Figure 4.
The effect of intraplantar administration of K+ channel blockers on the peripheral antinociceptive effect of FKB against carrageenan-induced hyperalgesia test in rats. Tetraethylammonium (TEA; 200 µg/paw), glibenclamide (GLI; 200 µg/paw), charybdotoxin (ChTX; 3 µg/paw) and apamin (APA; 3 µg/paw) were administered 15 min before FKB (500 µg/paw). Each column represents the mean ± S.E.M. (n = 6). *** p < 0.001 when compared with the control (C) group; ## p < 0.01, ### p < 0.001 when compared with the FKB group (one-way ANOVA followed by Dunnett’s post hoc).
