电离辐射作用于体内水分子可产生自由基,引起脂质过氧化等物理化学反应.因而,清除自由基可以对电离辐射引起的机体损伤起到很大的防护作用,很多辐射保护剂剂具有较好的清除自由基效应从而发挥其辐射防护作用.本工作围绕近年来研究较多的几类重要抗氧化剂的自由基清除效应作一概述,主要包括了多糖类、酚类物质、激素类、维生素类等等.

Ionization radiation can generate free radicals in biological system, which could induce lipid peroxi-dation, biomacromolecule and biomembrane damage, lost of cell function, cell cycle disturbance, genetic mutation and so on. The scavenging free radicals can protect organism from radiation damage. Many radio-protective agents, such as amylase, hydroxyl-benzene derivatives, hormone, vitamin, have great abilities to protect organism from ra-diation via scavenging free radicals. In this paper, we mainly review the free radical scavenging effects of several kinds of radio-protective agents.
