Quantitative comparison of residual myelin areas in all groups at the injured site and at 3 and 5 mm rostral (+) and caudal (-) from the epicenter after contusive SCI. (A) Statistically analyzed spinal tissue. (B) +5 mm, (C) +3 mm, (D) 0 mm, (E) -3 mm and (F) -5 mm. The results are expressed as the mean ± SD (n=4). Data were analyzed with one-way ANOVA followed by Tukey's post hoc test. *P<0.05 and **P<0.01 vs. MP group. MP, methylprednisolone; SCI, spinal cord injury; TT, treadmill training; LFB, Luxol fast blue.
