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 polypetide (GIP), neurotensin, secretin, gastrin and substance P. In the abomasum, chromograin-, serotonin-, somatostatin-, motilin-, glucagon-, gastrin-, and substance P-immunoreactive cells were found. Chromogranin- and serotonin- and serotonin-immunoreactive cells were more numerous in the fundic region than pyloric region. Somatostatin- and gastrin- immunoreactive cells were numerous in the pyloric region than in the fundic region. 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
