[Effect of extremely low frequency (correction of frenquency) magnetic field on brain ischemic reaction in rats].
The effect of extremely low frequency magnetic field (ELMF, 15 Hz, 18 mT) on ischemic brain produced by ligation of general carotid artery in left side was studied in rats. The results showed that the degree of brain blood vessel dilation was higher in magnetic field group than that in control group at the 1st, 3rd and 6th hour after ligation and the extent of damage of neurocyte was apparently lighter in magnetic field group than that in control group at the 3rd and 6th hour after ischemia. It indicates that ELMF stimulation improves the brain blood circulation after brain ischemia and alleviates the brain ischemic reaction.
