为了探索氧化与抗氧化失衡与肺癌的关系,本文采用放射免疫法及硫代巴比妥酸荧光法,分别检测了32例肺癌,30例慢性肺部疾病患者和20例健康人的血清超氧化物歧化酶(SOD)和脂质过氧化物—丙二醛(MDA)的含量.结果显示:肺癌组与非癌组和健康人组比较,SOD和MDA均具有显著性差异.提法氧化与抗氧化失衡与肺癌的发生有一定的关系,为肺癌的诊断和治疗提供了一定的依据. In order to explore the relationship between oxidation and antioxidant imbalance and lung cancer, we used radioimmunoassay and thiobarbituric acid fluorescence method to detect serum hyperoxidation in 32 lung cancer patients, 30 chronic lung disease patients and 20 healthy individuals, respectively. The contents of dismutase (SOD) and lipid peroxide-malondialdehyde (MDA) were found. The results showed that there were significant differences in SOD and MDA between lung cancer group and non-cancer group and healthy group. Antioxidation imbalance has a certain relationship with the occurrence of lung cancer, which provides a certain basis for the diagnosis and treatment of lung cancer.
