RESUMEN
Objective:To investigate the effect of Ding Kundan on the expression of TGF-β1,CTGF and AR in PCOS model rats,and to explore its treat mechanism on PCOS.Methods: The PCOS model rats induced by DHEA were intervened with high, medium and low dose of Ding Kundan(4.5,2.25,1.125 g/kg),ELISA,immunohistochemistry,RT-PCR and Western blot were used to detect serum hormone levels,mRNA and protein expression of TGF-β1,CTGF and AR in each group of rats.Results: Compared with model group Ding Kundan high,medium and low dose group of E2,LH and T were decreased,while FSH was increased.And the differences were statistically significant.Protein expression and mRNA of TGF-β1,CTGF and AR were decreased,and the differences were statistically significant.Conclusion: Ding Kundan shows significantly therapeutic efficacy on PCOS rats,and its possible mechanism is related to regulating expression levels of TGF-β1,CTGF and AR in ovarian tissue.
