摘要: 目的 研究组胺作用于腹外侧视前区对大鼠睡眠-觉醒周期的影响。 方法 通过脑立体定位、 腹外侧视前区微量注射组胺, 脑电图仪记录及分析睡眠、 觉醒时相。结果 微量注射 50 μmol/L 组胺无明显影响, 而 100μmol/L组胺显著减少大鼠睡眠, 增加觉醒。 结论 组胺在腹外侧视前区对大鼠睡眠-觉醒周期发挥重要的调节作用, 具有明显的促觉醒作用。

Abstract: Objective To study the effect of histamine in rat ventrolateral preoptic area on sleep-wakeful?ness cycle. Methods Histamine was microinjected into ventrolateral preoptic area through stereotaxic technique,sleeping and waking time phases were recorded and analyzed by electroencephalograph.Results Microinjection of 50 μmol/L histamine had no significant effect,but 100 μmol/L histamine decreased sleeping time and increased waking time significantly. Conclusion Histamine is involved in regulation of sleep-waking cycle and promotes wakefulness significantly in the ventrolateral preoptic area.

Key words: histamine, ventrolateral preoptic area, sleep-wakefulness cycle
