摘要
目的:研究松针提取液对小鼠血细胞DNA损伤率的影响。方法:40只昆明种小鼠随机分成安静组和训练组,两组又分设对照组和松针提取液组。服药组小鼠短期连续服用松针提取液8g/kg.d,20天后小鼠力竭游泳后测定超氧化物歧化酶(SOD)、血尿素氮(BUN)、血红蛋白(Hb)、血细胞DNA损伤率等指标及力竭游泳时间。结果:服药组小鼠短期连续服用松针提取液后,小鼠血清SOD活性显著性升高,小鼠体内蛋白质供能比例降低,Hb含量明显提高,小鼠血细胞DNA损伤率明显降低。结论:说明松针提取液可以降低血细胞DNA损伤率。
Objective：To study effect of the extract of pine needles upon the rate of injure of DNA. Methods ： 40 mice of Kun Ming stain was divided into two groups：comparative group and exercise group. The two groups was divided into another two groups： comparative group and group fed by the extract of pine needles 8g/kg-d. the Supersoxide Dismutase（SOD） , the Blood Urea Nitrogen（BUN）, the Hemoglobin（Fib）, injure of DNA and swimming time were measured. Resu/ts： the Supersoxide Dismutase （SOD） improved renmrldy, the rate of protein energy reduced, the Hemoglobin（Hb） improved, the rate of injure of DNA reduced remarkly. Conclusion ： the extract of pineneedles has the function to reduce the rate of injure of DNA.
