| Abstract | ||
| Testicular damage is one of the most deleterious effects whenever cisplatin (CIS) is employed in cancer chemotherapy. Oxidative stress has been proven to be involved in CIS induced toxicity. Thus, the current study explored the possible protective effect of L-carnitine (L-CAR) against cisplatin-induced testicular damage in rats. L-carnitine (500 mg/kg/day; i.p.) was injected for 15 days, whereas cisplatin (10 mg/kg; i.p.) was injected as a single dose at the 12th day to induce testicular damage in adult male Sprague-Dawley rats. In the current study, CIS reduced the reproductive organs weight, sperm count, sperm motility and serum testosterone level beside a marked increase in the incidence of sperm abnormalities. In addition, it significantly increased malondialdehyde (MDA) and nitric oxide (NO) along with a marked decrease in testis reduced glutathione (GSH) content and superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GPx) activities. At the same time, CIS administration resulted in marked elevation in tumor necrosis factor-α (TNF-α) production and nuclear factor-kabba B (NF-κB) expression. These results were confirmed by histopathological examination. Treatment with L-CAR markedly attenuated cisplatin-induced injury by suppression of oxidative/nitrosative stress and inflammation, amendment of antioxidant defenses, as well as improvement of steroidogenesis, spermatogenesis and testicular histological features. This study suggests a novel therapeutic application for L-carnitine as a protective agent against cisplatin-induced testicular toxicity through its promising anti-inflammatory and antioxidant capacities. | ||
