近年来的研究表明,体内自由基—过氧化脂质的生成与清除平衡失控(生成过量或机体抗氧化系统机能障碍),可引起组织细胞损伤,导致许多疾病的发生和发展。目前已有不少方法用于过氧化脂质(LPO)、抗氧化酶和抗氧化剂的测定,但测定总抗氧化活性(AOA)来评价体内抗氧化系统的强度,国内尚未见到报道。本文参考斯别克多尔等(1984)的方 In recent years, studies have shown that the balance of free radical-lipid peroxidation in the body is out of control (generation of excess or body antioxidant system dysfunction) can cause tissue cell damage, leading to the occurrence and development of many diseases. There are many methods for the determination of lipid peroxide (LPO), antioxidant enzymes and antioxidants, but the determination of the total antioxidant activity (AOA) to evaluate the strength of the antioxidant system in vivo, has not been reported in China.
