Plasma somatomedin activity was measured by postnatal pig cartilage bioassay in 11 full term normal for dates, 10 preterm normal for dates and 5 full term small for dates newborn infants on the 2nd, 5th and 10th day after birth. On day 2 mean somatomedin activity was lower than in the adult in all three groups of infants. After that, a slight but not significant rise in somatomedin activity occurred in the full term but not in the preterm infants. No significant correlation was found between somatomedin activity and calorie, protein, lipid or carbohydrate intake.
采用产后猪软骨生物测定法，对11名足月正常体重、10名早产正常体重和5名足月小样儿的新生儿在出生后第2天、第5天和第10天测定血浆生长调节素活性。在出生后第2天，三组婴儿的平均生长调节素活性均低于成年人。此后，足月婴儿的生长调节素活性有轻微但不显著的升高，而早产婴儿则没有。未发现生长调节素活性与热量、蛋白质、脂质或碳水化合物摄入量之间存在显著相关性。
