锌是人体必需的14种微量元素中最重要的一种,近年来的研究表明,锌及乎涉及所有细胞代谢,现已知同80种酶的组成和代谢有关。在儿科范围内,它不仅是机体生长发育和功能所必需的元素,而且与某些疾病的发生、发展有密切关系。一、锌的代谢与生理作用 (一) 人体内锌的含量和分布:正常成人体内含锌总量为2～2.5克,其中60％分布于肌肉,30％分布于骨骼。人体内含锌浓度最高的器官是眼睛、皮肤、毛发、
Zinc is the most important of the 14 trace elements essential to the body. In recent years, studies have shown that zinc is involved in all cellular metabolism and is known to be involved in the composition and metabolism of 80 enzymes. In pediatrics, it is not only the necessary elements of the body’s growth and function, but also with the occurrence and development of certain diseases are closely related. First, the metabolic and physiological effects of zinc (a) the content and distribution of zinc in the body: the normal adult zinc content of 2 to 2.5 grams, of which 60% distributed in the muscle, 30% distributed in the bones. The highest concentration of zinc in human organs is the eyes, skin, hair,
