发情的

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。

Contrary to the view that human estrus is cryptic, whether unadvertised, or "concealed," many cues can be used to distinguish between women who are close to ovulation and the same individuals at other times in the menstrual cycle.

The result showed that different concentration of FSH and LH were needed for sheep oocytes IVM in different season Xinjiang. FSH 12.9ug/ml,LH0.86IU/ml is proper to sheep oocytes IVM in summer-autumn anestrous period. FSH 8.6ug/ml,LH0.57IU/ml is proper to sheep oocytes IVM in autumn oestrous period.

结果表明：新疆绵羊卵母细胞在不同的季节中，体外成熟所需的FSH、LH浓度不同，夏秋乏情季节适宜于体外成熟的激素浓度为FSH 12.9ug/ml，LH0.86IU/ml；秋季发情季节适宜于体外成熟的激素浓度为FSH 8.6ug/ml，LH0.57IU/ml；春季乏情季节适宜于体外成熟的激素浓度为FSH 8.6ug/ml，LH0.86IU/ml。

The aim of this study was to investigate the expression of mPGES-2 protein in mouse oviduct during the early pregnancy, pseudopregnancy, and estrous cycle by immunohistochemistry and Western blot. The regulation of mPGES-2 protein in mouse oviducts was also studied under delayed implantation, steroid hormonal treatments and oviductal ligation.

本实验主要利用早期妊娠、假孕、输卵管结扎、发情周期、激素调节以及延迟着床等实验模型，结合免疫组织化学和Western blot 的实验方法，详细研究了mPGES-2 蛋白在小鼠输卵管中的表达与调节。mPGES-2 蛋白主要定位于不同时期的伞部和壶腹部的上皮纤毛细胞中，在伞部和壶腹部肌层以及峡部和宫管连接处的上皮和肌层中未检测到mPGES-2 蛋白的表达。
