Electroacupuncture Treatment Alleviates Central Poststroke Pain by Inhibiting Brain Neuronal Apoptosis and Aberrant Astrocyte Activation

Figure 1

Effects of the different frequency EA treatments on pain-related behavioral responses and neuropathological changes in the brains of the CPSP rats. Changes in the thermal (a), cold (b), and mechanical (c) hyperalgesia in the contralateral paw of CPSP rats that had been treated with or without EA at different frequencies. (d) Representative photomicrographs of Nissl staining in equivalent coronal sections of the brains of the CPSP rats on the 5th day after the operation. denotes p < 0.05 versus the control; denotes p < 0.01 versus the model ( in each group; one-way analysis of variance, followed by the Newman-Keuls post hoc test).
