The purpose of this study was to examine the effects of electroacupuncture at Zusanli on the immunohistochemical density of enteroendocrine cells related to gastrointestinal function. The authors investigated the histochemical changes of mucous substances and immunohistochemical density of gastrin, serotonin, calcitonin gene-related peptide (CGRP), insulin, and pancreatic polypeptide (PP) secreting cells in rats. Staining density of mucous substances and the enteroendocrine cells of the gastrointestinal tract was observed with histochemical and immunohistochemical methods. Stainless steel needles with a diameter of 0.25 mm were inserted into Zusanli (St36, 5 mm below the head of the fibula under the knee joint, and 2 mm lateral to the anterior tubercle of the tibia) and connected to an electrical stimulator. The electroacupuncture (EA) stimulation was delivered for 30 minutes at 10 mA, 2 Hz in EA stimulation (2EA group) or 4 Hz in EA stimulation (4EA group) in each experimental group. In 4EA stimulation at the Zusanli, staining density of Alcian blue-periodic acid-Schiff on mucous substances of the stomach body was stronger than those of the 2EA and control groups. Periodic acidi-Schiff staining

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.
