Effect of methanolic extract of Mitragyna speciosa (MMS) (50–500 mg/kg, p.o.) on cage climbing behavior and cage climbing time induced by apomorphine (APO 5 mg/kg, i.p.) in mice. (A) Total time spent on the wall of the cage. (B) The cumulative climbing scores were measured for 30 min after apomorphine administration. (C) The climbing behavior was scored at 5 min interval after apomorphine treatment. Each point represents the mean ± SEM from the scores obtained from eight animals. Statistical significance: ###p < 0.001 compared with the saline control group; p < 0.05, ∗∗p < 0.01, ∗∗∗p < 0.001 compared with the vehicle control (VEH) group.
