The effects of Schisandra Fruit on the sleep of freely moving rats

目的:观察五味子水煎液对自由活动大鼠睡眠时相的影响。方法:采用大鼠皮层脑电图描记技术,观察五味子水煎液对大鼠总睡眠时间及各睡眠时相的影响。结果:五味子水煎液能延长正常大鼠总睡眠时间(total sleep time,TST),在睡眠时相上表现为明显延长大鼠慢波睡眠Ⅱ期(slow wave sleep 2,SWS2),对慢波睡眠Ⅰ期(slow wave sleep 1,SWS1)和快波睡眠(fast wave sleep,FWS)无影响。结论:五味子水煎液具有改善睡眠的作用。
