Quantitative study of the myenteric plexus of the stomach of rats with streptozotocin-induced diabetes

Abstract

The purpose of the present study was to investigate the morphological and quantitative alterations of the myenteric plexus neurons of the stomach of rats with streptozotocin-induced chronic diabetes and compare them to those of non-diabetic animals. Samples from the body of the stomach were used for whole-mount preparations stained with NADH-diaphorase and for histological sections stained with hematoxylineosin. It was observed that diabetes cause a significant decrease on the number of neurons.
