| Abstract |
|
The regional distribution and relative frequencies of the gastro-entero-pancreatic endocrine cells were studied immunohistochemically in the GIT and pancreas of the Korean mole. Seven kinds of endocrine cells were identified in this study. Although 5-HT- and somatostatin-immunoreactive cells were seen throughout the GIT, they were most predominant in the pyloric gland region. Glucagon-immunoreactive cells were restricted on the large intestine. Bovine CG-immunoreactive cells were more frequent in the stomach than in the intestines which were not detected in the duodenum. Numerous Gas/CCK-immunoreactive cells were found in the pyloric gland region, but rarely in the jejunum and ileum. BPP-immunoreactive cells were observed to be rare in the stomach and ileum but were a few in number in the intestines. In the pancreas, four types, namely, glucagon-, somatostatin-, BPP- and insulin-immunoreactive cells were identified in the pancreatic islets and exocrine portion. These results suggest that although endocrine cells of the Korean mole is less abundant in the duodenum, the distribution pattern of its gastro-entero-pancreatic endocrine cells is similar to that reported for the Korean hedgehog. |
