Protective effects of resveratrol on testicular oxidative stress induced of MK-801 in mice

Abstract

Recently, it has been discovered that the doses of the MK-801 causing schizophrenia also initiate the oxidative stress in the testis. The current study investigated the protective role of the resveratrol against the MK-801 induced oxidative stress in the testis in mice. The testis weight, the total oxidant-antioxidant status, seminiferous tubules diameter, epithelial height, testicular pathology, and epididymal sperm motility were evaluated. A total of 24 male mice were equally divided into 4 groups so that each group included 6 mice. In the study, Group I (control group) was intraperitoneally received with 0.9% saline (10ml/kg). Group II was i.p. administered with MK-801 (1mg/kg), Group III was treated with i.p. MK-801 (1mg/kg) and resveratrol (40mg/kg), and the Group IV was treated i.p. with resveratrol (40mg/kg). All injections were performed for 14 days. According to the results, in the testis of mice in Group II the oxidative stress was observed. The oxidative stress affected the seminiferous tubules pathologically and decreased the weight of the testis and sperm motility. However, resveratrol protected the MK-801 induced oxidative stress in the testis. Moreover, this dose of the resveratrol increased the sperm motility compared with the controls. In conclusion, MK-801 caused oxidative stress in the testis and resveratrol had a protective effect against this damage.
