ABSTRACT
The colocalization of three putative inhibitory mediators of enteric nerves, vasoactive intestinal peptide (VIP), galanin (GAL) and nitric oxide synthase (nNOS), was examined in the myenteric plexus of canine antrum, intestine and colon. Many ileal and colonic neurons contained nNOS-immunoreactive (nNOS-IR) activity with some also containing VIP-IR; only a few neurons also contained GAL-IR. Ileal and colonic VIP-IR nerves often appeared to be interneurons innervating nNOS nerves. Many antral neurons contained VIP-IR with nearly all also containing GAL-IR. A few also contained nNOS-IR. The predominance of nNOS-IR neurons relative to VIP-IR and GAL-IR neurons in the ileal and colonic, but not the antral, myenteric plexus is consistent with NO being the primary inhibitory mediator in the intestine but not in the antrum.
