Abstract


Recently, the researches on the enteroendocrine cells of vertebrates have made a remarkable advance by the immunocytochemical methods. This study was attempted to investigate the topographical distributions and the shapes of gastrin, glucagon, somatostatin and cholecystokinin-8 immuno-reactive cells in the gastrointestinal tract of the Korean hedgehog, Erinaceus koreanus. For light-microscopical examination of immunocytochemistry, the tissue specimens taken from the various portions(body and pyloric protion of stomach, duodenum, jejunum, ileum and rectum) were fixed in glutaraldehyde-picric acid-acetic acid (GPA) or 10% neutral buffered formalin solutions. For the demonstration of immunoreactive cells, the paraffin sections (μm) were immunocytochemically identified by PAP procedure (Sternberger, 1979) with gastrin, glucagon, somatostatin and cholecystokinin-8 antisera. Gastrin-immunoreactive cells were mainly distributed in the pyloric portion of stomach and were a few in the duodenum and jejunum. The shapes of these cells were round or oval in the pyloric portion and pyramidal in the small intestine. Glucagon-immunoreactive cells were sparsely distributed in the only small intestine. The shapes of these cells were mainly pyramidal. Somatostatin-immunoreactive cells were a few in the pyloric portion and duodenum, and were sparsely distributed in the body of stomach and jejunum. The shapes of these cells were round or oval in the stomach and oval or pyramidal in the small intestine. Cholecystokinin-8-immunoreactive cells were sparsely distributed in the only small intestine. The shapes of these cells were mainly oval or pyramidal.
