目的:探讨胚胎期暴露手机辐射对仔鼠脑组织NO和SOD的影响。方法:将22只孕鼠分为3组,2个实验组母鼠妊娠全程暴露于手机辐射,对照组母鼠未暴露于手机辐射下。分娩8周后应用酶免疫标记技术测定暴露组和对照组仔鼠脑组织NO含量和SOD活性。结果:胚胎期暴露手机辐射仔鼠脑组织中NO含量高于对照组(P<0.05),SOD活性低于对照组(P<0.05)。时分多址组与码分多址组间NO含量及SOD活性比较,均无统计学差异(P>0.05)结论:胚胎期暴露手机辐射可能引起仔鼠脑组织中NO浓度上升,SOD活性降低。
Objective: To investigate the effect of embryonic exposure to cellphone radiation on NO and SOD in the brains of the offspring. Methods: Twenty-two pregnant rats were divided into three groups. The mothers in the two experimental groups were exposed to cell phone radiation during pregnancy, while the control rats were not exposed to the cell phone radiation. Eight weeks after delivery, enzyme-linked immunosorbent assay (ELISA) was used to determine NO content and SOD activity in the brains of exposed and control groups. Results: The content of NO in the brain tissue of exposed cell phone exposed by embryo was higher than that of the control group (P <0.05) and the activity of SOD was lower than that of the control group (P <0.05). There was no significant difference in NO content and SOD activity between time division multiple access group and code division multiple access group (P> 0.05). Conclusion: Exposed cell phone radiation in embryonic stage may increase NO concentration in brain tissue and decrease SOD activity.
