Protein bands of p-ERK, ERK, iNOS, and NF-κB p65 in the ipsilateral L4–5 spinal cord were detected by western blot analysis (a). Quantification of protein levels of p-ERK (b), ERK (c), iNOS (d), and NF-κB p65 (e). The decreased activation of ERK and NF-κB signals was observed in NCSC group. *p < 0.05, **p < 0.01, N = 3
