Abstract |
Regional distribution and relative frequency of endocrine cells in ten portions of the gastrointestinal tract of the Korean native cattle were observed by immunocytochemical methods using specific antisera against chromogranin, serotonin, somatostatin, glucagon, bovine pancreatic polypeptide(BPP), motilin, gastric inhibitory polypeptide(GIP), neurotensin, secretin, gastrin and substance P. The results observed are summarized as follows: In the abomasum, chromogranin-, serotonin-, somatostatin-, motilin-, glucagon-, gastrin-, and substance P-immunoreactive cells were found. Chromogranin-and serotonin-immunoreactive cells were more numerous in the fundic region than pyloric region. Somatostatin- and gastrinimmunoreactive cells were numerous in the pyloric region than in the fundic region. In the small intestine, chromogranin-, serotonin-, somatostatin-, glucagon-, BPP-, motilin-, gastrin-, GIP-, neurotensin-, secretin-, and substance P-immunoreactive cells were detected. Chromogranin-, somatostatin-, GIP- and secretin-immunoreactive cells were most numerous in the duodenum, while BPP-, motilin-, glucagon-, neurotensin- and substance P-immunoreactive cells were rarely seen in the small intestine. In the large intestine, chromogranin-, serotonin- and BPP-immunoreactive cells were widely distributed and most numerous in the rectum. Somatostatin-, glucagon- and substance P-immunoreactive cells were rarely seen in the large intestine. |
