Effects of the different frequency EA treatments on COX-2 expression in the brains of the CPSP rats. (a) Representative photomicrographs of immunohistochemical staining of COX-2 expression in the brains of the CPSP rats that had been treated with or without EA on the 5th day after the operation. (b) Determination of COX-2 expression in the brains of the CPSP rats using a multispectral analysis (ipsilateral brain section). (c) Representative Western blots of COX-2 expression in the ipsilateral neocortex and hippocampus of the CPSP rats. (d) Western blot determination of (c). and denote , 0.001 versus the control; and denote , 0.001 versus the model ( in each group; one-way analysis of variance, followed by the Newman-Keuls post hoc test).
