摘要

氧自由基无疑参与了许多病理状态的发展。然而,考虑到在生物进化过程中,氧自由基的产生是为了在细胞代谢中发挥有用的作用而被选择的可能性;本文简要回顾了关于这一主题的以往数据。提出了“氧自由基循环”的概念,作为一个有用的理论模型。

Oxygen radicals, a failure or a success of evolution?

Oxygen radicals are no doubt involved in the development of many pathological states. Nevertheless, the possibility that oxygen radical production was selected for during biological evolution in order to perform useful roles in relation to cellular metabolism is contemplated; previous data on this subject are briefly reviewed. The concept of an "oxygen radical cycle" is proposed as a useful theoretical model.
