胚胎吸收

孕第14天比较两种模型各组的胚胎吸收率R。

The embryo resorption rate was counted at day 14 of gestation .

目的研究NOD/SCID孕鼠胚胎吸收率（Resorptionrate，RR）与母-胎界面局部免疫状况的关系。

Objective : To evaluate the relationship between the embryo resorption rate ( RR ) and the status of local immunity at the feto-maternal interface in pregnant NOD / SCID mice .

结果：实验组的胚胎吸收率和MMP-9均显著低于对照组（P＜0.05），与正常对照组间均无差异；

Results : The embryo resorption rate and the expression of MMP-9 in experimental group significantly were reduced compared with those in control group ( P < 0.05 ) and had no significantly difference from those in normal group ( P > 0.05 ) .

治疗组即CD86mAb干预组的胚胎吸收率为5.57%，与模型组比较，有显著性差异（P0.05），但与对照组无差异（P0.05）。

The treatment group was 17.35 % in the embryo resorption rate of pregnancy , There was significant differences between the treatment group and the model group ( P 0.05 ), but there were no differences between the treatment group and control group ( P 0 .

结论：在妊娠早期阻断CD86协同刺激分子能够通过某些机制诱导自然流产鼠MMP-9/TIMP-3的比值降低并且降低自然流产模型的胚胎吸收率，使模型组的胚胎吸收率恢复至正常妊娠水平。

Conclusion : Blockage of costimulatory signal CD86 at the early stage of gestation can induce the reduction of the ratio of MMP-9 / TIMP-3 by some mechanisms and reduce the embryo resorption rate in the abortion-prone model to that of normal pregnant level .

另计算15对CBA/J×DBA/2小鼠孕13d的胚胎吸收率，并用CD80-FITC和CD45-PE双色流式细胞术检测CD80细胞在母胎交界面的构成比。

In another 15 pairs of CBA / J × DBA / 2 breedings , resorption rate on day 13 of pregnancy were calculated and the proportion of CD80 + cells at the fetomaternal interface were determined by using two-color flow cytometric analysis , mainly stained with CD80-FITC and CD45-PE .

巨噬细胞毒素用于降低CBA/J×DBA/2小鼠胚胎吸收率

Reduction of embryo resorption with macrophage toxin in CBA / J × DBA / 2 mice

石菖蒲煎剂、槲皮素+乙酸龙脑酯药液、黄芩+白术及自拟中药组方流产率、胚胎吸收率低于噪音模型组。因此，自拟中药对噪音诱导小鼠流产具有一定保胎作用。

Gramineus decoction , quercetin + bornyl acetate liquid skullcap + Atractylodes and TCD rate of abortion , embryo resorption rate in the control group , noise-induced abortion miscarriage .

结论：母-胎界面过多的DX5+CD69+细胞浸润可能与CBA/J×DBA/2小鼠胚胎吸收有关。

Conclusion : Infiltration of excessive DX5 ~ + CD69 ~ + cells at the feto-maternal interface may be associated with recurrent embryo resorption in CBA / J × DBA / 2 mice .

目的：研究巨噬细胞毒素降低反复自然流产模型CBA/J×DBA/2小鼠胚胎吸收率的免疫机制。

Aim : To investigate the immunological mechanisms for the reduction of embryo resorption with macrophage toxin in CBA / J × DBA / 2 mice , as a model of recurrent spontaneous abortion .

辐射组死胎率和胚胎吸收率均较正常对照组增高，尤以雌鼠照射后14～28天受孕最明显，分别为对照组的52和38倍。

EMP irradiation also resulted in a significant increase in fetal death rate and embryo absorption rate compared with control group , especially in the late conception group , which was increased 5 2 and 3 8 times respectively .

结论：体内注射巨噬细胞毒素可以显著降低CBA/J×DBA/2小鼠母胎交界面活化型T细胞和某些巨噬细胞亚型的比率，并且这种变化与胚胎吸收率的下降相联系。

Conclusion : In vivo depletion of macrophages by silica pretreatment could reduce embryo resorption in CBA / J × DBA / 2 mice , which was associated with the decrease of activated T cell proportions and some subsets of macrophages .

杀女婴跟胚胎再吸收是现在研究的范围。

Female infanticide and fetal resorption are active areas of study .

打开腹腔，暴露子宫，观察子宫生长情况，记录胚胎着床数和发生胚胎吸收的死胚数。

Abdominal cavity was opened , exposing the uterus , and observation of uterine growth , and record the number of implantation of the embryo and the embryo resorption of the number of dead embryos .

暗示了在胚胎发育过程中，胚胎不是选择性地吸收利用卵黄蛋白颗粒中的某种或某些蛋白质，而是以卵黄蛋白颗粒为单位，一个个地吸收利用。

The result implicated that the silkworm did not utilize the yolk protein selectively by absorbing one or some certain proteins in the yolk protein grains , but maybe the silkworm absorbed the yolk protein grain as a whole one by one during embryo development .

各组试验鼠于孕第10d剖杀，记录胚胎发育情况、胚胎着床数和死胚数，计算试验各组的流产率、胚胎吸收率。

Each group of test mice sacrificed in pregnancy 10d recorded embryo development , embryo implantation number and number of dead embryos , and calculate the test groups , the abortion rate , embryo resorption rate .
