Abstract:
Objective To observe the effect of static magnetic field (SMF) on the spinal cord neurons in Vitro.
Methods Spinal cord neurons were treated with different intension of static magnetic field and the growth of the cells was analyzed by plotting cell growth curve and MTT assay. The growth condition of cell was observed with phase-contract microscope, and intracelluer dehydrase activity was detected.
Results 1-10 mT of static magnetic field had no inhibitory effect on the spinal cordneurons. The effect developed when the intension was up to 50-200 mT, and the inhibitory effect of magnetic field became more significant with the increase of the intension.
Conclusion Hint to certain strength of static magnetic field had inhibitory effect on spinal cord neurons in vitro, there was dose-effect relationship intension.
