RESUMO
Background: Bisphenol A [BPA] is an environmental chemical that has been widely used in the manufacture of polycarbonate plastics and epoxy resins for many years. Due to its major applications in the production of plastic food or beverage containers and the coating of food cans, people of different ages are inevitably exposed to BPA in daily life. It is a contaminant with increasing exposure to it and exerts both toxic and estrogenic effects on mammalian cells
Aim of the work: the present study was designated to evaluate the histopathological and immunohistochemical effect of BPA on the histoarchitecture of pituitary ,adrenal, ovarian and uterine axis of female albino rats and the ameliorative effect of antiestrogen drug and stem enhance
Experimental model and methods: 20 female albino rats weighing 100 - 120 g. were kept under observation for about 15 days before the onset of the experiment for adaptation, then the rats were classified into 4 groups 5 rats for each , the first group was left without any treatment for 30 days as negative control group , the second group was administered with 20 mg/kg.bw of BPA for 15 consecutive days as positive control, the third group administered with 20 mg/kg.bw of BPA for 15 consecutive days and then treated with antiestrogen drug as 0.1 mg/100gm.bw for 15 day, the fourth group administered with the same dose for the same period and the treated with stem enhance [4.5 mg/100.bw] for 15 days. All rats are scarified and organs were histologically examined after processing
Results: The results showed that PA has a histopathological effects on vital organs [pituitary, adrenal, ovary, oviduct and uterus] even for a short period with minimal ameliorative effect of antiestrogen drug and stem enhance
