Endocrine cells in the gastrointestinal tract mucosa of zander (Stizostedion lucioperca) [Sudak (Stizostedion lucioperca) gastrointestinal kanal mukozasi{dotless}ndaki endokrin hücreler]

The distribution and relative frequency of endocrine cells in the gastrointestinal tract of the zander (stizostedion lucioperca) were studied immunohistochemically using the peroxidase anti-peroxidase complex method. our aim was to determine the distribution of specific immunoreactivities in some regions of digestive tract of the zander against the antisera calcitonin gene related peptide (cgrp),bombesin,somatostatin-14,secretin,trk-a,trk-b,trk-c,histamine,neurotensin,neuropeptide y (npy). the samples were taken from the stomach,intestine and pyloric caeca. data were subjected to analysis of variance spss 10 statistical software programme and analysis of variance results were significant in the region of average density immunreactive cell type were compared with anova test. the immunoreactivities against all antisera were observed as intensively in the cells of the gland and less in the cells of lamina epithelialis. the most intensive region of immunoreactive cells were determined as the fungus. immunoreactivity was not observed in the nerves beloging to the myenteric plexus and muscle tissue and also ganglion cells.
