鲤鱼精巢ＤＮＡ对组织匀浆自发的或由Ｆｅ２~(＋)－Ｃｙｓｔｅｉｎｅ体系激发的脂质过氧化作用均有显著的抑制作用，在０．１６～１００μｇ／ｍＬ浓度范围内有明显的剂量依赖关系；小鼠ｉｍ ＤＮＡ １５ ｄ，其脑、心、肝中雨二醛生成量明显减少；小鼠ｉｇ ＤＮＡ ４５ ｄ，其脑和肝脏中的脂褐素含量明显低于空白对照组。
The testicular spermatogonia DNA had significant inhibitory effect on the lipid peroxidation spontaneously induced by the tissue homogenate or stimulated by the Fe2~(+)-Cysteine system, and there was a significant dose-dependent relationship in the concentration range of 0.16 to 100 μg/mL. Mice im DNA 15 d, the brain, heart, liver diarrhea production decreased significantly; mice ig DNA 45 d, the brain and liver lipofuscin content was significantly lower than the blank control group.
