探讨大麻二酚(CBD)对咖啡因(CAF)诱导的小鼠睡眠抑制行为的拮抗作用。
采用戊巴比妥钠协同催眠实验,观察不同剂量CAF对正常小鼠睡眠时间的影响,并评价CBD对CAF所致睡眠抑制的调节作用;使用自发活动视频分析系统,评估CAF及CBD对小鼠自主活动行为的影响;采用小鼠腺苷检测试剂盒(ELISA)测定血清腺苷水平,并利用高效液相色谱法(HPLC)检测下丘脑的谷氨酸含量。
CAF(40 mg/kg)显著延长小鼠睡眠潜伏期(P<0.001)并缩短睡眠持续时间(P<0.01);CBD(10 mg/kg)则可显著缩短睡眠潜伏期(P<0.001),延长睡眠持续时间(P<0.001)。CAF(10 mg/kg)组小鼠活动总路程增加(P<0.05)、平均速度加快(P<0.05)、中央区域停留时间延长(P<0.05);CBD(10 mg/kg)干预后,活动总路程减少(P<0.01)、平均速度减慢(P<0.01)、中央区域停留时间缩短(P<0.001)。CAF(40 mg/kg)组小鼠下丘脑谷氨酸含量升高(P<0.001),血清腺苷含量亦显著升高(P<0.01);CBD(10 mg/kg)处理可显著降低谷氨酸(P<0.001)与腺苷(P<0.001)水平。
CAF可干扰正常小鼠睡眠,并引起谷氨酸与腺苷水平异常;CBD对于CAF诱导的睡眠抑制具有一定的拮抗作用。

To investigate whether cannabidiol (CBD) has an antagonistic effect on caffeine (CAF)-induced sleep inhibition in mice.
A pentobarbital sodium synergistic hypnosis test was used to observe the effects of different doses of CAF on sleep duration in normal mice and to evaluate the regulatory effect of CBD on CAF-induced sleep inhibition. A spontaneous activity video analysis system was employed to assess the effects of CAF and CBD on autonomous locomotor behavior in mice. Serum adenosine levels were measured using a mouse adenosine detection kit (Enzyme-Linked Immunosorbent Assay, ELISA), and hypothalamic glutamate content was detected by High Performance Liquid Chromatography (HPLC).
CAF (40 mg/kg) significantly prolonged sleep latency (P<0.001) and shortened sleep duration (P<0.01) in mice, whereas CBD (10 mg/kg) significantly shortened sleep latency (P<0.001) and prolonged sleep duration (P<0.001). In the CAF (10 mg/kg) group, the total distance traveled by mice increased (P<0.05), the average speed accelerated (P<0.05), and the time spent in the central area prolonged (P<0.05). After CBD (10 mg/kg) intervention, the total distance traveled decreased (P<0.01), the average speed slowed (P<0.01), and the time spent in the central area shortened (P<0.001). The hypothalamic glutamate content increased (P<0.001) and serum adenosine levels also significantly rose (P<0.01) in the CAF (40 mg/kg) group. CBD (10 mg/kg) treatment significantly reduced both glutamate (P<0.001) and adenosine (P<0.001) levels.
CAF disrupts normal sleep in mice and induces abnormalities in glutamate and adenosine levels; CBD counteracts these CAF-induced sleep disturbances and normalizes the neurochemical alterations.
