大多数抗癌药如阿霉素、争光霉素等在机体内通过产生自由基而发挥抗癌作用,与此同时,这种自由基也损害健康的脏器,并且产生的各种有害作用还能导致癌症。患癌机体因其主要脏器中的自由基清除剂超氧化物歧化酶(SOD)逐渐减少,导致机体内产生的自由基(内因性)不能被消除而过剩,使健康脏器受到损害。如果给这样的患癌机体使用产生自由基(外因性)的抗癌药,将使内因性自由基诱发的损害越来越加重。因此,如果把自由基清除剂和这类抗癌药合并用
Most anticancer drugs such as doxorubicin, bleomycin, etc. exert anticancer effects in the body by generating free radicals, and at the same time, such free radicals also damage healthy organs, and various harmful effects also occur Can cause cancer. Cancerous body due to its main organs in the free radical scavenger superoxide dismutase (SOD) decreased, leading to the body’s free radicals (internal) can not be eliminated and excess, so that damage to healthy organs. The use of anti-cancer drugs that produce free radicals (extrinsic) in such cancer-bearing organisms will aggravate the damage induced by intrinsic free radicals. Therefore, if the free radical scavenger and such anticancer drugs combined
