Abstract:
The study was conducted to elucidate the pathology of miscellaneous conditions i.e. cardiac hypertrophy and atrophy of cardiac muscles related to heart of sheep (Ovis aries). Cardiovascular system was examined with total 587 samples, irrespective of age, breed and sex. Out of these, suspected 147 specimens of heart with pathological abnormalities were processed for histopathological examination. Miscellaneous conditions i.e. cardiac hypertrophy and atrophy of cardiac muscles were recorded in 13 cases with occurrence of 8.84 per cent. In cases of cardiac hypertrophy, grossly, abnormal thickening of heart walls and enlargement of heart were found. On microscopic examination, increased size of cardiocytes in ventricular wall was observed. The sections showed hypertrophied appearance. In case of atrophy of cardiac muscles, macroscopically heart was small in size and necrosed. Microscopically, cardiocytes decreased in size with necrocis of cells and the space between the myocytes increased due to decrease in size of cardiocytes.
