钙与镁在机体中都属于宏量元素.钙对于心脏、神经、肌肉、皮肤的健康有着重要的作用,是构成骨骼和牙齿生长的主要成分.钙离子具有促使细胞收缩,控制神经细胞兴奋性、凝血,维护电解质平衡等功能.镁离子则具有维持神经一肌肉系统功能的完整性,并在ATP酶、胆碱酯酶与胆碱乙酰化酶的反映中是一个必需的辅助离子.青少年头发中钙和镁的含量报道不一致,津金昌一郎的研究结果显示,钙、镁含量随着年龄的增长而下降,而Richard则指出头发中钙的含量随着年龄的增长而下降.本研究对广西玉林地区7～16岁男性青少年的身高和体重两项的体格发育指标结合头发中钙、镁含量的研究,结果显示:随着青少年生长发育,头发中钙、镁含量现出不断的变化,表现为第一突增期与第二突增期时,钙含量下降,突增期结束时钙含量出现逐步回升,而镁的含量在第一突增期表现平稳,第二突增期含量则增加.这一现象也正说明了钙和镁在体内的功能上相近,并处于相互竞争的
Calcium and magnesium are macro elements in the body.Calcium plays an important role in the health of the heart, nerves, muscles and skin and is the main component of the growth of bone and teeth.Calcium can promote cell contraction and control the excitability of nerve cells , Clotting, maintaining electrolyte balance, etc. Magnesium ions have the function of maintaining the integrity of the neuromuscular system and are an essential ancillary ion in the reflections of ATPase, cholinesterase and choline acetylase. The content of calcium and magnesium in the report is inconsistent, Jin-Ichiro Ichiro study results show that calcium and magnesium content decreases with age, while Richard pointed out that the hair calcium content decreased with age.This study of Guangxi Yulin The physical and mental development indexes of height and weight of 7 ~ 16-year-old male adolescents combined with the study of calcium and magnesium in hair. The results showed that with the growth and development of adolescents, the content of calcium and magnesium in hair changed constantly, During the first and second abrupt periods, the calcium content decreased, while the calcium content gradually increased at the end of the sudden increase period, while the content of magnesium showed in the first surge period Stable, the second sudden increase of the content is increased. This phenomenon is indicative of calcium and magnesium in the body is similar in function and in competing
