ABSTRACT
Objective To investigate the protective effects of low-frequency pulsed electromagnetic field (LFPMF) on neuron following cerebral ischemia-reperfusion injury in rats.Methods 24 adult male Sprague-Dawley rats were randomly divided into irradiation group (n=12) and control group (n=12). The global cerebral ischemia-reperfusion models of rats were produced by modified Pulsineli method. Rats in irradiation group were exposed to 20 mT intensity LFPMF of 10 Hz for 45 minutes per day for 4 days. The electroencephalogram (EEG) was recorded by powerlab system. Nissl staining was used to perform quantitative analysis of neuron number and immunohistochemistry staining provided the information of the distribution of positive cells to caspase-3.Results Compared with the control group, the amplitude of EEG was significantly higher in irradiation group [(10.27?1.12)?V versus (8.95?1.04)?V] (P
