目的探索归肾丸对卵巢储备功能低下(DOR)小鼠卵巢Oct-4、MVH及Egr-1的影响。方法将40只C57BL/6J雌性小鼠随机分为正常组、模型组、归肾丸组和脱氢表雄酮(DHEA)组。连续序贯腹腔注射孕马血清(PMSG),人绒毛膜促性腺激素(HCG),前列腺素F2α(PGF2α)产生连续超数排卵,再结合臭氧吸入构建DOR模型。其后归肾丸组给予0.3 m L归肾丸中药灌胃,DHEA组给予0.3 m L DHEA灌胃,而正常组与模型组均给予相同剂量生理盐水灌胃,21天。采用ELISA法检测血清雌二醇(E2)、孕酮(P)和抗苗勒氏管激素(AMH)水平以及Real time-PCR检测Oct-4、MVH、Egr-1 mRNA的变化。结果与模型组比较,各治疗组血清E2、P及AMH水平均明显升高,ER、PR、MVH、Oct-4 mRNA表达均明显升高,差异有统计学意义(P<0.05)。结论归肾丸能改善DOR小鼠Oct-4、MVH、Egr-1 mRNA表达,改善卵巢功能。
The aim of the present study was to explore the effect and mechanism of Bushen Huoxue recipe(BHR) on ovarian reserve in mice with premature ovarian failure(POF). Mice were divided into 3 groups: normal group, model group and BHR group. Intraperitoneal injection of cyclophosphamide was performed to create the POF model. Primordial follicular(PDF) number, ovarian wet weight, ovarian index, and estrous cycle were analyzed to evaluate the effect of BHR on POF. Meanwhile, the m RNA and protein level of Mouse Vasa Homologue(MVH) in the bone marrow, peripheral blood and ovary were detected, to explore the underlying mechanism of the treatment efficacy of BHR on ovarian reserve. By the time of BHR treatment for 28 days, BHR increased the PDF number and shortened the estrous cycle of POF mice. BHR also decreased the m RNA level of MVH in the bone marrow, and increased m RNA and protein level of MVH in the ovary of POF mice. Our results demonstrated a treatment efficacy of BHR on POF mice, and revealed that BHR might repair the dysfunction of germline stem cells in the bone marrow, and thus to improve the ovarian reserve and enhance the ovarian function of POF mice through neo-oogenesis.
