Abstract

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 connective tissue which consisted of elastic, reticular and collagenous fibers and was lined by Mesothelium. Lobulation is indistinct because of the lack of interlobular connective tissue. Reticular fibers were present into pancreatic islets. Parasympathetic ganglia were observed in interlobular connective tissue. The parenchyma consisted of exocrine and endocrine parts. The exocrine part was composed of tubuloacinar gland. Goblet cells and glands were not present in duct system. The endocrine part was composed of large alpha and small beta islets but mixed islets were not observed.
