The localization of substance P(SP), calcitonin gene-related peptide(CGRP) and three calcium binding proteins, calbindin D-28k(CB), calretinin(CR) and parvalbumin(PA) was immunohistochemically examined in the myenteric and submucous plexuses of Korean native goat duodenum. In the neurons of myenteric and submucous plexuses of duodenum, immunoreactivities of SP, CGRP and CB were confirmed in both nerve cell bodies and fibers. In contrast, CR immunoreactivity was found only in nerve fibers of myenteric plexuses, while PA immunoreactivity was found only in nerve cell bodies of submucoun plexuses. In the inner circular muscle layer, dense SP-like immunoreactive fibers were prominent but only a few CGRP-like immunoreactivities were observed. Most of SP-and CGRP-like immunoreactive neurons of both plexuses colocalized with CB. This result showed that SP and CGRP may have a important role for the movement of small intestine. The colocalizations of CB with SP or CGRP in myenteric and submucous plexuses suggest that CB may serve neuromodulatory role for SP-and CGRP-immunoreactecd neurons on the movement of intestinal wall.
