Trace elements in serum and growth in low birth weight infants

据了解，低出生体重儿出生时就处于微量元素不足的状态。本研究旨在通过对低出生体重儿血清中微量元素浓度的分析，明确低出生体重儿婴儿期对微量元素的需求，并与正常出生体重儿进行对比研究。由于分析了血清中的密度，除了镁和磷以外的元素也承认了这种差异。此外，还明确了微量元素浓度随滋补方法的不同而变化的规律。

The low birth weight infant is known to be born in the state of insufficiently of trace elements. The purpose of the present study is a thing to clarify the requirement of the trace element in low birth weight infant's infancy by analyzing the density in the serum of the trace elements making comparative study with the normal birth child. The difference was admitted with elements other than magnesium and phosphorus as a result of analyzing the density in the serum. Moreover, the thing that the density of the trace element changes by the difference of the method of nourishment became clear.
