自由基与肿瘤的关系已日益引起人们的重视，在病理情况下，体内常存在自由基代谢紊乱，自由基对组织细胞有很强的破坏作用，是肿瘤的发病基础。脂质过氧化物（LPO）在体内多少，反映了氧自由基对细胞膜性结构的氧化程度，并反映体内脂质氧化物的速度和强度，超氧化物歧化因（SO The relationship between free radicals and tumors has increasingly attracted people’s attention. In pathological conditions, there are often free-radical metabolic disorders in the body, and free radicals have a strong destructive effect on tissue cells, which is the basis for the onset of cancer. The amount of lipid peroxidation (LPO) in the body reflects the extent of oxidation of cell membrane structures by oxygen free radicals, and reflects the rate and intensity of lipid oxides in the body, and the cause of superoxide dismutation (SO).
