胎儿胎盘激素的测定,如胎盘催乳素(hPL)和雌三醇(E_3),对处理某些妊娠疾患者有一定价值。近来又有一些新的化验,如Schwangerscharfts蛋白1(SP_1)和与妊娠有关的血浆蛋白A和B(PAPP-A和PAPP-B)。随妊娠之进展,这些蛋白在母体血浆中的浓度也升高。为识别孕妇所处的危险程度,本研究拟比较一些胎儿胎盘功能试验的效用。作者所用方法,是随机选用妊娠34周志愿者的静脉血10ml,置于肝素化容器内,立即离心并储存于-20℃。PAPP-A和SP_1分别用Bischof等人(1979)和Bruce与Klopper(1978)所描述的免
Determination of fetal placental hormones, such as placental lactogen (hPL) and estriol (E_3), is of some value in the treatment of certain gestational conditions. Several new assays have been recently introduced, such as Schwangers- charfts protein 1 (SP_1) and pregnancy-associated plasma proteins A and B (PAPP-A and PAPP-B). As pregnancy progresses, the concentrations of these proteins in maternal plasma also increase. To identify the extent of the risk posed by pregnant women, this study intended to compare the usefulness of some fetal placental function tests. The method used by the authors was to randomly select 10 ml of venous blood from volunteers at 34 weeks of gestation, placed in a heparinized container, immediately centrifuged and stored at -20 ° C. PAPP-A and SP-1 are respectively as described by Bischof et al. (1979) and Bruce and Klopper (1978)
