To evaluate the effects of Zhumeria majdae essential oil (ZMEO) on morphine dependence and tolerance in mice.
ZMEO (10, 20, and 40 mg/kg) and clonidine (0.1 mg/kg) as the positive control were injected intraperitoneally (i.p.). The effect of ZMEO and clonidine on the dependence were evaluated by counting the number of jumps induced by naloxone (5 mg/kg) while the tolerance was evaluated by the tail-flick test.
ZMEO at the dose of 10 mg/kg during the development period led to a significant inhibition of morphine tolerance (P<0.01), while it led to reduced morphine dependence with the doses of 20 and 40 mg/kg. ZMEO at two dose levels of 20 and 40 mg/kg indicated significant antinociceptive activity (P>0.01), and significantly reduced the withdrawal signs (number of jumps) of mice (P>0.01).
ZMEO had significant effects on morphine tolerance and dependence. The linalool rich essential oil of Z. majdae plays a major role in the reduction of tolerance and dependence induced by morphine.
评价土木香挥发油（ZMEO）对小鼠吗啡依赖和耐受的影响。
ZMEO（10、20 和 40mg/kg）和可乐定（0.1mg/kg）作为阳性对照，腹腔注射。通过计算纳洛酮（5mg/kg）诱导的跳跃次数来评估 ZMEO 和可乐定对依赖的影响，通过尾巴闪烁试验来评估耐受。
在形成期，10mg/kg 的 ZMEO 显著抑制吗啡耐受（P<0.01），而 20 和 40mg/kg 的 ZMEO 导致吗啡依赖减少。20 和 40mg/kg 两个剂量水平的 ZMEO 均表现出明显的镇痛活性（P>0.01），并显著减少了小鼠的戒断症状（跳跃次数）（P>0.01）。
ZMEO 对吗啡耐受和依赖有显著影响。土木香富含的 linalool 精油在降低吗啡诱导的耐受和依赖方面起主要作用。
