摘要
目的:研究完全睡眠剥夺对大鼠海马和皮质IL-1βmRNA表达的影响。方法:将大鼠放入1转/分钟转笼中,制作经历不同持续时间的完全睡眠剥夺(TSD)模型。30只大鼠随机分为5小组:对照组(正常对照CC组,环境对照 TC组)和睡眠剥夺组[TSD6h组,TSD1d组,TSD3d组(n=6只)]。采用RT-PCR方法检测大鼠海马和皮质IL- 1βmRNA表达。结果:大鼠海马区,TSD6h组和TSD1d组IL-1βmRNA的表达明显高于对照组,TSD3d组更为明显;皮质区TSD3d组表达也明显增多。结论:完全睡眠剥夺大鼠海马和皮质IL-1βmRNA表达增高,且随时间的延长而逐趋明显。睡眠短期剥夺IL-1βmRNA表达增高可能对脑细胞具有应激性保护作用,而长期剥夺后IL-1β持续增高可能对神经元有损伤作用。
Objective: To investigate the effects of total sleep deprivation on IL-1βmRNA expression in rat's hippocampus and cortex. Methods: Put the rats in the rotating drums whose rotating rate were 1/min to make the TSD model in different time course. Divided the 30 rats into total five groups randomly: antitheses group(CC group for normal and TC group for environment) and sleep deprivation group ( TSD6h, TSD1 d, TSD3d (n=6)). we adopt the approach of RT-PCR to test IL-1βmRNA expression in rat's hippocampus and cortex. Results: The IL-1βmRNA expression of TSD6h group and TSD1d group was significantly higher than antitheses group within the hippocampus , especially TSD3d group; and also the expression of TSD3d group was significant increased within the cortex. Conclusion. Total sleep deprivation on IL- 1βmRNA expression in rat's hippocampus and cortex was higher, and the longer the time course, the more significant the result was. The higher IL-1βmRNA expression maybe help to protect the brain cell after short-time sleep deprivation, but they maybe harm the nerve cell after overtime in deprivation.
