Abstract:
Objective To investigate the effects of transcranial magnetic stimulation(TMS)on the recovery of neurological function and the expression of neurofilament protein(NFP)-200 in rats with cerebral infarction.Methods The string-fastening method was used to establish focal ischemia-reperfusion models in 60 Sprague-Dawley rats and the rats were divided into the TMS group and the sham TMS group(composed of 30 rats each).Then each group were divided into the treated 1 d,3 d,7 d,14 d and 21 d subgroups(composed of 6 rats each).TMS group rats were administered with 2 sessions of TMS(200 pulses total)daily,keeping on corresponding days in different groups.The recovery of neurological function and the optical density of NFP-200 by immunohistochemistry in the infarct peripheral zone in two groups were detected after therapy.Results At the 14 d and 21 d after treatment,neurological deficit scores of TMS group(2.67?0.82,1.50?0.55) were significantly lower than those of the sham TMS group(3.67?0.52,3.17?0.75)(P
