超氧化物歧化酶(SOD)的功能是催化体内超氧自由基的歧化反应,对抗体有保护作用.近年来研究表明,超氧自由基与人类的健康及疾病,尤其是在抗衰老过程中有十分密切的关系.检测SOD的方法不少,均有不足之处.作者于1992年10月采用放射免疫分析法,检测不同年龄组的血清SOD,并进行了统计学分析,结果显示,人体内SOD与年龄密切相关,现报道如下. The function of superoxide dismutase (SOD) is to catalyze the disproportionation reaction of superoxide radicals in vivo, which has the protective effect on the antibody .Recent studies have shown that superoxide radical and human health and disease, especially in anti-aging process There is a very close relationship between the detection of SOD many ways, all have shortcomings.The author in October 1992 using radioimmunoassay, detection of serum SOD in different age groups and conducted a statistical analysis, the results show that people In vivo SOD and age are closely related, are reported below.
