【摘要】 用电感耦合等离子发射光谱法测定了104名孕妇及其新生儿血清和发中锌、铜、钙、磷,镁五种元素含量。结果发现,孕妇血清锌、钙和镁随孕期进展显著下降,血清铜和磷自孕早期开始就持续显著升高;脐血铜和磷低于母血,镁与母血一致,锌和钙都显著高于母血水平;孕期发锌、铜和磷变化不明显,钙和镁随孕期进展逐渐显著降低;除新生儿发铜显著低于母发外,锌、钙、磷和镁都高于母发含量。更多还原

【Abstract】 A longitudinal study was carried out on zinc, copper, calcium, phosphorus and magnesium status of 104 normal primigravidas. The five elements in serum and hair of the mothers and their newborns were estimated with inductive coupled plasma emission spectroscopy. The results showed that the concentration of serum zinc, calcium, magnesium decreased gradually while copper and phosphorus increased remarkably in the course of pregnancy. The serum copper and phosphorus of cord blood were lower, zinc and calcium were higher than that of mothers’ blood. The contents of hair zinc, copper, and phosphorus showed no differences but calcium and magnesium decreased gradually during pregnancy. Except that the level of copper in the newborns’ hair was much lower, other elements were much higher than that in the mothers’ hair.更多还原
