抗氧化

Methods The activity of superoxide dismutase ( SOD), glutathione peroxidase ( GSH Px), the contents of hydrosulfide group ( SH) and malondialdehyde ( MDA) in the blood of patients were measured and analysed.

方法对燃煤型砷中毒患者体内抗氧化物质超氧化物歧化酶（SOD）、谷胱甘肽过氧化物酶（GSH-Px）、巯基（-SH）以及脂质过氧化代谢产物丙二醛（MDA）的含量进行了测定和分析。

As results, when being oxidation, the cyclohexane had best performance of antioxidation among the hydrocarbons investigated, while tetralin and butyl benzene had the poor.

结果表明，在氧化反应中，环己烷的抗氧化性能最好，抗氧化性能最差的是四氢萘和正丁苯；

Exogenous ascorbic acid or endogenous glutathione ( GSH) could increase cell activity, resist to cadmium in Cd-stressed Saccharomyces cerevisiae treated with cadmium, reduce the degree of oxidative damage of cadmium stress on yeast cells and restor the activity of antioxidant to some extent.

加入外源抗氧化剂维生素C或提高内源抗氧化剂谷胱甘肽（GSH）能够提高细胞对镉的抗性，降低镉胁迫对酵母细胞产生的氧化损伤，一定程度上恢复镉对抗氧化酶活性的抑制。
