摘要: 为了研究我国云南引种玛咖的醇提取物对机体更年期内分泌激素水平的影响,本文采用自然衰老大鼠模型,随机分成低、中、高剂量组,阳性和阴性对照组,经过连续经口灌胃给予玛咖醇提取物90 d,测定了大鼠体重变化,比较了各脏器系数,分析了血清内分泌激素包括雌二醇(E2)、黄体生成素(LH)、卵泡刺激素(FSH)、睾酮(T)、孕酮(P)、垂体泌乳素(PRL)的水平。结果显示该玛咖醇提取物可降低更年期大鼠的体重,各干预组的肝脏、脾脏和肾脏系数显著高于阴性对照组;同时玛咖醇提取物可显著提高更年期大鼠血清T浓度,降低LH、P浓度(P<0.05);血清E-2、FSH、PRL浓度变化不显著(P>0.05)。推测玛咖醇提取物可能通过作用高级中枢调节机体分泌代谢,缓解更年期综合征症状。

Abstract: In order to study the effect of Lepidium meyenii (Maca) ethanol extract on endocrine hormone levels in blood serum of climacteric body,the naturally aged female rats were used as a model and randomly divided into low,medium and high dosage groups,positive and negative control groups.Maca ethanol extract were given to rats continuously by oral gavage for 90 days.The variations of body weight,organ index and endocrine hormone levels [serum estradiol (E2),luteinizing hormone (LH),follicle stimulation hormone (FSH),testosterone (T),progesterone (P) and pituitary prolactin (PRL)] in blood serum were then analyzed.As a result,the body weight was decreased by feeding with different dosages of Maca extract and the organ index of liver,spleen and kidney were higher than those of control group.The levels of T,LH and P in serum were significantly changed (P<0.05).The symptoms of menopause maybe alleviated by Maca ethanol extract through regulating the secretion and metabolism.

Key words: Maca, rat, climacteric syndrome, endocrine hormone
