Abstract
The gastrointestinal endocrine cells of the Korean native goat were studied immunohistochemically, and 5-HT-, somatostatin-, Gas/CCK-, glucagon-, chromogranin- and PP- immunoreactive cells were revealed. The characteristic findings of the regional distribution and relative frequency of these immunoreactive cells in the gastrointestinal tract of the Korean native goat were as follows. 5-HT-immunoreactive cells were more numerous in the small and large intestine than in the abdomen stomach. Somatostatin-immunoreactive cell were more numerous in the abdomen stomach than in the small and large intestine. Gas/CCK-immunoreactive cells were concentrated very numerously in the pyloric region with a few in the other regions. Moderate numbers of glucagon-immunoreactive cells were found in the small and large intestine, but a few of them were found in the abdomen stomach. Very numerous chromogranin-immunoreactive cells were detected throughout the gastrointestinal tract. PP-immunoreactive cells were observed moderate numbers in the large intestine with few in the ileum. No insulin-immunoreactive cell was found in the gastrointestinal tract.
