硫醇和二硫化物的放射防护作用机制还没有共同的一致意见,虽曾提出一些学说,但没有单一机制能解释所有的观察。这些防护剂都是有毒的,在机体一些组织中引起紊乱。这种“生化休克”从生理学上已有很完善的描述,但在生化与酶学水平的描述还少。 There is no common agreement on the mechanisms of radioprotection of thiols and disulfides, although some doctrines have been proposed, but no single mechanism can explain all the observations. These protectants are toxic and cause disruption in some tissues of the body. This “biochemical shock” has a well-described physiology, but biochemical and enzymatic level is still described.
