1.Cell counting results showed that about 16% of the pituitary cells express Islet-1 at day 60 of gestation; Islet-1 immunopositive cell rate increased to 22% at day 90, which kept no significant change until day 120 of gestation; At the newborn, about 11% pituitary cells contained Islet-1 and thendecreased to 5.8% in the adult ewe.
细胞计数结果显示，妊娠60天的绵羊胎儿垂体中大约16％的细胞表达Islet-1，90天时升至22％，并持续到120天，新生羔羊垂体中约11％的细胞表达Islet-1，在成年母羊仅有约5.8％的垂体细胞表达Islet-1。
2.Purified T cells were isolated from spleen of the CBA/J females using magnetic beads at day 9 of gestation and labeled with 5 (and 6) carboxyfluorescein diacatate succinimidyl ester (CFSE) in vitro. The CFSE labeled T cells were intravenously injected into other CBA/J females mated with DBA/2 males at day 4 of gestation.
于孕 9天 ,应用免疫磁珠阴性分选两组孕鼠的脾脏T细胞 ,将T细胞进行碳氧氢化荧光素双乙酸盐琥珀酰亚胺酯 (CFSE)体外荧光标记 ,再分别过继转输至孕 4天的CBA/J×DBA/ 2孕鼠。
3.For rats of group A,HTO was intrap-eritoneally injected at the lst day of gestation(in the embryo period)andfor rats of group B,at the 13th day of gestation(in the fetus period)andthe dose of HTO injected was enough to keep a concentration of HTO of1.85 MBq(or 50μCi)per l mL of body water in animals.
A 组大鼠于妊娠第1d(胚胎期),B 组大鼠于妊娠第13d(胎儿期)经腹腔注入氚水,使动物体水氚放射性浓度达到1.85MBq/ml(50μCi/ml)。
4.SP—L and ENL—L fibers were initially observed by the 8th gestation week in the ILP) nucleus and positive fibers were expanded also inward along the intermediate zone at 9th—13th weeks of gestation.
SP—L和ENK—L阳性纤维最早见于第8周中间带的外侧份,位于套层与缘层之间,相当于ILP的原基部。 9～13周,阳性纤维亦向内延伸。
5.The presence of sperm in the vaginal smear signifies gestation day one. Eight pregnant rats were divided into experiment (5) and control (3) groups. Gavage with ethylenethiourea (ETU, 1% 125?mg/kg) and distilled water were carried out on gestation day 11 for experiment and control groups respectively.
雌雄交配后第 11d对实验组 5只雌鼠使用乙烯硫脲 (ethylenethiourea ,ETU)灌胃 (1%乙烯硫脲溶液 ,12 5mg/kg) ,对照组孕鼠在同一天使用等量蒸馏水灌胃。
6.Results In the cases with Hb Bart′s fetal edema syndrome,the heart was enlarged from 25 weeks′ gestation,right atrial enlargement came earliest, along with gestation weeks′ followed with right ventricle,left atrium and left ventricle aggravated enlargement.
结果 HbBart胎儿水肿综合征的心脏从妊娠中期 ( 2 5周 )开始增大 ,以右心房增大最早出现 ,此后随着孕周的增加而加重 ,继之右心室及左心房室增大 ;
7.Compared with the patients at 35～36 +6 week gestation, caesarean birth rate of the patients at 28～34 +6 weeks gestation was obviously lower (P
孕 2 8～ 34+ 6w 与孕35～ 36 + 6wPPROM比较 ,前者剖官产率明显低于后者 (P
8.This paper describes the isolation and partial characterization of EPF in the mixed sera of SO pregnancy women , between 3 and 8 weeks of gestation, EPF was purified with use of Ion - Exchange Chromatography, Sephades G-100 Gel Permeation , Disc-PAGE and SDS-PAGE. EPF activity was measured in all the serum samples and chromatogiaphic fractions using the rosette inhilition test. The results showed: 1. EPF is present in maternal scrum during carly hu-man gestation.
采用DEAE纤维素(Whatman产)柱层析Sephadex G-100凝胶过滤、聚丙烯酰胺凝胶圆盘电泳(Disc-PAGE)、SDS-聚丙烯酰胺凝胶平板电泳(SDS-PAGE)对50例妊娠3～8周妇女混合血清中早孕因子(EPF)进行纯化提取及部分特性研究,并采用花结抑制试验(Ea-RIT)检测EPF活性,结果表明:(1)EPF存在于早孕妇女血清中;
9.Results: During wich 16～38 weeks of gestation, AFI kept in pact with gestational weeks. After 38 weeks of gestation, AFI decreased as gestational weeks proceeded.
结果：妊16～38孕周随孕周增加AFI增加、38孕周以后，随孕周增加AFI下降。
10.Methods Color Doppler echocardiography was adopted to study 67 cases with Hb Bart′s fetal edema syndrome in different weeks′ gestation. Atrial and ventricular diameter and cardiac function were measured, and compared with those of normal fetuses in same weeks′ gestation.
方法 应用彩色多普勒超声心动图探测 67例不同胎龄HbBart胎儿水肿综合征的心脏各房室内径和心功能的相关参数值 ,并与同龄正常胎儿进行对照。
