Effect of mangosteen peel extract on BPA-exposed murine during gestation

Abstract

Aim: To evaluate the potential protective effects of mangosteen peel extract against BPA-induced abnormalities on-pregnant mice fetus at implantation stage and offspring at post-parturition. Methodology: Pregnant mice were orally administered with BPA (100mg kg-1 b.wt.) and mangosteen peel extract (200mg kg-1 b.wt.) for 16 days. In order to evaluate the effect of MPE treatment on fetus at implantation stage, the pregnant mice were euthanized at day 18 and the fetus number and morphology were examined. Another group of treated dams, were allowed to undergo parturition for evaluating the of maternal weight, litter size and offspring sex-skewness. Results: Upon feeding Mangosteen peel extract (MPE), the average daily weight gain of dams were not significantly different from the control and BPA treated dams. The fetus derived from BPA treated dams were detected with abnormalities such as under development, haemorrhage and absence of vein, whereas fetus from dam treated with MPE and BPA as well as control were normal. The average litter size of all the treatment groups were not significantly different from the control group. BPA treated mice had lower pups survival up to 6 weeks compared to the groups treated with MPE and control. Test of proportion analysis showed BPA-treated group had significantly higher fraction female ratio. Interpretation:BPA is known as endocrine disruptor causing oxidative stress to female reproductive system, hence mangosteen peel extract contains antioxidant substances that have the potential to ameliorate the adverse effects of BPA exposure on dams during pregnancy and its fetus development.
