Figure 2. DPN protects spinal cord tissue against SCI-induced apoptosis. Treatment of DPN significantly reduces activated caspase-3 level after 24 h following SCI induction. The results are expressed as mean ± SEM of 3 independent experiments. * p < 0.05, ** p < 0.01, *** p < 0.001 compared to normal control; # p < 0.05, ## p < 0.01 compared to SCI group.
