Comparison of effects of curcumin and beta-carotene on ovarian damage caused by cisplatin

Abstract

Purpose: We aimed the potential protective effects of curcumin (CUR) and beta-carotene (BC) against cisplatin (CIS)-induced ovarian damage using histological and immunohistochemical methods.
 Materials and Methods: We used 56 female Wistar albino rats, divided randomly into seven groups. Control rats did not receive any treatment; the sham group was administered 1 ml/kg sesame oil by gavage; the CIS group 5 mg/kg CIS; the CUR group 200 mg/kg CUR; the BC group 100 mg/kg BC; the CUR + CIS group, CIS after administration of CUR; the BC + CIS group was pretreated with BC, then administered CIS. The ovaries of all groups were excised five days after the last application. We assessed histopathology and counted and classified follicles. Expression of anti-Mullerian hormone (AMH) and nuclear factor-kappa B (NF-κB) was detected immunohistochemically. Apoptosis was evaluated using the TUNEL method.
 Results: CUR and BC are protective against decreased numbers of primordial, primary, preantral, secondary, and tertiary follicles caused by CIS. Both Cur and BC reduced ovarian NF-κB levels in comparison to the control group, and AMH immunoreactivity was almost identical for the control and CUR + CIS groups. Apoptotic cell counts indicated that CUR exerts a stronger anti-apoptotic effect than BC.
 Conclusion: CUR has a protective effect against ovarian damage brought on by CIS and greater antioxidant and anti-inflammatory properties than BC.
