Preliminary evaluation of gastric endocrine cells in rats with experimental uremia.
Chronic renal failure can be the cause of various disturbances in hormonal and electrolyte metabolism, including calcium and phosphate metabolism. The aim of this study was the evaluation of pyloric endocrine cells in Wistar rats with experimental uremia. Fragments of gastric pylorus were collected 30 days after nephrectomy. Paraffin embedded sections were stained with H+E and by silver impregnation. We also performed immunohistochemical reactions with the use of specific antibodies against calcitonin gene-related peptide (CGRP), synaptophysin (SY), somatostatin (ST), and neuronal specific enolase (NSE). The rats with experimental uremia showed an increase in the number of endocrine cells and in intensity of all the examined reactions.
