大鼠薄型子宫内膜模型的建立和鉴定

为探索宫腔注入无水乙醇建立薄型子宫内膜模型的可行性,将25只大鼠分3组:对照组(宫腔注入生理盐水),5分钟组(宫腔注入无水乙醇并贮留5 min),10分钟组(宫腔注入无水乙醇并贮留10 min),经测量子宫内膜变薄者为造模组,5分钟组有14个子宫内膜变薄,10分钟组无一例纳入造模组.免疫组织化学检测角蛋白、波形蛋白、血管内皮生长因子(vascular endothelial growth factor,VEGF)、雌激素受体α(estrogen related recep-tor alpha,ERα)的表达.结果发现5分钟组造模组与对照组单位内膜面积中角蛋白面积、单位间质面积中波形蛋白面积和子宫内膜中VEGF平均光密度差异有统计学意义(P<0.05),造模组与对照组子宫内膜ERα组织学积分无差异(P>0.05).表明宫腔注入无水乙醇并贮留5 min可以成功建立薄型子宫内膜模型,成功率为70%.

Establishment and Identification of Rat Thin Endometrium Model

To explore a novel method to establish a thin endometrium by injecting ethanol into the uterine cavity of rat.Twenty-five female SD rats were divided into three groups: control group(physiological saline were injected into cavities and kept for 5 min),5 minutes group(95% ethanol was injected and kept for 5 min) and 10 minutes group(95% ethanol was injected and kept for 10 min).The endometria which were thin-ner than that of the control group would be taken as a new group-model group,the others were control ...
