Effect of Yushen zhuyun decoction on rats with diminished ovarian reserve induced by tripterygium glycosides

摘要

Purpose: To investigate the effect of Yushen zhuyun decoction (YSZYF) on rats with diminished ovarian reserve (DOR). Methods: High-performance liquid chromatography (HPLC) was used to determine the major phytochemical constituents of YSZYF. Rats with DOR (DOR rats) were prepared by administration of tripterygium glycosides (TWP) orally (50 mg/kg) for 15 days. Thereafter, DOR rats were treated orally with YSZYF (300, 600 and 900 mg/kg). After 15 days’ treatment, ovary index was calculated and blood was obtained to determine serum levels of follicle-stimulating hormone (FSH), estradiol (E2), progesterone (P), testosterone (T), inhibin (INH) and anti-mullerian hormone (AMH) by radioimmunoassay and enzyme-linked immunosorbent assay (ELISA). In addition, the ovary was subjected to histopathological examinations. Results: Phytochemical investigation indicated that the major constituents of YSZYF are acteoside, loganin, lcariin and echinacoside. Compared to the control rats, YSZYF treatment enhanced the ovary index of DOR rat (p 0.05); furthermore, YSZYF treatment also enhanced the number of follicles and corpus luteum, as well as alleviated inflammatory reaction in ovary tissues. Additionally, the serum levels of FSH and T were elevated by treatment of YSZYF (p 0.01), whereas E2, INHB and AMH concentrations decreased (p 0.01), compared to control rats. Conclusion: The findings indicate that YSZYF improves ovarian reserve of DOR rats, and thus has a potential for treating infertility.
