RESUMEN
Objective To observe efficacy of Zishen Ankun Granules in treatment of mice with immune premature ovarian insufficiency(POI)and its influence on cytokines interleukin 2(IL2),interleukin 6(IL6)and transforming growth factor-β(TGF-β)Methods Screening female mice with regular estrus to establish immune POI mice model with zona pellucida 3(ZP3)as antigen.Low and high doses of Zishen Ankun Granules were set up for treatment,and estradiol valerate was used as a positive control.Observing the estrous cycle of mice by papanicolaou staining,observing the morphological changes of ovarian tissues by HE staining,and detecting serum estradiol(E2),follicle-stimulating hormone(FSH),anti mullerian hormone(AMH),IL2,IL6 and TGF-β levels by ELISA.Results Compared with the blank control group,the estrous cycle of model group was prolonged and disordered,inflammatory cell were infiltrated in the ovarian stroma,growth follicles were decreased,and atresia follicles were increased(P<0.05,P<0.01);serum E2,AMH and TGF-βlevels were decreased(P<0.01),serum FSH,IL2 and IL6 levels were increased(P<0.01).Compared with model group,the estrous cycle disorder and inflammatory cell infiltration were improved in each treatment group,in which the growing follicles increased in the high dose group of Zishen Ankun and the atretic follicles decreased in the estradiol valerate group(P<0.05);serum E2,AMH and TGF-βlevels were increased in Zishen Ankun high dose group and estradiol valerate group(P<0.05,P<0.01),Serum FSH and IL6 levels in Zishen Ankun high-dose group were decreased(P<0.05),Serum IL2 levels was decreased in each treatment group(P<0.05,P<0.01).Conclusion Zishen Ankun granules can improve the levels of serum reproductive hormone,IL2,IL6 and TGF-βin immune POI mice,reduce the inflammatory response of ovary,regulate immune disorders,improve the ovarian reserve capacity,and play a protective role on the ovary.
