Concentrations of chorionic somatomammotrophin (hCS) in maternal plasma at the time of delivery and in placental extracts were determined by radioimmunoassay and related to neonatal growth in 111 normal pregnancies. Mean maternal plasma hCS concentration was lower in association with small-for-dates infants, defined by either height or weight, than with well-grown preterm or term infants. Mean placental hCS concentration was not decreased in association with undergrown infants though placental hCS was correlated with maternal hCS (r=0 - 245).
采用放射免疫分析法测定了111例正常妊娠孕妇分娩时母血中绒毛膜生长催乳素（hCS）的浓度以及胎盘提取物中的hCS浓度，并将其与新生儿生长情况进行了关联分析。根据身高或体重界定，小于胎龄儿的孕妇母血hCS平均浓度低于发育良好的早产儿或足月儿。尽管胎盘hCS与母血hCS相关（r = 0 - 245），但小于胎龄儿的胎盘hCS平均浓度并未降低。
