Effects of estrogen deficiency on liver function and uterine development: assessments of activities as estrogenic, anti-lipidemic, and antioxidant agents using an ovariectomized mouse model.

We investigated the effects of supplementation on the lipid profiles and antioxidant capacities of ovariectomized mice.The study was performed on white Swiss female mice that were divided into five groups: control, treated with (0.75 g/kg/day), ovariectomized, ovariectomized treated with β-estradiol (1 μg/day) or with . The mice were sacrificed after 3 and 8 weeks of treatment.Ovariectomy induced a decrease in overall growth, uterine atrophy, and hyperlipidemia demonstrated by increased cholesterol, triglycerides, and decreased HDL. We have shown the involvement of oxidative stress in this hepatic lesion proven by increased levels of TBARS, GPX, and GSH, and decreased levels of SOD and catalase.Treatment with restores lipid balance, the activity of antioxidant enzymes and improves lipid peroxidation. This is probably due to the richness of this plant in polyphenols and flavonoids considered as an antioxidant and phytoestrogenic elements.
