巯基是构成酶蛋白的辅基,是辅酶之一,参与体內的代谢活动,具有重要的生物学意义。在一些工业毒物如铅、汞、苯、砷和四氯化碳等中毒时,其活性被抑制。因此,测定血清中巯基的总量,对某些职业病的早期诊断,有一定的价值。在这方面,国內有不少报道。近年来,我们试测了部分健 Sulfhydryl is a cofactor that constitutes the enzyme protein, is one of the coenzymes involved in the body’s metabolic activity, has important biological significance. In some industrial toxicants such as lead, mercury, benzene, arsenic and carbon tetrachloride poisoning, its activity is inhibited. Therefore, the determination of the total amount of thiol in serum, for some early diagnosis of occupational diseases, have some value. In this regard, there are many reports in the country.
