本世纪７０年代，人们即已发现汞离子与机体蛋白质中巯基有特殊亲和力，从而可导致体内数十种含巯基酶失活或膜功能紊乱，并认为可能为汞慢性毒性作用的基础［１］。镁是体内３００多种酶的辅助因子，是很多参与ＡＴＰ代谢的物质生化反应之关键因子［２］。近年实验证实，...
In the seventies of this century, it has been found that mercury ions have a special affinity for mercapto groups in the body proteins, which can lead to the inactivation of dozens of sulfhydryl-containing enzymes in the body or disorder of membrane function, and may be the basis for the chronic toxicity of mercury [1] . Magnesium is a cofactor for more than 300 enzymes in the body and is a key factor in many biochemical reactions involving ATP metabolism [2]. Experiments in recent years confirmed that ...
