围产期的锌、铜代谢一、孕母锌、铜代谢:动物实践和临床观察均表明:孕母血浆锌浓度有逐渐下降的趋势。血浆锌约60～85％是与白蛋白结合的,故低蛋白血症往往有低血锌表现。孕早期血浆容量剧增,导致相对性低蛋白血症,这可能是孕早期母体血浆锌浓度下降的基本原因。此时即使增加锌供给量也难以纠正,说明母体血锌浓度下降非病理状态。但血锌持续低于50～55μg％则提示体内缺锌。
Perinatal zinc and copper metabolism, pregnant mother zinc, copper metabolism: Animal practice and clinical observations have shown that: maternal plasma zinc concentration gradually declining trend. About 60 ~ 85% of plasma zinc is combined with albumin, so hypoalbuminemia often have low blood zinc performance. Early pregnancy plasma volume surge, leading to relative hypoproteinemia, which may be the maternal plasma zinc concentration in early pregnancy decreased the basic reason. At this point even if the increase in the supply of zinc is also difficult to correct, indicating that maternal serum zinc concentration decreased non-pathological state. However, continuous lower blood zinc 50 ~ 55μg%, suggesting that zinc deficiency in the body.
