Comparation of levels of the estrogen receptorβ in mainreproductive organ between the XO female individuals and the XX female individuals:Taking healthy mature female mandarin voles which are not in oestrum asexperimental animals, and they were measured with immuno-histochemical mehod.Experimental results indicated: the positive reaction of ERβin XO female individualsovaries was stronger than those in XX female individuals.

Methods1. Compared with adult female rats, aged female rats without oestrum were chosen by using RIA technology and sexual hormone was changed remarkably. Theses aged rats were divided into three groups（GNK group, HRT group and control group）. Treated them respectively with GNK, nilestriol and distilled water 3 months.

通过用阴道脱落细胞涂片检测发情周期的改变，放免法测定血清性激素的水平，与正常青年雌性大鼠比较，选择阴道脱落细胞无发情期改变，血清性激素水平有增龄性改变并且差异有显著性的老年雌性大鼠作为研究对象，分别用中药复方更年康和尼尔雌醇灌胃3个月，观察中药复方更年康对老年雌鼠的治疗作用。2。

本实验以大鼠为材料，利用原位杂交和免疫组化方法检测了basigin基因在大鼠早期妊娠、发情周期子宫中的表达；并利用假孕、延迟着床、人工蜕膜化及卵巢切除等模型研究basigin基因在大鼠子宫中的表达与调节。
