Fig. 1. In chronic constriction injury (CCI) rats, the paw withdrawal thresholds (PWTs) and paw withdrawal latencies (PWLs) in the ipsilateral were decreased from day 3 after modeling and reached a stable level from day 7 (A, C). The PWTs and PWLs in the contralateral side in each group had no significant changes in time points (B, D). The error bar means mean ± standard deviation. aP < 0.05 vs. sham; Two-way ANOVA; n = 11 rats in each group.
