用无火焰原子吸收法对31名足月产婴儿,18名早产婴儿和12名先天畸形新生儿及他们母亲的发Mn(锰)含量进行了测定。先天畸形婴儿及母亲的发Mn含量明显低于足月产婴儿、早产儿及他们母亲的发Mn含量。除先天畸形婴儿与其母亲外,其它两组母亲的发Mn浓度显著高于她们的婴儿。结果提示:1.Mn缺乏可能与宫内畸形形成有关。2.Mn可能通过一种体内平衡机制提供给婴儿,主要取决于母亲Mn的营养状况,3.胎儿期母亲发Mn的分析可作为宫内畸形危险的一项可靠指标。调查对象分4组:1.31名足月产婴儿
The contents of Mn (Mn) in 31 full-term infants, 18 premature infants and 12 newborns with congenital malformations and their mothers were determined by flameless atomic absorption spectrometry. Congenital malformations of infants and mothers hair Mn content was significantly lower than full-term infants, premature children and their mothers hair Mn content. In addition to the congenital malformations of infants and their mothers, the other two groups of mothers with Mn concentrations were significantly higher than their infants. The results suggest: 1.Mn deficiency may be related to the formation of intrauterine deformities. 2. Mn may be provided to babies through an in vivo balance mechanism that depends primarily on the nutritional status of the mother Mn.3 An analysis of maternal fetal Mn may be used as a reliable indicator of intrauterine malformation risk. The subjects were divided into 4 groups: 1.31 full-term infants
