：利用大鼠胚胎中脑神经细胞作原代微团培养，培养物经不同强度的稳恒磁场作用，研究稳恒磁场对细胞生长和分化的影响，并利用图象分析细胞形态的变化。结果表明，各种强度的磁场能明显地抑制中脑神经细胞的分比．集落形成率明显减小，并显示强度效应关系。图象显示稳恒磁场可抑制中脑神经细胞分化，突起减少，认为稳恒磁场对细胞生长和分化有一定的抑制作用。
: Using rat embryonic mesencephalic neurons as primary micelles culture, the effect of steady magnetic field on cell growth and differentiation was studied by the effect of steady magnetic field with different intensities. The morphological changes of cells were analyzed by using images. The results show that the magnetic field of various intensities can significantly inhibit the ratio of midbrain nerve cells. Colony formation rate was significantly reduced, and showed the intensity effect relationship. The images show that the steady magnetic field can inhibit the differentiation of neural cells in the midbrain and reduce the protrusions, suggesting that the steady magnetic field can inhibit the growth and differentiation of cells.
