Abstract

The pancreas consists of exocrine and endocrine portions. The work was conducted in six adult dogs of different breeds. The gland was removed cut and fixed in 10 percent neutral buffered formalin and Bouin’s fluid. The normal tissue processing was done and paraffin blocks obtained and was cut into 5-micron thick sections and stained by the H & E technique. The pancreas of a dog is a compound tubulo-alveolar gland. It was surrounded by a loose connective tissue capsule. Connective tissue septa entered into the parenchyma and divided it into many lobes and lobules. Each lobule of parenchyma consisted of exocrine and endocrine portions. Islets of Langerhans were seen as scattered clusters of pale pink stained cells among the dark blue stained acinar cell units of the exocrine portion. The exocrine portion consisted of many secretory acini along with the duct system. Each acinus consisted of varying numbers of single rows of polygonal-shaped acinar cells. The duct system consisted of centroacinar cells, intercalated ducts, intralobular ducts, interlobular ducts and the main pancreatic duct. The pancreatic duct lumen was very large and was lined by columnar epithelium.
