手机电磁辐射对小鼠自由基影响的研究

Effects of Mobil Phones' Electromagnetic Radiaton On the Free Radicals in Rats

目的 :研究经手机电磁辐射后的小鼠血清中SOD、MDA含量的变化 ,推断手机电磁辐射可能对人体造成的早期损害。方法 :应用分光光度比色法检测手机辐射后血清SOD、MDA含量 ,并与对照组进行统计学比较 ,同时电镜下观察大脑皮层、海马、小脑超微结构的变化。结果 :实验组小鼠血清SOD低于对照组 ,有显著性差异 (P <0 .0 5 ) ,而实验组MDA含量明显高于对照组 (P <0 .0 1) ;电镜下 ,实验组大脑皮层、海马、小脑超微结构与对照组相比较没有明显改变。结论 :手机辐射使小鼠体内自由基生成增多 ,对机体细胞造成早期损伤。

Objective: To find out early damage effects to human of Mobil phones' electromagnetic radiation(EMR)by detecting the changes of superoxide dismutase (SOD) and malondialdehyde (MDA) in serum of rats after radiation of Mobil phones' EMR.Method: The contents of SOD and MDA in serum were recorded with spectrophotometry. And the change of ultrastructure of cerebral cortex, hippocampus and cerebellum were observed by electro microscope. Results: Compared to normal controls, the contents of SOD in rats′ serum were reduced significantly(P<0.05). And the contents of MDA in rats′ serum were increased significantly (P<0.01) after treatment of Mobil phones' EMR. Another way, the ultrastructure of cerebral cortex, hippocampus and cerebellum did not change significantly.Conclusion: The result of experiment showed that the mobil phones' EMR can increase the formation of free radicals and produce early damage to body.
