| Abstract |
|
The regional distributions and relative frequencies of the gastrointestinal endocrine cells in the bean goose (Anser fabalis Latham) were investigated by immunohistochemical methods using bovine Sp-1/chromogranin (CG), serotonin, gastrin, cholecystokinin (CCK)-8, somatostatin and glucagon antisera. BCG-immunoreactive cells were widespread throughout the gastrointestinal tract (GIT) with moderated frequencies except for the gizzard and proventriculus which were a few frequencies. Serotonin-immunoreactive cells were detected throughout the GIT except for the proventriculus and gizzard. These cells were observed in the pylorus with rare frequencies but numerous cells were detected in the intestinal tract. Gastrin-immunoreactive cells were restricted to the gizzard, pylorus and duodenum. These cells were most predominant in the pylorus and a few or rare in the gizzard and duodenum, respectively. CCK-8-immunoreactive cells were observed from the gizzard to ileum. The highest frequencies of endocrine cells were observed in the duodenum. These cells were increased from the gizzard to duodenum but thereafter decreased. Somatostatin-immunoreactive cells were detected in the GIT except for the large intestine. In the proventriculus and pylorus, numerous immunoreactive cells were demonstrated but a few cells were present in the other regions. Glucagon cells were observed in the gizzard, pylorus, ileum, colon and rectum with a few or moderated numbers. |
