外胎盘

The embryonic vessels failed to invade into the labyrinthine layer of placenta, which impaired the embryonic-maternal vascular connection. These defects could not be rescued by wild-type tetraploid blastocysts, excluding the possibility that they were due to the extraembryonic tissues.

组织免疫组化分析结果显示：毛细血管腔异常扩张，排列紊乱，不能形成大血管及细致有序的血管网络；胚外中胚层来源的卵黄囊脏层扁平上皮细胞形态变圆，与内皮细胞连接受损；胚胎血管不能侵入胎盘迷路层，胚体与母体血管连接受损。

Decreasing the gravidity and the times of curettage、avoiding delivery out of hospital and better supervision of antenatal care in the community studied are recommended to reduce obstetric hemorrhagic shock cases.

结果：产科失血性休克的发生率为0.65%，胎盘因素是失血性休克的主要原因；主要的危险因素是多次妊娠和流产、院外分娩及重度子痫前期。产科失血性休克导致的子宫切除率为17.6%。

Decidual tissue is a very complex and highly concordant tiny environment between mother and embryo during pregnancy, which is constituted of the variety cells such as extravi11ous trophoblast,endometrium cells, bone marrow cells, decidua l microphage,T cells and a few B cells and so on.

正常蜕膜组织是母-胎界面间一个非常复杂而又高度协调的微环境，它由多种细胞如侵袭至蜕膜的绒毛外滋养细胞(extravi11ous trophoblast，EVT)、子宫内膜源性细胞(如上皮细胞和血管内皮细胞)、骨髓源性细胞(如大颗粒淋巴细胞、蜕膜巨噬细胞、T细胞和少许B细胞)构成，这些细胞以及由这些细胞、母体和胎儿所分泌到蜕膜的细胞因子共同形成了母-胎间信息交流的平台，并对胚胎滋养细胞"有控性"侵袭、子宫内膜的免疫容受性、蜕膜化和胎盘的形成进行精细的调控。

The results were compared with control group. Results In group of ill pregnanted fetus, the contents of necessary nutrition elements in blood and tissue were all lower except that Fe in the group of congenital malformed foetus was high. The variation was especially evident in gravida's biood, umbilic blood, placenta, and liver of fetus. The contents of heavy metals such as Pb, Cd, Hg were all higher, and the variation was evident in placenta, liver of fetus and occipital bone.

结果 除先天性畸形胎儿组中的铁偏高外，其余血液及各组织中必需营养元素钙、锌、铜、铁、硒和维生素A含量普遍偏低，在母血、脐血和胎盘及胎儿肝脏中差异显著(P.05)；重金属铅、镉、汞含量普遍较高，在胎盘、胎儿肝脏和枕骨等组织中差异显著(P.05)。

The blood samples were collected at day 1 before and after the caprine placenta peptide were given for 10 days, and the number of the white blood cell and the ANAE+ in periperal blood ,the content of the globulin, the activity of lysozyme, the T-Aoc ,the activity of the GSH-Px and SOD, and the content of the MDA in serum were determined .

在口服羊胎盘肽的前1d和连续口服羊胎盘肽10d后的第1d各组采血样一次，测定外周血白细胞数、ANAE+淋巴细胞百分率、血清球蛋白含量、血清溶菌酶活性、血清总抗氧化能力、血清谷胱甘肽过氧化物酶活性、血清超氧化物歧化酶活性及丙二醛含量。

Their relative molecular weights were 4785 and 4386 respectively. And their absorbance peaks were 210.5 nm and 225.4 nm respectively. The bovine and caprine placental peptides could improve immunosuppressive T lymphocyte transformation rate. The immunosuppressive lymphocyte transformation rates in groups with the bovine placental peptide of 1:1×10^3 and 1:1×10^4 (P.05)and with the caprine placental peptides of 1:1×10^2, 1:1×10^3 and 1:1×10^4 (P.01 )increased more remarkably than that in immunosuppression group.

结果 从牛和羊胎盘中成功提取出了胎盘肽，其相对分子质量分别为4785和4386；其最大吸收峰分别为210.5和225.4nm；牛和羊胎盘肽均可使顺铂抑制的兔外周血T淋巴细胞的转化率显著提高，其中牛胎盘肽以1：l×10^3、1：l×10^4 2组吸收度明显高于抑制组(P.05)；羊胎盘肽以1：1×10^2、1：1×10^3和1：1×10^3 3组效果最为明显(P.01)。

MethodsThe distilled bovine and caprine placental peptide s were prepared by ultrafiltering and their relative molecular weights were mensurated by improved Tricine-SDS-PAGE eletrophoresis with urea.

结果从牛和羊胎盘中成功提取出了胎盘肽，其相对分子质量分别为4 785和4 386；其最大吸收峰分别为210.5和225.4 nm；牛和羊胎盘肽均可使顺铂抑制的兔外周血T淋巴细胞的转化率显著提高，其中牛胎盘肽以1∶1×103、1∶1×1042组吸收度明显高于抑制组(P.05)；羊胎盘肽以1∶1×102、1∶1×103和1∶1×1043组效果最为明显(P.01)。

We have performed systematical studies on intrauterine transmission of hepatitis B virus and our studies suggested that HBV may occur through progressive infection of different placental layers until the virus reaches the fetoplacental circulation, which is the named "transplacental cellular traffic" except through placental tears with transfusion of infected maternal blood into the fetal circulation, which is the named "hematogenous transmission".

我室近年来对HBV宫内传播进行了系列研究，发现了胎盘在宫内传播中的作用，并提出了HBV宫内传播机制的假设：除血源性途径外，还可通过HBV在胎盘组织内的&细胞传递&途径，即HBV可以从母体蜕膜细胞通过&逐层转移&至胎儿绒毛毛细血管内皮细胞，导致胎儿感染。

The 40 included articles involved mesenchyma stem cells obtained from marrow, muscle, the navel blood, placenta, peripheral blood, adipose tissue, vessel and so on.

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
