妊娠期的

The periparturient of manage、pregnancy、movement、nutrition and metabolism of non-milking and transition period、rumen-reticulum eyewinker、ravaged reticulum、blocked of abomasum pylorus ,are quite effected of DA.especially control of clinical or subclinical hypocalcamia、other diseases and DMI.

1、导致奶牛真胃变位发生的因素是多种多样的，其中受产前管理、妊娠、运动、干奶期和围产期的营养以及代谢、瘤—网胃异物、网胃创伤、皱胃幽门部阻塞等状况的影响，具有密切相关性。

To clarify the relationship between myelination and the expression of PSA-NCAM we systematically investigated its expression in the human forebrain from embryonic stage to midgestation (19-24 gestation weeks, gw).

为明确多聚唾液酸-神经细胞黏附分子的表达和髓鞘形成之间的关系，研究者系统地研究了从胚胎期到妊娠中期它在人前脑中的表达。

The efficiency of the nuclear transfer was 63.6%(63/99).Forty-seven clone embryos were transferred into 5 recipient goats. After embryo transfer, two recipient goats have not been seen oestrous within 2 oestrum, and one of the two recipient goats was examined positive by gravid testing, which testified the clone embryos were viable in the uterus of recipient goats.

阳性细胞克隆中的2株(M9，M10)已经进行了首次细胞核移植，核移植成功率为63.6％(63／99)，将47个发育较好的克隆胚胎进行了胚胎移植，共用受体羊5只，2只受体羊2个情期未见返情，在没有返情的2只受体山羊中有1只妊娠检测阳性，说明转基因克隆胚胚胎移植后在受体山羊体内发育良好。

Methods:By immunohistochemistry,expression and distribution of Foxp3 were observed in 27 cases of human endometrium (15 at proliferative phase and 12 at secretory phase )and 57cases of decidual tissues 32 of normal early pregnant women and 25 of unexplained recurrent spontaneous abortion...

Foxp3在分泌期子宫内膜和蜕膜组织的表达可能在胚泡植入和早期妊娠的维持中起重要作用，其表达水平降低可能与URSA的发生有关。

Results In dioestrous mice, many iNOS+ cells were found in the stroma of endometrium. There was no obvious differences between the immunized mice and the control mice. In the uterus on 3 day of pregnancy, however, there was obvious difference about the iNOS quantity in uterus between the immunized and the control mice. There was strong positive reaction on the epithelia of endometrium and the endometrial gland in the lamina propria in control mice, while the staining of iNOS in the uterus of SA-30 immunized mice was very weak, only a few of iNOS+ cells were observed in the myometrium.

结果 SA-30免疫后对间情期小鼠子宫内的iNOS没有明显影响，无论是免疫组还是对照组，在子宫内膜基质中均有大量阳性细胞分布，两者无明显差异；在妊娠第3d时，对照组的小鼠子宫中有较多iNOS表达，阳性标记主要集中在内膜上皮及固有膜中的子宫腺上，经SA-30免疫的小鼠子宫中，iNOS表达则显著减少，整个内膜标记极弱，只在子宫肌层内有少量iNOS阳性细胞分布。

结果 SA-30免疫后对间情期小鼠子宫内的iNOS没有明显瘙痒影响，无论是免疫组还是对照组，在子宫内膜基质中均有大量阳性偏瘫细胞分布，两者无明显瘙痒差异；在妊娠第3d时，对照组的小鼠子宫中有较多iNOS表达，阳性标记主要集中在内膜上皮及固有膜中的子宫腺上，经SA-30免疫的小鼠子宫中，iNOS表达则显著减少，整个内膜标记极弱，只在子宫肌层内有少量iNOS阳性偏瘫细胞分布。

Methods In total 148pregnant women were enro lled in this study. The e-chogenic feature and the blood flow i ndexesof the ovarian corpus luteum were ass essed from4th to 12th gestational week with tra ns-vaginal color Doppler ultrasono graphy.

方法采用经阴道超声检测148例早期妊娠4～12周孕妇的卵巢，观察卵巢内黄体的二维声像及彩色多普勒血流改变，检测收缩期最大峰值流速、阻力指数及搏动指数。

We suppose that there is a presently undefined subfraction of stem cell population that exists in a number of tissues beyond embryonic development. We term them postembryonic pluripotent stem cells. They differ from embryonic stem cells in that they gradually lose some differentiation potentials during development and adopt some special phenotypes once within a certain tissue. They can give rise to different kinds of stem cells; therefore, help to maintain balance during development and metabolism. They provide cells not only for the damaged tissues they reside, but also for damaged tissues different from them by migration triggered by proinflammatory cytokines or growth factors.

我们认为在胚胎发育后的多种组织中都存在一类原始干细胞群体，它们和造血干细胞、神经干细胞等多能干细胞不同，后者只能分化为特定胚层的细胞，而这类原始干细胞可分化为不同胚层的组织细胞；另一方面，它们区别于胚胎干细胞，在妊娠期间会逐渐失去部分分化潜能，并且会出现一些特殊表型或者分子标志，我们称其为胚胎后亚全能干细胞，这类干细胞具有下列特性：可分化为不同胚层的细胞，分布于身体的所有组织和器官，具有相同的表型或标志；他们在胚胎期存在于一些或全部的组织和器官中，可分化为不同类型的多能干细胞并在生长发育和新陈代谢中维持这些多能干细胞保持平衡；可以参与机体自我修复和更新，不仅能分化为所在器官的组织特异性细胞，参与器官重塑，也可以在炎症因子或者生长因子的趋化作用下，远处转移修复受损组织。

In situ hybridization using biotinylated POMC cRNA probe made it possible to localize POMC mRNA in the rat ovary. POMC mRNA predominantly existed in corpora lutea of diesturs, pregnant and pseudopregnant rat ovaries. POMC containing cells scattered in the ovarian intertitium were seen. The amount of POMC mRNA in granulosa cells was negligible.

采用生物素标记的POMCcRNA作为探针，进行原位杂文，研究POMCmRNA在大鼠卵巢中的分布，实验表明，POMCmRNA主要分布于间期，妊娠和假孕大鼠卵巢黄体中，间质细胞也可见少量POMCmRNA，而卵泡颗粒细胞中POMCmRNA极少。

Results The expression of endogenous LN was found in the basement membrane of epithelium, glands and blood vessels in uterine endometrium of both estrus and early pregnancy. And its was faint that LN present in basement membrane as the implantation occurs, but the LN immunostaining in the epithelial cells of endometrium was stronger. The exogenous LN has no obvious influence on blastocyst attachment and implantation. LN-antibody intra-uterine injection showed significant repressing effect on mouse blastocyst implantation.

结果 动情期及妊娠早期小鼠子宫内膜内源性LN在上皮和腺基膜及血管内皮基膜均有表达，并随着植入的发生基膜的LN表达减弱，而内膜上皮中LN免疫染色逐渐增强；外源性LN对小鼠胚泡粘附与植入子宫内膜不产生明显影响，层粘连蛋白抗体明显抑制小鼠胚泡着床。
