In CFA experiments symbols indicate significant differences from the pre-CFA treatment (***P < 0.01) and post-CFA treatment PWT values (##P < 0.01, ###P < 0.001), respectively. One-way ANOVA followed by Neuman–Keuls post-hoc test, n = 6–12/group. In Seltzer experiments symbols indicate significant differences from the pre-CFA treatment (***P < 0.01) and from the postoperative values of saline (SAL) or vehicle (VEH) treated animals (#P < 0.05, ##P < 0.01, ###P < 0.001). One-way ANOVA followed by Neuman–Keuls post-hoc test, n = 6–12/group. In hot plate tests asterisks indicate significant analgesic effect, compared to the pre-treatment values, *P < 0.05, **P < 0.01, paired t-test. n.d. = not determined.
