电离辐射通过水的辐解作用可产生出各种自由基 ,并可由自由基引发脂质过氧化反应影响生物膜的结构与功能并进而影响整个细胞的功能。超氧化物歧化酶 (ＳＯＤ)作为机体抗氧化酶系的一种 ,在防御氧的毒性、抗辐射损伤、预防衰老以及细胞间信号传导等方面具有重要作用。我室多年来
Ionizing radiation can produce a variety of free radicals through the radiolysis of water and can affect the structure and function of the biofilm by the free radical-initiated lipid peroxidation and further affect the function of the whole cell. As a kind of antioxidant enzyme system, superoxide dismutase (SOD) plays an important role in the defense of oxygen toxicity, anti-radiation damage, prevention of aging and cell-cell signal transduction.
