OBJECTIVE: The therapeutic value of cisplatin (CDDP) as an anticancer drug is limited by its ovo-otoxicity. The effect of natural phenolic acids in the prevention of many diseases related to oxidative stress has been reported. Here, the ability of p-coumaric (pCA) acid, a member of phenolic acids, to protect rat ovary tissue against CDDP-induced oxidative stress was investigated. METHODS: The study was carried out in five main groups containing six rats in each group: control, pCA (4 mg/kg), CDDP, CDDP plus pCA (2 mg/kg), and CDDP plus pCA (4 mg/kg). The levels of ovarian malondialdehyde (MDA), total oxidant status (TOS), total antioxidant status (TAS), oxidative stress index (OSI), catalase (CAT), 8-hydroxy-2'-deoxyguanosine (8-OHdG), caspase-3, and tumor necrosis factor-alpha (TNF-α) were determined. Hematoxylin and eosin staining method was employed for the histopathological examination. RESULTS: In the CDDP group, it is determined that statistically significant decreasing in the levels of TAS and CAT, and increasing in the levels of MDA, TOS, OSI, 8-OHdG, caspase-3, and TNF-α compared with control group (p < 0.05). pCA administration statistically significantly restored this damage in a dose-dependent manner (p < 0.05). Although vascular congestion, edema, hemorrhage, follicular degeneration, and leukocyte infiltration were significantly higher in the CDDP group than in the control group, pCA administrations statistically significantly restored these damages (p < 0.05). CONCLUSIONS: The data presented here indicate that pCA protects ovarian tissues of rats against CDDP-induced oxidative stress, inflammation, and apoptosis. It may be worthy to consider the usefulness of pCA as adjuvant therapy in cancer management.
