本文研究葡萄胎、部分葡萄胎及水泡样变性排空后血清HCG消退的时间。 HCG是种糖蛋白,由两条多肽链组成(α-和β-亚单位)。α-亚单位的免疫学和生物学特性与其他糖蛋白激素(FSH,LH,TSH)的α-亚单位相同。但β-亚单位是具不同激素生物学活性的特异部位。HCG由正常的和赘生的滋养叶组织产生。尿HCG量及血清浓度与滋养叶细胞的数量直接有关。葡萄胎病人与正常孕妇相比,血液中HCG含量和游离的β-亚单位的含量均增高。而α-HCG却正常或稍高。为了解血清HCG消退时间与存在的
This article studies hydatidiform mole, partial hydatidiform mole and blister-like degeneration after emptying of serum HCG time. HCG is a glycoprotein consisting of two polypeptide chains (α- and β-subunits). The immunological and biological properties of the α-subunit are the same as those of other glycoprotein hormones (FSH, LH, TSH). But β-subunit is a specific site with different hormone biological activity. HCG is produced by normal and neoplastic nodal tissue. Urinary HCG levels and serum concentrations are directly related to the number of trophoblastic cells. Compared with normal pregnant women, the content of HCG and free β-subunit in blood of hydatidiform mole patients are higher. Α-HCG is normal or slightly higher. To understand the time and presence of serum HCG regression
