Abstract:OBJECTIVE: Dependence and tolerance are major restricting factors in the clinical use of opioid analgesics. In the present study, the effects of thymoquinone, the major constituent of Nigella sativa seeds, on morphine dependence and tolerance were investigated in mice.
MATERIALS AND METHODS: Male adult NMRI mice were made tolerant and dependent by repeated injections of morphine (50, 50,和75毫克/千克,下午9点d分别下午5点)在为期3天的管理时间表中。热板测试用于评估吗啡的镇痛作用的耐受性。纳洛酮(2 mg/kg,i.p.)被注入沉淀戒断综合征,以评估吗啡依赖性。为了评估胸喹酮对耐受性和对吗啡依赖性的影响,在小鼠中施用了不同的单一或重复剂量的胸喹酮。 rotarod用于评估运动配位。
结果: 单剂量或重复剂量的胸腺醌(20和40 mg/kg,i.p.,i.p.)的给药显着减少了吗啡依赖性动物的跳跃数量。重复施用胸腺合酮(20和40 mg/kg,持续3天),并单次注射胸醌(第四天40 mg/kg)减弱了对吗啡的止痛作用的耐受性。胸喹酮剂量(10、20和40 mg/kg)均未产生任何抗伤害感受的作用我自己的。高剂量的胸腺喹酮(40 mg/kg)。
结论: 基于这些结果,可以得出结论,胸喹酮可以预见到耐受性和
