a 4-year-old female miniature pincher with a 40-day history of weight loss, lethargy and vomiting was referred to small animal hospital, faculty of veterinary medicine, university of tehran. the case also had severe jaundice, chronic diarrhoea and steatorrhoea. the efforts for saving the life of the case were not successful and finally the animal died of hypovolaemic shock and electrolyte imbal...

Histological and histochemical studies on the pancreas of goose (Anser albifrons) were carried out using special staining and light microscope. The pancreas in goose is serous tubuloacinar gland having exocrine and endocrine part. Smooth muscle fibres were absent in capsule of pancreas. Acinar cells have bizonal shape. Intralobular ducts, Interlobular and main excretory ducts were present withi...

regarding to the important of pancreas in the body, this study was carried out on the histologic structure of pancreas of 6 pairs of iranian native turkeys of both sexes, age ranging from 26-30 weeks. routine histological techniques were used and stained by h&e; and masson’s trichrome, gomori’s method for reticulum, verhoeff’s, maldonado’s methods. the pancreas was covered with a thick dense co...

the histological analysis, disposition and histochemical localization of tryptophan were investigated in the pancreas to compare the cellular organization and histochemical characterization in the pancreas of labeo rohita (hamilton, 1822), mystus vittatus (bloch, 1790) and notopterus notopterus (pallas, 1769) having different feeding habits. histological analysis demonstrated that the exocrine ...

The homeodomain protein PDX-1 is critical for pancreas development and is a key regulator of insulin gene expression. PDX-1 nullizygosity and haploinsufficiency in mice and humans results in pancreatic agenesis and diabetes, respectively. At embryonic day (e) 10.5, PDX-1 is expressed in all pluripotential gut-derived epithelial cells destined to differentiate into the exocrine and endocrine pan...

The pancreas plays a critical role in the control of nutritional homeostasis. It consists of two major parts, the exocrine pancreas, which releases digestive enzymes; and the endocrine pancreas, which releases hormones such as insulin, glucagon, pancreatic polypeptide and somatostatin and maintains glucose homeostasis. Cells in the endocrine pancreas are organized in pancreatic clusters of cell...

histomorphologic and histomorphometric studies on the pancreas of mehraban male sheep were done in four age groups: fetus, neonate, young adult and old age in this respect, we used special stainings, light microscope and ocular micrometer. the results showed that the smooth muscles were absent in capsule. the tubular portion of exocrine pancreas was more prominent. neuroinsular complex and beta...
