c-fos expression in the cervical spinal cord. (A) Representative photomicrographs and (B) quantitative results of c-fos expression in the spinal cord. The c-fos-positive neurons were observed under a light microscope at high-power field (HPF) magnification, and the average number of c-fos-positive neurons was counted single-blind using the imaging software. **P < 0.01 compared to control group. # P < 0.05 compared to compound 40/80 group).
