锌与其它微量元素一样是人类不可缺少的营养成份。远在几世纪前锌就作为药物被利用,古埃及最先用炉甘石治病,后来氧化锌、硫酸锌、硬脂酸锌也逐渐用于治疗。四十多年前有的学者在实验中发现锌是哺乳动物必要的微量元素。五十年代的一些研究发现,肝硬变和急性心肌梗塞病人有锌代谢异常,同时也发现许多含锌的金属酶参与机体的物质代谢过程。近年的研究表明,锌不仅是正常生长发育、食欲、味觉和嗅觉所必需的元素,而且与某些疾病的发生、发展有密切关系。 Zinc and other trace elements are indispensable to human nutrition. As far back centuries ago, zinc was used as a medicine. Ancient Egypt was the first to treat calamine. Later, zinc oxide, zinc sulfate and zinc stearate were also gradually used for treatment. Some scholars more than forty years ago in the experiment found that zinc is a trace element necessary for mammals. Some studies of the 1950s found that patients with cirrhosis and acute myocardial infarction had abnormal zinc metabolism and that many zinc-containing metalloenzymes are involved in the body’s metabolic processes. Recent studies have shown that zinc is not only the normal growth and development, appetite, taste and smell essential elements, but also with the occurrence of certain diseases, the development is closely related.
