微量元素可影响脂质过氧化和自由基清除的发生、发展和结局。苯能使大鼠脂质过氧化作用增强,铁可进一步增强苯的这一作用;苯使SOD活性增高。为补充人体这方面的资料,我们对苯作业工人血清MDA含量、红细胞SOD活性和头发10种金属元素含量进行了检测,结果报道如下: Trace elements can affect the occurrence and development of lipid peroxidation and free radical scavenging. Benzene can increase lipid peroxidation in rats, iron can further enhance the role of benzene; benzene to SOD activity increased. In order to replenish the human body in this respect, we detected the content of serum MDA, the activity of erythrocyte SOD and the content of 10 kinds of metal elements in the hair of benzene workers. The results are reported as follows:
