滋养层细胞能产生妊娠特异蛋白,因此可作为孕期胎盘功能的标志,同样亦可作为妊娠滋养叶疾病的标志。本文提出妊娠特异蛋白包括(a)绒毛膜促性腺激素(HCG);(b)胎盘催乳素(hPL);(c)妊娠特异糖蛋白(SP1);(d)胎盘蛋白5(PP5);(e)妊娠相关血浆蛋白 A(PAPP-A)。HCG 在处理滋养叶疾病中最重要,临床应用最广泛。HCG提供一种最有价值的标志,这是其它妊娠蛋白不能代替的。但某些病例,HCG 并不能完全反映疾病的全过程,因而常常需要其它妊娠蛋白作用为辅助标志。绒毛膜促性腺激素(HCG)HCG 是第一个被发现的妊娠特异蛋白,由合体细胞产生,排卵后8天即可在每体测出。妊娠第八周上升达高峰后迅速下降,在
Trophoblast cells can produce gestational-specific proteins, so it can be used as a marker of placental function during pregnancy, also can be used as a sign of pregnancy trophoblastic disease. This article proposes that gestational-specific proteins include: (a) chorionic gonadotropin (HCG); (b) placental lactogen (hPL); (c) gestational-specific glycoprotein e) Pregnancy Associated Plasma Protein A (PAPP-A). HCG in the treatment of nourish the most important disease, the most widely used clinical. HCG offers one of the most valuable signs that other pregnancy proteins can not replace. However, in some cases, HCG does not fully reflect the whole process of the disease and thus often requires the help of other gestagens as a secondary marker. Chorionic Gonadotropin (HCG) HCG is the first pregnancy-specific protein that has been found to be produced by syncytial cells measured on each body eight days after ovulation. After the eighth week of pregnancy rose rapidly reached the peak, at
