【摘要】 机体在新陈代谢过程中 ,不断产生自由基 ,自由基对细胞结构损伤较大 ,机体内存在清除自由基的酶类 ,正常条件下 ,自由基的产生和清除是动态平衡的 .过氧化氢酶是重要抗自由基酶类之一[1 ] .试验企图探讨DNA对过氧化氢酶活性影响 ,从而探索核酸对抗自由基和抗衰老的作用更多还原

【Abstract】 The activity change of catalase,an important anti-oxidative enzyme,in the blood of mice after supplementation of specially purified deoxyribonucleic acid(SPDNA) was studied.The decrease of catalase activity with nouse age was prohibited significantly following SPDNA supplementation,which implies an anti-oxygen radical activity of our SPDNA in vivo.更多还原
