我们在1982年5～6月间,对在我院产科住院分娩的产妇,随机抽取正常足月产新生儿脐带混合血30例(男婴13例,女婴17例)以了解脐血中雌二醇(E_2)、孕酮(P)、睾酮(T)、皮质醇(F)、甲状腺素(T_4)、人绒毛膜促性腺激素(HCG)及HCG-β亚单位的浓度。现将检验方法及结果报告于下。血清T_4:用竞争性蛋白结合分析法测定,由北京原子能研究所提供药盒;血清HCG、HCG-β测定:用上海生物制品所提供的双抗体HCG与HCG-β放射免疫药盒;血浆E_2、
We from May to June 1982, in our hospital obstetrics and gynecology hospital delivery, randomly selected normal full-term neonatal umbilical cord blood mixed in 30 cases (13 cases of baby boys, 17 girls) to understand the umbilical cord blood in the female (E2), progesterone (P), testosterone (T), cortisol (F), thyroid hormone (T_4), human chorionic gonadotropin (HCG) and HCG-β subunits. Now test methods and results reported below. Serum T_4: determined by competitive protein binding assay, provided by the Beijing Institute of Atomic Energy Kit; serum HCG, HCG-β determination: Shanghai biological products provided by the dual antibody HCG and HCG-β radioimmunoassay; plasma E2 ,
