection a third generation cephalosporin i.e. cefotaxime was given @ 10 mg/kg b.wt. IM (repeated at 12 hour interval) and the disposition kinetics was studied. The plasma concentration of cefotaxime in healthy animals of control group was in the range of 0.38-0.75 ?g/ml and in affected animals blood concentration of cefotaxime was less than 0.84 ?g/ml. The decreased level of blood concentration of cefotaxime observed in present study could be due to rapid excretion of drug owing to continuous fluid therapy. Hepatocellular injury as indicated by increased plasma level of SGPT and ALP also might have altered the disposition of cefotaxime as its metabolized in liver. In group III of affected animals lignocaine @ 50 ?g/kg/min in continuous infusion was tried as analgesic as the therapeutic effect of it is replacement of strong stimuli by regenerative and reparative one. In group IV of affected animals metronidazole was administered @ 7.5 mg/kg IV in order to check anaerobes. There was hundred per Cent recovery in all the groups of affected animals which suggests MIC of cefotaxime was maintained. However, the quickest recovery was observed in animals of group IIIThesisItem Open Access Study On Role Of Sodium In Production And Health Of Cattle And Buffalo(Guru Angad Dev Veterinary and Animal Sciences University, Ludhiana, 2004) Amrit Singh Gajebasia; Kirti DuaSodium is a macro mineral highly essential for life. The present study was conducted to assess the sodium status in urine and saliva and to assess the relationship of sodium depletion on production of dairy animals. The study was conducted on 204 dairy animals which included 126 buffaloes and buffalo heifers and 78 cows and cow heifers. Sodium and potassium concentrations were estimated in urine, saliva and plasma using flame photo -meter. It was observed that lactating buffaloes were having higher urinary sodium concentration as compared to dry buffaloes. In cows, the salivary sodium concentration was on higher side in lactating cows as compared to dry cows. The urinary sodium concentration was on higher side in the animals of organized farms. The urinary potassium concentration in all the groups of buffaloes and cows was significantly higher than the salivary potassium concentration and it remained higher in the animals of both organized and unorganized farms during summer and winter seasons. The salivary sodium to potassium ratio was significantly higher than the urinary sodium to potassium ratio at organized and unorganized farms during summer and winter season in both buffaloes and cows. The trend of increased sodium to potassium ratio in saliva as compared to urine remained same in sodium supplemented animals. After salt supplementation the changes were more prominent in saliva, so it can be inferred that saliva is a better indicator of sodium status in body. In saliva, the sodium concentration was in normal limits but potassium concentration was on higher side resulting in low sodium to potassium ratio. While comparing buffaloes and cows, it was observed that salivary sodium to potassium ratio was on higher side in cows and their heifers than buffaloes and their heifers.
