NBP attenuates apoptosis after SCI. A. Immunofluorescence staining of cleaved caspase 3 in sections from the ventral horn of the spinal cord in the sham, SCI, and SCI+NBP groups at 7 d after SCI (magnification ×400). B, C. Protein expression and quantification analysis of cleaved caspase 3 in segments of injured spinal cord in the different groups at 7 d after SCI. Data represent Mean values ± SEM, **P < 0.01 versus the sham group, and #P < 0.05 versus the SCI group, n = 5 per group. D. TUNEL staining results in sections from the ventral horn of the spinal cord in the different groups at 7 d after SCI (magnification ×800). E. Quantification analysis of the number of TUNEL-positive cells. Data represent Mean values ± SEM, ***P < 0.001 versus the sham group, and #P < 0.01 versus the SCI group, n = 5 per group.
