摘要。对31名出生后26周发育良好的早产儿进行了连续血清锌浓度测定。锌浓度从出生时的17.9 μmol (1.17 mg/1)（正常成人值）逐渐下降到6周龄时的8.9 μmol (0.58 mg/1)，尽管第二周后锌摄入量大于13.7 μmol (900 μg)/kg/天。16周龄后血清锌升高至10.7 μmol/dl （0.7 mg/1）。没有婴儿表现出缺锌的临床症状。这一数据可以作为参考，与其他早产儿的血清锌浓度进行比较，以帮助确定缺锌状态。
ABSTRACT. Serial serum zinc concentrations were measured in 31 relatively well, growing premature infants during the first 26 weeks of life. Zinc concentrations declined progressively from 17.9 μmol (1.17 mg/1) at birth (normal adult value) to 8.9 μmol (0.58 mg/1) at 6 weeks of age despite a zinc intake of greater than 13.7 μmol (900 μg)/kg/day after the second week of life. The serum zinc increased after 16 weeks of age to 10.7 μmol/dl (0.7 mg/1). No infant demonstrated clinical signs of zinc deficiency. This data may serve as a reference against which serum zinc concentrations in other premature infants may be compared in order to help define the deficiency state.
