英《泰晤士报》1982年8月18日报道:人体似乎有利用其体内自由基的能力,使其本身具有有利条件来对抗肿瘤细胞. 加拿大一个研究组的生物学家们发现,一种称为天然杀伤细胞的白细胞在接触到癌细胞的数秒钟内,就可释放出一种过氧化物自由基.生物学家认为,过氧化物的释放可触发一系列反应,最后导致癌细胞死亡。在自由基与其他分子起反应前,通常生存的时间很短.生物可 The British “The Times” reported on August 18th, 1982: The human body seems to have the ability to use its free radicals in the body and it has its own favorable conditions to fight tumor cells. A biologist from a Canadian research group has discovered that White blood cells of natural killer cells release a peroxide radical within seconds of exposure to cancer cells. Biologists believe that the release of peroxide triggers a series of reactions that eventually lead to the death of cancer cells. Before the reaction of free radicals with other molecules, the survival time is usually very short.
