It was found in the present study that low frequency (2Hz) electroacupuncture (EA) stimulation caused a decrease of the content of substance P immunoreactivity (SP-ir), whereas medium-(15Hz), high-(100Hz) and dense-disperse (D-D)- (2/15Hz) frequencies EA stimulation induced an increase of the content of SP-ir in the rat spinal fluid. EA analgesia induced by… (More)
