【摘要】 目的为了研究磁场对自由基代谢的影响，测定了经磁场处理后小白鼠血液中的谷胱甘肽过氧化物酶ＧＳＨ—ＰＸ的活性。方法Ｓｗｉｓ小鼠随机分成实验组Ａ、Ｂ及对照组，实验组Ａ、Ｂ小鼠分别用强度为８０ｍＴ和４０ｍＴ的磁场照射，每日３０分钟，１５天后用分光光度法测定小鼠血液中的ＧＳＨ—ＰＸ的活性。结果实验组Ａ小鼠血液中的ＧＳＨ—ＰＸ活性显著高于对照组（Ｐ＜０．０５）；而实验组Ｂ小鼠血液的ＧＳＰ—ＰＸ活性与对照组比较亦有提高，但无显著差异。结论经一定强度、一定时间的磁场处理后的小鼠血液清除自由基能力明显提高。更多还原

【Abstract】 Objective We measured the activities blood GSP—PX in the mice treated by the static magnetic fields for exploring the effect of magnetic fields on the metabolism of free radical. Methods The Swiss mice were divided randomly into experimental group A,group B and control group.The mice of experimental group A and group B were treated by the static magnetic fields with the intensity of 80mT and 40mT respectively for 30 minutes a day.After 15 days we measured the activities of blood GSH-PX in the mice by using spectropholometric method. Results The experimental results are that the GSH-PX activities of experimental group A are obviously higher than those of the control group (P<0.05).Although the GSH-PX activities of group B are higher than those of the control one too,but they have no apparent difference. Conclusions Above mentioned results show that after the mice have been treated by the static magnetic fields with a certain intensity for a period of time,the abilities of the mice to remove freely radical were obviously enhanced.更多还原
