Trace elements in serum and growth in low birth weight infants

低出生体重儿是在微量元素缺乏的状态下出生的。本文通过对低出生体重儿血清微量元素浓度的分析，并与正常出生儿进行比较研究，以阐明低出生体重儿婴儿期微量元素的需要量。通过分析血清中的浓度，承认了除镁和磷以外的元素的差异。此外，微量元素浓度随营养方法的不同而变化的现象也变得清晰起来。

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.
