Abstract

目的 研究睡眠剥夺对循环免疫细胞的影响.方法 24只大鼠分为睡眠剥夺组、实验对照组和正常对照组,给予睡眠剥夺组72h睡眠剥夺处理.检测血细胞的数量和比例以及循环T细胞亚群和脾淋巴细胞的细胞周期.结果与正常对照组比较,实验对照组和睡眠剥夺组的白细胞(12.74×10 12/L vs. 7.94×10 12/L vs. 7.08×10 12/L)、淋巴细胞(9.51×10 12/L vs. 5.61×10 12/L vs. 5.18×10 12/L)和中性粒细胞(2.59×10 12/L vs. 1.84×10 12/L vs. 1.39×10 12/L)显著减少(P <0.05或P <0.01);睡眠剥夺组的单核细胞比例(3.85% vs. 6.54%)显著增高(P <0.05);睡眠剥夺组与实验对照组之间无显著差异.各组T细胞亚群和脾淋巴细胞的细胞周期均无显著差异.结论 72h睡眠剥夺对循环免疫细胞、T细胞亚群以及脾淋巴细胞的增殖功能无显著影响。
