Abstract

The gut of silver eels (Anguilla anguilla L.) was investigated in order todescribe both the cholinergic and adrenergic intramural innervations, and the localization of possible accessory neuromediators. Histochemical reactions for the demonstration of nicotinamide adenine dinucleotide phosphate, reduced form(NADPH-)diaphorase and acetylcholinesterase (AChEase) were performed, as well as the immunohistochemical testing of tyrosine hydroxylase, met-enkephalin, substance P, calcitonin gene-related peptide (CGRP), bombesin, vasoactive intestinal peptide (VIP), neuropeptide Y (NPY), somatostatin,cholecystokinin-octapeptide (CCK-8), serotonin, cholineacetyl transferase. The results evidenced a different pattern in comparison with other vertebrates, namely mammals, and with other fish. Both NADPH-diaphorase and AChEase activities were histochemically detected all along the gut in the myenteric plexus, the inner musculature and the propria-submucosa. Tyrosine hydroxylase immunoreactivity was observed in the intestinal tract only, both in the myenteric plexus and in the inner musculature. Several neuropeptides (metenkephalin, CGRP, bombesin, substance P, VIP, NPY, somatostatin) were, in addition, detected in the intramural innervation; some of them also in epithelial cells of the diffuse endocrine system (met-enkephalin, substance P, NPY, somatostatin). Serotonin was only present in endocrine cells. Tyrosinehydroxylase immunoreactivity was present in localizations similar to thoseof NADPH-diaphorase-reactivity, and in the same nerve bundles in which substance P- and CGRP-like-immunoreactivities were detectable in the intestinal tract. In addition, NADPH-diaphorase-re active neurons showed an anatomical relationship with AChEase-reactive nerve terminals, and a similar relationship existed between the latter and substance P-like immunoreactivity.
