A Image of spinal tissue specimen. B H&E staining of spinal cord tissues in different groups; scale bar lengths are 1000 μm. C LFB staining of spinal cord tissue in different groups, Left: scale bars = 500 μm; right: scale bars = 50 μm. D Semiquantitative analysis of the cystic cavity area in different groups, *P < 0.05, error bars represent standard deviation for n = 3. E Semiquantitative analysis of the LFB staining area in different groups, *P < 0.05, error bars represent standard deviation for n = 3
