铜是广泛分布于体內的重要微量元素之一。早在150年前已知铜存在于动植物组织中,1931年首次报道了人类铜缺乏症。近几十年随着医学科学的发展,已更加注意到铜在人体内的重要性,以及铜与疾病的关系。 (一)铜的代谢 1.铜的含量与分布成人体内铜总量约80～150mg,二分之一分布在肌肉、骨中,肝、脑、心、肾、胰含量亦较高。最近有报道,白细胞中锌、铜浓度分别较红细胞约高7倍与10倍。成人铜的日需量2.0mg,6岁以下儿童为80μg/kg·日,7～10岁少年为40μg/kg·日。约30～40％的摄入铜在
Copper is one of the most important trace elements widely distributed in the body. As early as 150 years ago, copper is known to exist in animal and plant tissues and the first human copper deficiency was reported in 1931. In recent decades, with the development of medical science, more attention has been paid to the importance of copper in the human body and the relationship between copper and disease. (A) the metabolism of copper 1 copper content and distribution of adult body total copper about 80 ~ 150mg, one half of the distribution in the muscles, bones, liver, brain, heart, kidney, pancreatic content is also high. Recently it has been reported that leukocytes zinc and copper concentrations were about 7 times and 10 times higher than that of red blood cells. Adult daily demand for copper 2.0mg, children under 6 years of age was 80μg / kg · day, 7 to 10-year-old juvenile 40μg / kg · day. About 30 to 40% of intake of copper in
