The involvement of the adrenergic system in MEMC-induced antinociception against acetic acid-induced abdominal writhing test in mice. Each column represents the mean ± S.E.M. of six mice. Control (C: 10% DMSO, p.o.), prazosin (PRA: 0.15 mg/kg, i.p.), Phenylphrine (PHE: 10 mg/kg, i.p.), Yohimbine (YOH: 0.15 mg/kg, i.p.), Clonidine (CLO: 0.15 mg/kg, i.p.) and MEMC (500 mg/kg, p.o.). ^ap < 0.05 significantly different from control group; ^#p < 0.05 significantly different when compared between respected treatment groups.
