Mechanism of Xiao Chaihu Decoction in the Treatment of Endometriosis

Objective To explore the mechanism of Xiao Chaihu decoction in t he treatment of endometriosis in rats.Methods The rat model of endometriosis w as established. Fas and Caspase- 3 protein expression in the eutopic endometriu m and eutopic endometrium were observed by immunohistochemical method.Results The protein expression of Fas and Caspase- 3 in ectopic endometrium of Xiao Cha ihu decoction group was higher than that in the eutopic endometrium, while the r esult in the control group was just the opposite. No significant difference was shown in Danazol group. Conclusion The therapeutic mechanism of Xiao Chaihu de coction for endometriosis may be related to the promotion the apoptosis of ectop ic endometrium tissue by increasing Fas protein expression.
