Effects of Dezocine on μ agonist morphine-induced antinociception. Mice were injected with morphine with or without Dezocine. After 15 min, the antinociception was measured in the abdominal constriction test. Data are presented as mean ± SEM from at least 10 mice. *p < 0.05 in comparison with 0.3 mg/kg morphine, #p < 0.05 in comparison with 0.4 mg/kg morphine.
