    STUDIES ON OCCURRENCE OF HEPATIC AND PANCREATIC DISORDERS IN DOGS
    (KARNATAKA VETERINARY, ANIMAL AND FISHERIES SCIENCES UNIVERSITY, BIDAR, 2017-12) HARSHITHA, C.R; Dr. M.L. SATYANARAYANA)
    The present investigation was undertaken to study the occurrence of various pathological conditions in the liver and pancreas of dogs that were presented to the Department of Veterinary Pathology, Veterinary College, Bengaluru. Hepatic lesions were found to be highest in dogs of less than one year, of male sex and non-descript breeds. The lesions were histopathologically classified as vascular changes which include congestion (75.71%), haemorrhage (68.57%) and haematoma (1.42%). Degenerative and necrotic changes which included cell swelling (4.28%), hydropic degeneration (17.14%), fatty change (18.57%) and necrosis (20%). Inflammatory changes included hepatitis (17.14%) and cirrhosis (35.71%). Proliferative changes were hyperplasia of hepatocytes (12.85%) and biliary epithelium (27.14%) and neoplasia (2.85%). Miscellaneous conditions were hemosiderin (28.57%), calcium (2.85%) and bile pigment (20%) deposition. Pancreatic lesions were found to be highest among dogs of above 12 years (22.72%), of male sex (54.54%) and non-descript breeds (36.36%). Microscopically, exocrine pancreatic lesions were classified as vascular changes like congestion (56.81%), haemorrhage (25%) and oedema (4.54%). Degenerative and necrotic changes included degeneration of acinar cells (47.72%), parenchymal necrosis (45.45%), pancreatic fat necrosis (4.54%) and acinar calcification (6.81%). Inflammatory changes recorded were acute (6.81%) and chronic pancreatitis (31.81%). Proliferative changes included hyperplasia of acinar cells (6.81%) and neoplasia (15.90%). Endocrine pancreatic lesions were classified as congestion (11.36%), hypocellularity (18.18%), hypercellularity (11.36%), vacuolar degeneration (25%) and neoplasia (2.27%). Thus, this study concluded that large number of cases revealed abnormality upon microscopic than gross examination, suggesting the need for histopathological evaluation to arrive at accurate diagnosis.
