Effects of QCN on oxidative stress of the BPA rats at week 2 post-avulsion. A Representative images of nNOS staining cells in the ipsilateral C6–7 ventral spinal segments at 2 weeks post-avulsion injury. B Quantification of nNOS staining cells of each group. (Scale bar 200 μm. n = 6). C The protein levels of Nrf2 and HO-1 as determined by western blot. Quantification of D Nrf2 and E HO-1 protein in the ventral horn of the C6–7 spinal segments. Data are expressed as the mean ± SEM (n = 3). ^### p < 0.001 vs the sham group; *p < 0.05, **p < 0.01, and ***p < 0.001 vs the vehicle group
