Abstract

Zinc concentration in cord plasma was determined in 148 healthy appropriate-for-gestational-age babies delivered at various gestational ages. Zinc concentration in cord tissue was also determined in 62 of these babies. There was a significant rise in the cord tissue zinc concentration just after the 35th week of gestational age; thereafter the levels remained relatively unchanged. The cord plasma zinc concentration decreased slightly with increasing gestational age, but these changes were not significant. There was a statistically significant positive correlation between cord tissue zinc concentration and birth weight. No correlation was found between cord plasma zinc concentration and birth weight or cord tissue zinc concentration.

摘要

对148名在不同孕周出生的健康适于胎龄儿的脐血血浆锌浓度进行了测定。其中62名婴儿还测定了脐组织锌浓度。孕35周后脐组织锌浓度显著升高；此后水平相对保持不变。脐血血浆锌浓度随孕周增加略有下降，但这些变化不显著。脐组织锌浓度与出生体重之间存在统计学上显著的正相关。未发现脐血血浆锌浓度与出生体重或脐组织锌浓度之间存在相关性。
