Jian-Pi-Yi-Shen decoction inhibits mitochondria-dependent granulosa cell apoptosis in a rat model of POF


Figure 2. JPYS improved the abnormal estrous cycle and rate of pregnancy in premature ovarian failure (POF) rats. Rats were treated with JPYS (11.0 g/kg.d) and pre-treated with triptorelin (1.5 mg/kg) followed by intraperitoneally injected cyclophosphamide (50 mg/kg). (A) Estrous cycle of the rats (Estrous interval period: Vagina smear with white blood cells mainly; Preestrus period: With nuclear epithelial cells mainly; Estrous period: With Keratinized epithelial cells mainly; Late estrous period: See Keratinized epithelial cells and white blood cells) (n=6); (B) The rate of pregnancy (Female rats of each groups were sent to mate with male rats with ratio of 1:1 for 12 h. The mixture of sperm and vaginal smears seen on the next morning indicated the success of pregnancy, and this was considered as the 0.5 th day of the gestation. The pregnant rats were euthanized on the 13.5 th day of the gestation) (n=4); (C) The rate of abnormal estrous cycle (n=6). Data are shown as mean ± SD. *p < 0.05 versus control group, #p < 0.05 versus POF group, p < 0.05 versus JPYS group.
