微量元素铜对眼的作用早为人们所关注,近年来随着微量分析技术的发展,人体有关铜的基础研究方取得进展。微量元素铜是人体不可缺少的元素,具有特殊的生理和生化的作用。铜常以某些酶的重要成分而存在,并与细胞活动有密切关系。铜元素缺乏或过量时常显示相应组织的功能和结构的异常。微量元素铜的研究对了解眼组织的正常成分,眼的某些重要功能,阐明眼病的发病机理有十分重要的意义。铜元素的定量测定已作为某些眼病的诊断依据,或作为一些眼病的早期手术和预后的可靠指标。现就所见之文献资料综述如下。一、铜代谢及组织分布铜在自然界分布甚广,人自食物中每日摄取2.5～5mg铜。主要来自肉食,经消化道吸收进
The role of trace elements of copper on the eye as early as people’s attention in recent years with the development of micro-analysis technology, the human body made progress on basic research on copper. Trace elements copper is an indispensable element of the human body, has a special physiological and biochemical effects. Copper often exists as an important component of certain enzymes and is closely related to cell activity. Copper deficiency or excess often shows the corresponding tissue function and structural abnormalities. The study of trace elements copper to understand the normal components of the eye tissue, some important eye function, clarify the pathogenesis of eye disease is of great significance. Quantitative determination of copper has been used as a diagnostic basis for some eye diseases or as a reliable indicator of early surgery and prognosis of some eye diseases. Now see the literature summarized as follows. First, the metabolism of copper and tissue distribution Copper is widely distributed in nature, people daily intake of food from 2.5 to 5mg of copper. Mainly from the meat, absorbed into the digestive tract
