胎儿

Imprinted genes, with their key roles in controlling feto-placental nutrient supply and demand and their epigenetic lability in response to nutrients, may play an important role in adaptation/eolution.

有印记的基因、这种基因在控制胎儿胎盘营养供给和需求中的重要作用及其对营养响应的表遗传易变性，在适应环境和进化过程中可能起重要作用。

Methods: Separate and abstract the effective components of Huangqi (Omni-Saponin、total-flavone) and Danshen (Danshen-ketone、 Danshen-Quinone). Applying L-Arginine methyl ester to pregnant rats by I. P to make Nitrogen Oxide Synthesis blocking models (uterus-placenta-fetus lacking blood and oxygen model or pregnant hypertension syndrome model). On day 12, 18 of pregnancy paunched the rats and took out the fetus and placenta/uterus. Measured the basal BP during pregnant period and BP、protein、basal activity each day. Observed placenta/deciduas ultramicroscopic structure by electron microscope and took count of languishment cells. Measured the expressive intensity of bcl-2、Bax of placental nutrient cells by SABC method.

一氧化氮合成酶阻滞剂L-精氨酸甲酯妊娠大鼠腹腔给药，制作一氧化氮合成阻滞模型（子宫-胎盘-胎儿缺血缺氧或妊娠高血压模型），妊娠第12、18天剖腹取胎、胎盘／子宫，妊娠期测基础血压，每日测血压、蛋白质量、基本生理活动；电镜观察胎盘／蜕膜超微形态结构，并进行细胞凋亡计数；免疫组化检测胎盘滋养细胞bcl-2、Bax表达强度；原位杂交法检测胎盘滋养细胞、血管内皮细胞VEGF、eNOS、iNOS、MCP-1、MMP9（基质金属蛋白酶9）mRNA表达。

Before the baby is born, its whole body is covered with downy hair called lanugo.

出生前的胎儿全身覆盖着茸毛一样的毛，叫胎毛。

In the summer of 2006, Alison Lapper will be replaced for a further 15 months by an architectural model of sheets of Perspex designed by the German artist Thomas Schutte, and called, with heavy humour, Hotel For The Birds.

拉珀尔的母亲也是一位单身妈妈；还在怀孕的时候，丈夫就抛弃了她和腹中胎儿。

The use of Rh immune globulin to prevent the disease in babies of Rh negative mothers has become standard practice, and the disease, which used to claim the lives of 10,000 babies each year in the US alone, has been virtually eradicated in the developed world. In 1980 Drs. Pollack, Gorman, Freda, and Finn shared the Albert Lasker Award for their work on Rh disease.

使用Rh免疫球蛋白来预防在Rh阴性血型的母亲的胎儿的疾病，成为一种常规做法，这种曾经仅在美国每年夺走10，000名婴儿生命的疾病，在发达国家几乎被摧毁了。1980年，博士波拉克，戈尔曼，弗里达，芬恩由于他们在Rh疾病上的工作分享了亚伯雷斯克奖。

As America's government prepares to take a sudden and historic leftward turn, this might seem an odd moment to ponder what a conservative country it is.

一项大型调查研究表明，妇女在怀孕期间偶尔饮酒不会对胎儿造成伤害，相反孩子可能会受益于此。

Umbilical cord of normal length is about 50 cm, if there is cord around neck ring, the general would not experience too much of fetal risk.

正常的脐带长度是50公分左右，如果有脐带绕颈一圈，一般胎儿都不会有太大的危险。

The long-term inhalation lf harmful gas such as formaldehyde,benzene,xylene given off from the coatings may harm the immune system and cause leucocythemia,They are especially sensitive to women and children,Pregnant women inhaling benzene may cause malformed baby or abortion .

涂料中的甲醛、苯、二甲醛等释放出的有毒气体，长期吸入人体会损害人体免疫功能，导致白血病，尤其妇女、儿童最为敏感，而孕妇吸入苯会导致胎儿畸形或流产。
