OBJECTIVETo observe the effect of Jingui Shenqi Pill (JSP) and its disassembled recipes (supplementing Shen yang, supplementing Shen yin, and supplementing Shen yang and Shen yin) on ovarian functions of female rats of Shen yang deficiency syndrome (SYDS).METHODSTotally 55 SD female rats were randomly divided into 5 groups, i.e., the normal control group, the model group, the Shen yang supplementing group, the Shen yin supplementing group, the Shen yang and Shen yin supplementing group, 11 in each group. Except the normal control group, rats in the rest group were injected with hydrocortisone at the daily dose of 25 mg/kg at the muscle of femoribus internus for 12 successive days. From the 13th day after successful modeling, rats were administered by gastrogavage with different recipes at the dose of 1 mL/100 g (2.75 g/kg Shen yang supplementing recipe; 6.25 g/kg Shen yin supplementing recipe; 6.75 g/kg JSP), once daily for 20 successive days. Equal volume of normal saline was given to those in the normal control group and the model group, once daily for 20 successive days. Blood was withdrawn from the orbit on the 2nd day after intervention. The serum estradiol (E2) and progesterone (P) were detected using ELISA. The weight of uterus and ovarian index (VI) were calculated. The pathological changes were observed by HE staining.RESULTSThe general condition of rats in the Shen yang and Shen yin supplementing group were improved. The body weight (g) was added by 35.0 +/- 12.5 in the normal control group, 16.7 +/- 7.4 in the model group, 20.2 +/- 6.9 in the Shen yang supplementing group, 18.3 +/- 3.6 in the Shen yin supplementing group, and 29.4 +/- 12.2 in the Shen yang and Shen yin supplementing group. The uterus VI (mg/100 g) was 183.4 +/- 11.6 in the normal control group,144.0 +/- 6.5 in the model group,158.7 +/- 6.3 in the Shen yang supplementing group,152.1 +/- 6.9 in the Shen yin supplementing group, and 172.8 +/- 8.1 in the Shen yang and Shen yin supplementing group. The ovarian VI (mg/100 g) were 32.9 +/- 2.4 in the normal control group, 22.6 +/- 1.1 in the model group, 25.0 +/- 1.4 in the Shen yang supplementing group, 23.0 +/- 0.4 in the Shen yin supplementing group, and 31.4 +/- 3.3 in the Shen yang and Shen yin supplementing group. Compared with the model group, the body weight and ovarian VI increased in the Shen yang supplementing group and the Shen yang and Shen yin supplementing group (P < 0.05, P < 0.01). The uterus VI increased in each medicated group (P < 0.05, P < 0.01). Compared with the Shen yang supplementing group and the Shen yin supplementing group, all indices increased in the Shen yang and Shen yin supplementing group (P < 0.05, P < 0.01). The E2 and P levels increased in the Shen yang supplementing group and the Shen yang and Shen yin supplementing group (P < 0.05, P < 0.01). The content of E2 (pg/mL) was 22.1 +/- 9.4 in the normal control group, 9.8 +/- 3.0 in the model group, 11.3 +/- 2.2 in the Shen yang supplementing group, 10.5 +/- 0.8 in the Shen yin supplementing group, and 16.0 +/- 5.5 in the Shen yang and Shen yin supplementing group. The content of P (ng/mL) was 14.6 +/- 7.5 in the normal control group, 4.3 +/- 1.8 in the model group, 8.3 +/- 2.8 in the Shen yang supplementing group, 5.9 +/- 2.9 in the Shen yin supplementing group, and 9.5 +/- 3.4 in the Shen yang and Shen yin supplementing group. Compared with the Shen yang supplementing group and the Shen yin supplementing group, the E2 level increased in the Shen yang and Shen yin supplementing group (P < 0.05, P < 0.01). Compared with the Shen yin supplementing group, the P level increased in the Shen yang and Shen yin supplementing group (P < 0.05). Compared with the model group, the ovarian follicle at each stage increased and pathological follicular ovarian follicles decreased in the Shen yang and Shen yin supplementing group (P < 0.01). Less primary follicles, secondary follicles, and mature follicles could be seen in the Shen yang supplementing group and the Shen yin supplementing group. The total numbers of all-level follicles were obviously higher in the Shen yang and Shen yin supplementing group than in the Shen yang supplementing group and the Shen yin supplementing group (P < 0.05). The number of pathological follicles was obviously less in the Shen yang and Shen yin supplementing group than in the Shen yin supplementing group (P < 0.05).CONCLUSIONSAs for SYDS, JSP and its dissembled recipes could improve damaged ovarian functions to some degree. But better effect could not be obtained by Shen yang supplementing method or Shen yin supplementing method alone. Shen yang and Shen yin supplementing method could elevate the efficacy.
