Abstract
The present study investigated the protective efficacy of dl-α-lipoic acid (LA) on adriamycin (ADR)-induced oxidative damage in rat testis. Adult male albino rats of Wistar strain were administered ADR (1 mg/kg body weight, i.v.), once a week for 10 weeks. ADR injected rats showed increased oxidative stress with a concomitant decrease in cellular thiols. The mRNA level for phospholipid hydroperoxide glutathione peroxidase (PHGPx) was also significantly decreased by ADR administration. Transmission electron microscopic (TEM) observations of testicular germ cells revealed abnormal ultrastructural changes in ADR treated rats. Treatment with lipoic acid (35 mg/kg body weight, i.p.) 1 day prior to ADR administration, effectively reverted these abnormal changes towards normalcy. These findings indicate a cytoprotective role of LA in this experimental model of testicular toxicity.
