چکیده انگلیسی
Adriamycin (ADR), an anthracycline antibiotic, which is widely used as an antineoplastic drug in the treatment of various solid tumors, has been shown to induce reproductive abnormalities in males. In the present study, the effect of lipoic acid (LA), a universal antioxidant was investigated on ADR-induced testicular toxicity in rats. Adult male albino rats of Wistar strain were administered ADR (1Â mg/kg body weight, i.v.), once a week for 10 weeks. Mitochondrial fractions of the testis were obtained by differential centrifugation. The activities of mitochondrial antioxidant enzymes such as superoxide dismutase, glutathione peroxidase and glutathione reductase were decreased significantly in the animals treated with ADR. The levels of mitochondrial lipid peroxides and hydrogen peroxide were increased in ADR-treated rats. ADR-treated rats also showed decline in the activities of mitochondrial enzymes such as succinate dehydrogenase (SDH), malate dehydrogenase (MDH) and isocitrate dehydrogenase (ICDH). Treatment with lipoic acid (35Â mg/kg body weight, i.p.) 1 day prior to ADR administration, maintained near normal activities of the enzymes, thereby proving to be an effective cytoprotectant.
