I-V relationships of K+ currents in capsaicin-sensitive bladder afferent neurons from mice. K+ currents evoked by depolarizing voltage pulses from −80 to +30 mV. Values present means ± SD. *p < 0.05, significant difference between SI and SCI groups or SI and SCI + p38 MAPK inhibitor groups, one-way ANOVA, followed by post hoc analysis with the Bonferroni’s method. #p < 0.05, significant difference between SCI and SCI + p38 MAPK inhibitor groups, one-way ANOVA, followed by post hoc analysis with the Bonferroni’s method. SI; spinal intact group, SCI; spinal cord injury group, SCI + p38 MAPK group; spinal cord injury treated with p38 MAPK inhibitor (0.51 μg/h, i.t.) for two weeks. The number of neurons/mice per group is 24/9; SI, 24/9; SCI and 18/7; SCI + p38 MAPK inhibitor, respectively.
