低频交变磁场安全性的研究
Study on guidelines for low frequency time-varying magnetic field
【摘要】 目的:本文研究50Hz交变磁场对小鼠骨髓嗜多染红细胞(PCE)微核率和血象的影响。材料和方法:用50Hz交变磁场作用于小鼠,每天4小时,10天后检测小鼠骨髓嗜多染红细胞微核率和血液学指标。结果:表明经强度为10mT的低频交变磁场作用10天后的小鼠微核率与阴性对照组比较无显著性差异,而强度为15mT的实验组较阴性对照组微核率有明显增高(P<0.05),较阳性对照组仍有显著性差异(P<0.01),10mT和15mT的实验组的红细胞数均无明显改变,但白细胞数明显下降(P<0.05)。结论:提示当小鼠受到15mT交变磁场作用时,可使细胞微核率增加,可能会致突变。
【Abstract】 Aim: In this paper ,we studied the effect of the low-frequency magnetic on the micronuleus in PCE of the mouse bone marrow and blood. Materials and Methods: With 50 Hz time-varying magnetic field act on mice, 4 hours every day ,after 10 days ,the micronuclei rate of mouse bone marrow and blood were determined. Results: showed that there were not significant differences between 10mT, 50 Hz time-varying magnetic field and negative control group but there were significant differences between 15mT group and negative control group .and significant differences between 15mT group and position control group (P< 0.01). 10 mT and 15 mT groups, the amount of erythrocyte wasn’t significant varying, but the amount of leukocyte was significant decrease . Conclusion: The experiment demonstrated that the time-varying magnetic field probably cause sudden change of biological cell.
