The Intervention Effect of Rosiglitozone in Ovarian Fibrosis of PCOS Rats

Abstract Objective To explore the Intervention effect of Rosiglitozone in ovarian fibrosis of PCOS rats. Methods 60 female SD rats were randomly divided into 3 groups: control group, model group and treatment group. The model and treatment groups were established by subcutaneous injection of DHEA, while the treatment group was given RGZ. The serum hormone values, pathohistology of ovarian structure of rats, ovarian ultrastructure and the expressions of TGF-β 1 and CTGF were detected. Results The PCOS model was established successfully. The expression intensity of TGF-β 1 and CTGF in Oocytes of the PCOS groups was 9.545±2.954 and 9.665±2.400, respectively and was significantly higher than that of the control group 6.636±2.264 and 7.036±2.133; after treatment with rosiglitazone, the expression was significantly decreased 6.980±2.421 and 6.642±2.721 as compared with that of the model group ( P P P P P P Conclusion TGF-β 1 and CTGF play an important role in the development of ovary fibrosis in PCOS. However, RGZ may postpone the development of fibrosis by decreasing the levels of TGF-β 1 and CTGF.
