Cisplatin is an important antineoplastic drug used in multiple chemotherapeutic regimens but unfortunately causes serious toxic effects as ovarian and uterine toxicity. This study aimed to investigate the potential protective effect of resveratrol (RSV) against cisplatin-induced ovarian and uterine toxicity in female rats. Thirty-two female Wistar rats were divided randomly into four groups (n = 8 in each). Control group received oral normal saline for 28 days; RSV group received RSV (10 mg/kg; daily) via oral gavage; CIS group received a single dose of CIS (7 mg/kg; i.p.) on the 21st day; (CIS + RSV) group received both RSV and CIS by the same schedules and doses of RSV and CIS groups, respectively. Results demonstrated a significant decrease in MDA level and a significant increase in both glutathione content and activity of the antioxidant enzymes GPx, SOD, and CAT in the tissues of the ovary and uterus of CIS + RSV group in comparison to that of CIS group (P<0.05), also there are significantly decreased tissue levels of the proinflammatory cytokines and enzymes (NF-κB, IL-1β, IL-6, TNF-α, COX-2, and iNOS), increased estradiol, progesterone, prolactin and decreased FSH serum levels in CIS + RSV group compared to CIS group (P < 0.05). Moreover, there is downregulation of tissues Cleaved Caspase-3, NF-κB and Cox-2 proteins as shown in Western blot analysis, also apoptosis was significantly inhibited, evidenced by downregulation of Bax and upregulation of Bcl-2 proteins, and the ovarian and uterine histological architecture and integrity were maintained in CIS + RSV group compared to CIS group. In conclusion, these findings indicate that RSV has beneficial effects in ameliorating cisplatin-induced oxidative stress, inflammation, and apoptosis in the ovarian and uterine tissues of female rats.
