The CB1 antagonist AM251 (3 mg/kg, i.p.) decreases capsaicin-evoked nocifensive behavior. This suppressive effect is genotype dependent, and the interaction between the effects of genotype and AM251 approached significance. Planned comparisons reveal that AM251 reduces nocifensive behaviors in fatty-acid amide hydrolase (FAAH) KO mice (p<0.01) but fails to alter nocifensive behavior in WT mice (p>0.2) relative to their respective vehicle controls. AM251 (3 mg/kg, i.p.) reduces the duration of heat hypersensitivity in FAAH KO (F1,9=21.43, p<0.01) but not WT mice (p>0.3). AM251 suppresses capsaicin-evoked heat hypersensitivity in a time-dependent manner in FAAH KO (F5,9=4.349, p<0.01) but not in WT mice (p>0.3). Post-hoc analysis reveals that FAAH KO mice receiving vehicle (i.p.) display heightened thermal hypersensitivity at 30 (p<0.05), 60 (p<0.05), and 90 (p<0.001) minutes post-capsaicin in comparison to FAAH KO animals receiving AM251). One-way ANOVA shows that AM251 (AM-251) injected into the rats significantly decreases both of the percentage of entries in the open arms and time spent in the open arms, compare to controls. The Tukey-Kramer test analysis reveals a significant reduction for the doses of 1 mg/kg (P<0.05) and 5 mg/kg (P<0.01) compare to control rats in the time spent in the open arms. Also, AM251 significantly decreases percentage of entries in the open arms for the doses of 1 and 5 mg/kg (P<0.05) |
