A Study of the Early Changes of the Level of Calcitonin Gene-Related Peptide and Histopathology of Penises of Rats with Experimentally Induced Type I Diabetes Mellitus by Streptozocin

INTRODUCTION: Diabetes mellitus (DM) is a multiorgan disease that leads to neurovascular complications that disturb the normal erectile function. AIM: The aim of the current work was to study the early changes occurring in the level of calcitonin gene-related peptide (CGRP) and histopathological cha...

description INTRODUCTION: Diabetes mellitus (DM) is a multiorgan disease that leads to neurovascular complications that disturb the normal erectile function. AIM: The aim of the current work was to study the early changes occurring in the level of calcitonin gene-related peptide (CGRP) and histopathological changes in penile tissues of uncontrolled diabetic rats. MATERIALS AND METHODS: This study was carried on 50 adult male Sprague-Dawley rats divided into two main groups: group I (control, n = 10) and group II (diabetic, n = 40). Type I DM was induced by a single intraperitoneal injection of streptozotocin (60 mg/kg). The tissue level of CGRP and histopathological examination of rat penises were assessed at 2, 4, 6, and 8 weeks after induction of DM. RESULTS: CGRP was higher in the diabetic group at 4, 6, and 8 weeks than in the control group. However, endothelial changes and decreased smooth muscles mass started only 2 weeks after induction of DM. CONCLUSION: Deterioration of histopathological features of the uncontrolled diabetic rats corporeal tissues is time dependent. Furthermore, vascular changes seem to precede the neurological changes.
