Abstract:

Cadmium (Cd) is one of the environmental pollutants affecting various tissues and organs including testis. The aim of this study was to investigate the anti-apoptotic effects of curcumin (Cur) on Cd-induced apoptosis in rat testes. The rats were randomly allotted into one of three experimental groups: control, Cd treated and Cd treated with Cur; each group contained 10 animals. The control group received 2 ml/day of dimethyl sulfoxide (DMSO). To induce toxicity, Cd (1 mg/kg body weight) was dissolved in normal saline and subcutaneously injected into rats for 4 weeks. The rats in Cur-treated group was given a daily dose of 100 mg/kg of Cur for 4 weeks. To date, no examinations of the anti-apoptotic properties of Cur on Cd-induced apoptosis in rat testes have been reported. The mean seminiferous tubule diameter, mean testicular biopsy score values and serum testosterone levels were significantly decreased in Cd-treated groups were compared to the control group. Furthermore, the Cur-treated animals showed an improved histological appearance and serum testosterone levels in Cd-treated group. Our data indicate a significant reduction in the activity of in situ identification of apoptosis using terminal dUTP nick end-labeling in testis tissues of the Cd-treated group with Cur therapy. The present study showed that Cur treatment protected testes against toxic effects of Cd. We believe that further preclinical research into the utility of Cur may indicate its usefulness as a potential treatment on the spermatogenesis after testicular injury caused by Cd-treated rats.
