Immunohistochemical study of the endocrine cells in the stomach and pyloric caeca of the mountain trout, Salmo trutta macrostigma

Authors

Abstract

 The endocrine cells of Salmo trutta macrostigma stomach and
pyloric caeca have been investigated using immunohistochemical techniques. 8
antisera were tested and 6 of them were detected in the endocrine cells serotonin,
somatostatin, substance P, galanin, CCK and neuropeptide Y. These
immunoreactive cells are described for the first time in the stomach and
pyloric caeaca of Salmo trutta
macrostigma. Neurotensin and VIP immunoreactivity were not detected in
these regions. The regional distribution and relative frequency of the endocrine
cells in the stomach and pyloric caeca of Salmo
trutta macrostigma were resembled (with respect to serotonin, somatostatin,
CCK and substance P immunoreactivity) and showed also some particularities
(presence of galanin and NPY positive cells) to those of the other salmonid
species.
