    Pathology of the prostate gland in dogs
    (Centre of Excellence in Pathology, College of Veterinary and Animal Sciences,Mannuthy, 2004) Dhanya Menon, KAU; Vijayan, N
    The present investigation was undertaken to evaluate the prevalence and nature of pathological conditions of the canine prostate. A detailed systematic examination of 100 carcasses brought for autopsy during the period of investigation was conducted and the gross and histopathological lesions were studied in detail. The study confirmed prostatic disorders as an age related problem and also warned that involvement of the prostate in concurrent pathological affections of the urogenital system should not be overlooked. Heavy breeds like the German shepherds were found to be the most susceptible to prostatic diseases. An age related increase was also seen in the prostatic weight, circumference and length. Prostatic lesions could be encountered in 49 per cent of the cases. The most common prostatic disease encountered in this study was benign prostatic hyperplasia followed by prostatitis, prostatic atrophy, prostatic adenocarcinoma and squamous metaplasia. Glandular, cystic and complex types of hyperplasia could be observed. The identification of prostatic adenocarcinoma in a castrated dog pointed to the necessity to study the role of extra gonadal sex hormones in prostate carcinogenesis. Escherichia coli and Klebsiella sp. were isolated from cases of prostatitis. Acid phosphatase activity was more for hyperplastic and neoplastic prostates when compared to the normal prostate. This indicated that prostatic acid phosphatase could be used as a marker for the diagnosis of canine prostate cancer both by impression smears and cryostat sections.

    Pathology of cardiac disorders In cattle
    (Centre of Excellence in Pathology, College of Veterinary and Animal Sciences, Mannuthy, 2002) Bisi, T V; KAU; Sreekumaran, T
    The present study was undertaken to assess the prevalence and pathology of various cardiac disorders in cattle. The data collected from the autopsy records maintained at the Centre of Excellence in Pathology, Mannuthy and hundred and one samples of heart obtained from both the slaughtered cattle and necropsy cases formed the basis of the study. Fifty five per cent hearts showed lesions of varying type. The highest incidence was for sarcocystosis (45 per cent). Vascular lesion~were present in 33.8 per cent cases. Other myocardial lesions encountered were myocardial degeneration, myocarditis and other cardiomyopathies of unknown etiology. Endocardial fibroelastosis and valvular sclerosis were observed in four cases. Valvular and coronary vessel lesions showed correlation with hypertrophic cardiomyopathy. The incidence of pathological disorders encountered were relatively high. The need and scope for investigation into the pathological disorders of bovine heart were highlightened.
