摘要
目的 :探索睡眠剥夺的脑机制。方法 :该研究采用小平台水环境法建立大鼠睡眠剥夺模型 ,用fos蛋白免疫组化的方法测量脑中fos蛋白的表达 ,分组为白天睡眠剥夺 12h组、夜晚睡眠剥夺 12小时组、大平台对照组和正常单独饲养组 ,每组 4只。结果 :睡眠剥夺使fos蛋白在皮层的广泛区域表达 ,脑干中同异相睡眠有关的区域有较高表达 ,同夜晚睡眠剥夺 12小时相比 ,白天睡眠剥夺 12小时在视交叉上核同生物节律有关的区域表达。结论
Objective: To investigate the brain mechanisms of sleep deprivation. Methods: Sprague-Dawley rats were sleep deprived by housing them on the small platforms over water. Controls were housed in the normal cage(CC) or on the large platforms over water(TC). The effects of SD on the expression of c-fos protein by immunocytochemistry were investigated. The duration of SD was about 12 hours. They were divided into two groups: early SD group (from 7:00 am) and the late SD group (from 19:00 pm). Results: SD resulted in different expression of c-fos protein at different fields of the brain. The main fields of brain stem were all connected with paradoxical sleep. Compared with the late SD, the early SD group showed higher fos protein expression on suprachiasmatic.Conclusion: The disruption of regular circadian rhythm may affect c-fos protein expression.
