为探讨不同量的乙醇对SOD活力和MDA含量的影响 ,分别按家兔每公斤体重累加 0 .2 g、0 .5g、1.0 g的乙醇给予静注 ,然后分别测定不同量的乙醇作用下机体内的SOD活力和MDA含量 ,并进行比较分析。结果显示 :0 .2g、0 .5 g/kg体重乙醇时SOD活力增强 ,MDA含量降低 ,1.0 g/kg体重乙醇时SOD活力降低 ,MDA含量增加。认为机体对乙醇反应与用量不同有关 ,量少可提高SOD的活力和降低MDA含量 ,而量多则相反。进一步证实“饮酒少量有益 ,过量有害”这一提法 To investigate the effect of different amounts of ethanol on the activity of SOD and the content of MDA, 0.2 g, 0.5 g and 1.0 g of ethanol were added per kg of body weight of rabbit to give intravenous injection. Then, Within the SOD activity and MDA content, and comparative analysis. The results showed that SOD activity increased and MDA content decreased at 0. 2g and 0. 5 g / kg body weight ethanol, SOD activity decreased and MDA content increased at 1.0 g / kg body weight ethanol. That the body’s response to ethanol and the amount of different, less can increase the vitality of SOD and reduce MDA content, while the amount of the contrary. Further confirmed that “drinking a small amount of useful, excessive harmful” this reference
