镁在细胞内阳离子中占第二位,对能量的产生和输送、蛋白质合成、肌肉收缩、神经兴奋都是很重要的,并且在很多酶系统中亦是重要的辅助因子。在75例因电解质紊乱所致的新生儿抽搐中,Cockburn等发现53％是由于镁缺乏。因抽搐仅是幼儿镁缺乏所致许多症状之一,以致镁缺乏常被忽略。 Magnesium is second in the intracellular cation and is important for energy production and delivery, protein synthesis, muscle contraction, and nerve excitation, and is also an important cofactor in many enzyme systems. In 75 cases of neonatal seizures due to electrolyte imbalance, Cockburn et al. Found that 53% were due to magnesium deficiency. Because convulsions are only one of many symptoms of childhood magnesium deficiency, magnesium deficiency is often overlooked.
