The involvement of the serotonergic 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.), Pindolol (1 mg/kg, i.p.), and MEMC (500 mg/kg, p.o.). ^ap < 0.001 significantly different from control group; ^bp < 0.001 significantly different when compared pindolol-treated group; ^cp < 0.01 when compared to MEMC-treated group.
