다국어 초록 (Multilingual Abstract)

The pancreatic endocrine cells of the cat-shark, S. torazame, were studied using immunohistochemical method. Five kinds of endocrine cells (glucagon-, somatostatin-, insulin-, 5-HT-and BPP-immunoreactive cells) identified in this study. The chracteristic findings of the distributions of five immunoreactive cells were as follows. Glucagon-immunoreactive cells were detected as clustering group in the epithelia of the interlobular duct and singly the pancreatic acini, respectively. Insulin -immunoreactive cells were moderately observed in the epithelia of the interlobular duct or in the periphery of the islet. Somatostatin-immunoreactive cells were distributed in single or mass groups in the epithelia of the interlobular duct and the exocrine gland of the pancreas. A very few 5-HTimmunoreactive cells were seen in the periphery of the islet and the acini of the pancreas-BPP-immunoreactive cell was singly located in the periphery of the pancreatic islet, but GAS/CCK-and Chromogranin-immunoreactive cells were not found in this study.
