The growth-promoting activity of serum was studied in 47 normal full-term newborns, comparing the effects of cord and of capillary serum upon the 3H-thymidine uptake into activated adult human lymphocytes. At birth the mean +/- SEM (TA) was significantly higher (P less than 0.001) in capillary serum (1.26 +/- 0.08 U/ml) than in cord blood (0.88 +/- 0.05 U/ml), the individual values being significantly correlated. The relatively low values in cord blood do not result from the presence of an inhibitor, nor from the cortisol levels. It may be concluded that study of cord blood is not the best means to measure growth-stimulating factors in newborns.
对47名正常足月新生儿的血清促生长活性进行了研究，比较了脐血血清和毛细血管血清对3H-胸腺嘧啶核苷摄入成人活化淋巴细胞的影响。出生时，毛细血管血清（1.26±0.08 U/ml）中的平均值±标准误（TA）显著高于脐血（0.88±0.05 U/ml）（P<0.001），个体值显著相关。脐血中相对较低的值并非由抑制剂的存在或皮质醇水平所致。可以得出结论，研究脐血并非测量新生儿生长刺激因子的最佳方法。
