Abstract (original English)

Introduction The interaction between advanced glycation end-products (AGEs) and its receptors for AGEs (RAGEs) elicits oxidative stress and mediates the development of erectile dysfunction (ED). ALT-711, an AGE cross-link breaker, has the therapeutic potential for ED but has been less intensively investigated. Aim The aim of this study was to investigate the effects of an AGEs breaker 3-phenacyl-4, 5-dimethylthiazolium chloride (ALT-711) plus insulin on erectile function in streptozocin (STZ)-induced type 1 diabetic rats. Methods: Fifty 8-week-old Sprague-Dawley rats were randomly distributed into five groups: normal control (C), diabetic (D), insulin-treated diabetic (D + I), ALT-711-treated diabetic (D + ALT-711) and insulin plus ALT-711- treated diabetic (D + I + ALT-711) rats. Diabetes was induced by a single intraperitoneal injection of STZ. Eight weeks after induction of diabetes, ALT-711 was administered by intraperitoneal injection. Two to six units of intermediate-acting insulin were utilized to achieve normal levels of glycemic control. After treatment for 6 weeks, erectile function was determined via measurement of intracavernous pressures (ICPs) following electrostimulation of the cavernous nerve. The deposition of AGEs, expression of RAGEs, superoxide dismutase activity, and lipid peroxidation were measured. We also evaluated penile histological changes such as smo
