摘要
目的:观察益肾Ⅰ方对多囊卵巢综合征(PCOS)大鼠胰岛素抵抗以及性激素的改善作用。方法:采用十一酸睾酮加绒促性素(HCG)建立PCOS大鼠模型,连续ig二甲双胍或不同剂量的益肾Ⅰ方6周,观察大鼠血清肿瘤坏死因子-α(TNF-α)、空腹血糖(FBG)、糖耐量(OGTT-2hBG)、胰岛素(Ins)含量和胰岛素敏感指数(ISI)、睾酮(T)、胰岛素样生长因子-Ι(IGF-1)、雌激素(E2)、孕酮(P)、泌乳素(PRL)的变化。结果:PCOS大鼠TNF-α,FBG,OGTT-2hBG和Ins水平以及T,IGF-1,E2和PRL含量明显高于对照组;ISI,P水平则显著降低(均P<0.01)。二甲双胍和益肾Ⅰ方3个剂量组均能不同程度地改善PCOS大鼠的上述病理改变(P<0.01~0.05),但益肾Ⅰ方低剂量组PRL和ISI未见明显改变(P>0.05)。结论:二甲双胍及益肾Ⅰ方均能不同程度地改善PCOS大鼠胰岛素抵抗以及性激素代谢异常。
Objective:To investigate effect of Yishen Yifang decoction on insulin resistance and sex hormone in rats with polycystic ovary syndrome(PCOS) . Method:The model of PCOS rats induced by testosterone undecanoate and human chorionic gonadotropin(HCG) ,afterwards metformin,different doses of Yishen Yifang decoction were taken by intragastric administration for 6 weeks. At the end the contents of fasting blood-glucose(FBG) ,2-hours blood glucose after oral glucose tolerance test(OGTT-2hBG) ,testosterone(T) insulin-like growth factor-Ι(IGF-1) ,estrogen(E2) ,progesterone(P) ,prolactin(PRL) ,insulin(Ins) ,tumor necrosis factor(TNF) -α were determined;the changes of insulin sensitivity index(ISI) were counted. Result:Compared with the normal group,the concentrations of FB,OGTT-2hBG,TNF-α,T,IGF-1,E2 and PRL were increased obviously(P〈0. 01) ,but ISI,P were decreased significantly(P〈0. 01) in model rats. metformin and Yishen Yifang decoction could improve the pathologic changes in PCOS rats(P〈0. 01 or P〈0. 05);but Yishen Yifang decoction the effects of low-dose group did not change P and ISI(P〉0. 05) . Conclusion:Metformin and Yishen Yifang de-coction can improve the pathologic changes,IR,sex hormone in PCOS rats.
