Comparison of Effects of 5 and 20 Hz Magnetic Field on Cerebral Ischemia in Rats
Abstract：Objective To compare the effects of 5 Hz and 20 Hz magnetic field on cerebral ishemia in rats. Method After cerebral ischemia was produced by ligation of the left general carotid artery,rats were stimulated by magnetic fields of 5 Hz and 20 Hz respectively and pathological changes in neurocytes were observed. Result (1) Different pathological changes were observed in different cells;(2)The extent of damage of pyramidal cells was milder in 5 Hz magnetic field groups than those in the control group ,and the effect was not remarkable in the 20 Hz group;(3)The effect on astroglia was worse in 5 Hz group than that in control and 20 Hz group. Conclusion Magnetic field stimulation influences cerebral ischemic reaction with frequency-dependency.
