| 本文研究了低频交变磁场对细胞作用的理论机理和实验结果。交变磁场和交变磁场感应的电场对运动离子产生电场
力, 加速离子的运行。基于该理论分析, 设计了一系列的实验来验证假定的理论, 实验采用两种肿瘤细胞系( HL- 60 and SK- Hep
- 1) 。将肿瘤细胞暴露于50Hz, 20mT 连续正弦磁场4 天, 每24 小时检测上清液Na+ 和K+ 浓度。结果发现, 照射组和对照组的
Na+ 和K+ 浓度有显著变化, 实验结果和理论分析相符。 |
| 英文摘要: |
| In this paper, a theoretical mechanism and experiments for the effects of low frequency oscillating magnetic field on cells were
investigated and analysed. Magnetic field varying with time and its inducing electric field produce the force on the moving ions and accelerate the
ions. On the basis of the theoretical analysis, a series of experiments were designed to test the supposed theory. Two human cancer cell lines ( HL
- 60 and SK- Hep- 1) were used in our experiment. The cancer cells were exposed to a continuous sinusoidal 50Hz, 20mT magnetic field for
4 days. The results demonstrate the significant changes of Na+ and K+ ion concentrations in cell supernatant compared with the control group.
These results of experiments appear to be consistent with the theoretical analysis. |
