心理应激对大白鼠自由基损伤的影响

本研究将动物分为实验模型５天、１０天、２０天组及对照组，并检测各组动物上述组中的ＬＰＯ、ＳＯＤ、ＣＡＤ水平进行了分析；研究因噪音诱发的心理应激反应时大白鼠脑、肝、肺、心、肾组织自由基损伤情况及防御酶的活性变化；结果发现：在心理应激反应条件下，动物各组织的因自由基反应而使ＬＰＯ含量升高、防御酶ＳＯＤ、ＣＡＤ活性下降，表明：１．心理应激可以诱发动物体内产生大量的自由基，并对脑、肝、肺、心、肾组织产生影

Effects of Psychological Stress on Rats' Free Radicals

The present research studied the damage of the free radicals of rats' brain, liver, heart, kidney and the change of anti-free radical enzymes when the psychological stress caused by noise occurred In the experiments, there were three experimental groups (5-day group, 10-day group, 20-day group) and control groups The LPO, SOD and CAD of the rats' organs mentioned above were analysed The results were as follows: 1)Psychological stress could make the animal produce more free radical ,and have effects on the brain, liver, heart, kidney tissues; 2) During short term stress, the tissues mentioned above could get rid of free radicals through SOD or CAT If stress reaction was prolonged, the effect of anti-free radical enzymes decreased
