Gabapentin administration promoted recovery of injured spinal cord following decompression in CSM rats. A The pathological changes of anterior horn in spinal cord were observed by HE (scale = 500 μm, 100 μm). B The changes of axons in the anterior horn of spinal cord were measured by LFB staining (scale = 50 μm). C The levels of caspase-3 (red arrows) in the anterior horn of spinal cord were analyzed by immunohistochemistry (scale = 100 μm). The positive expression of caspase-3 was analyzed by Image J software. Compared with the sham group, ^**P < 0.01; compared with the decompression + vehicle group, ^##P < 0.01
