Fig. 5. Botulinum toxin type A (BTX-A) injection reversed the decrease of paw withdrawal thresholds (PWTs) in the ipsilateral hind paw of chronic constriction injury (CCI) rats from day 10 after modeling (A). However, the PWTs in the contralateral side had no significant changes in each group (B). The error bar means mean ± standard deviation. aP < 0.05 vs. CCI + normal saline (NS) group, Two-way ANOVA, n = 6 in each group.
