目的 探讨低功率微波长时间连续照射 ,对大鼠精子畸形和骨髓嗜多染红细胞微核形成的影响 ,以进一步研究低功率微波的遗传损害效应。方法 动物随机分成 3组 ,设对照组进行虚拟暴露 ,试验组经 180 0MHz(连续波 )电磁场中功率密度分别为 0 5mW cm2 (实验Ⅰ组 )和 1 0mW cm2 (实验Ⅱ组 )照射 ;每天照射 12h ,连续 2 1d后 ,观察大鼠的精子畸形和检测骨髓嗜多染红细胞微核形成情况。结果 大鼠经 180 0MHz(连续波 )电磁场中照射 2 1d后 (功率密度分别为0 5mW cm2 和 1 0mW cm2 ) ,其精子畸形率和骨髓多染红细胞微核率与对照组相比无显著性差异 (P >0 0 5 )。结论 大鼠经模拟手机辐射强度的低功率微波照射后未能引起明显的遗传损害。

Objective To investigate the genetic effect of low power microwave radiation on the anomaly of sperm and micronucleus(MN) formation in the marrow polychromatic erythrocyte (PCE) in rat. Methods Rats were randomly divided into three groups, namely control, experimental group Ⅰ and experimental group Ⅱ. Abnormal sperms and MN formation in marrow PCE were observed and detected after exposure to 1 800 MHz (Continuous wave, CW) microwave radiation for 21 days (12 h/d) with the average power density of 0 mW/cm 2 (control), 0 5 mW/cm 2 (group Ⅰ) and 1 0 mW/cm 2 (group Ⅱ). Results No significant difference in the rate of sperm abnormality and MN formation in marrow PCE was found between the experimental groups and the control. Conclusion No obvious genetic damage caused by low power microwave radiation to the sperm anomaly and MN formation in marrow PCE of rats is found.
