本研究已最终确定了 21 天哺乳期早产母乳中 Zn、Cu、Cr、Se、Mn、F、Mo、Ni 和 B 的含量。通过电感耦合等离子体原子发射光谱 (ICP-MS) 分析微量元素 (TE) 含量，早产奶中观察到的 Zn、Cu、Cr、Se、Mn 和 F 的中位浓度与足月奶中的水平相比没有表现出显着差异。各个哺乳阶段的早产奶中钼、镍和硼含量均存在统计学显着性差异 (p < 0.05)。婴儿血液中的 TE 含量表明早产儿的钼浓度显着 (p < 0.01) 低于足月儿。在早产儿和足月新生儿的血液中获得了类似的其他 TE 含量值。这些发现表明需要对婴儿喂养中钼含量的现有膳食建议进行大量重新评估。
The present study has been finalized to perform the content of Zn, Cu, Cr, Se, Mn, F, Mo, Ni, and B in the preterm human milk over 21 d of lactation. Trace element (TE) contents were analyzed by inductively coupled plasma atomic emission spectroscopy (ICP-MS), and median concentrations of Zn, Cu, Cr, Se, Mn, and F observed in preterm milk did not demonstrate significant differences in comparison to levels shown in term milk. A statistical significant difference (p < 0.05) has been found among Mo, Ni, and B content in preterm milk for every stage of lactation. TE content of infant blood founded concentrations of Mo in preterm babies significantly (p < 0.01) lower than in term offsprings. Similar values of other TE content were obtained in blood of preterm and term newborns. These findings point to the need for a considerable reassessment of the existing dietary recommendation for Mo content in infant feeding.
