经颅重复频率磁刺激(rTMS)对脑缺血大鼠血液流变学参数变化的影响

Objective The paper is to study the effect of repetitive transcranial magnetic stimulation（rTMS） on the hemorheology incelebral infarction rats. Methods Thirty male rats were randomly divided into three groups, namely: sham-operated group, cerebral ischemia-treated group, magnetic stimulation-treated group. The rats in stimulation-treated group were given rTMS 1h,3h,5h,9h,11h,18h after cerebral ischemia-treated. All of rats were get blood from aorta abdominalis after twenty hours, This paper's purpose is to discover the effect of repetitive transcranial magnetic stimulation to hemorheology of the rat between different groups. Result Compare to the rats in cerebral ischemia-treated group, rTMS can obviously decrease the blood viscosity in of the cut, blood viscosity low-cut, and erythrocyte sedimentation, increase the survival rate in magnetic stimulation-treated group. Conclusion rTMS play an important part in protect brain from the damage caused by cerebral ischemia. The reason may be related to improve the change of hemorheology after cerebral ischemia.
