Fig. 2From: Small-conductance calcium-activated potassium (SK) channels in the amygdala mediate pain-inhibiting effects of clinically available riluzole in a rat model of arthritis painLack of effect of systemically applied riluzole on spinal withdrawal thresholds. Induction of arthritis significantly reduced hindlimb withdrawal thresholds measured by mechanical compression of the knee joint. Systemic application of vehicle (HBC, 30 %, i.p.; n = 11 rats) or riluzole (8 mg/kg, i.p.; n = 7 rats) had no effect compared to predrug values. Bar histograms show mean ± SEM. n.s. non-significant; ***P < 0.001; repeated measures one-way ANOVA with Bonferroni posttestsBack to article page
