近年来,有关宏量和微量元素在机体生命活动过程中的作用引起研究者极大的关注。大量的工作证明,宏量和微量元素对维持体内化学环境的恒定是必需的。它们在分子、细胞和组织水平上参与机体重要的生化过程,作为多种酶活性中心的组成成分,同时多种疾病(镰状细胞贫血、肢皮炎肠病等)的发病机理同体内宏量和 In recent years, the role of macroscopic and trace elements in the life activities of the living body has drawn great attention of researchers. Extensive work has demonstrated that macroscopic and trace elements are necessary to maintain a constant chemical environment in the body. They are involved in important biochemical processes at the molecular, cellular and tissue levels as components of many enzyme active centers, and the pathogenesis of various diseases (sickle cell anemia,
