The element content of the fingernails of 10 term and 14 preterm infants, clipped for the first time after delivery, was determined by x-ray microanalysis. The results showed a decrease in sulfur and aluminum, and a higher chlorine content in term infants in comparison with preterm ones, the difference being statistically significant. Sodium, potassium, calcium, and zinc content did not differ in the two groups. Copper, iron, magnesium, aluminum, and phosphorus were detected in trace amounts only. Cobalt was not detected in the fingernails of newborns in either group. The elevated content of aluminum in the fingernails of preterm infants may be a clue to the osteopenia observed in these infants.
对10名足月儿和14名早产儿出生后首次剪下的指甲进行了元素含量测定，采用X射线微量分析法。结果显示，与早产儿相比，足月儿指甲中的硫和铝含量降低，氯含量更高，差异具有统计学意义。两组的钠、钾、钙和锌含量无差异。仅检测到微量的铜、铁、镁、铝和磷。两组新生儿的指甲中均未检测到钴。早产儿指甲中铝含量升高可能是这些婴儿出现骨质减少的一个线索。
