乌拉地尔降低脑温的实验研究

目的 研究高温高湿环境下乌拉地尔降低脑温的效果. 方法 选取90名南沙巡防区战士,分成老战士组、新战士组、新战士服药组(口服乌拉地尔片剂)3组,在湿热环境下20 min内跑步3000 m,测定跑步前后的体温,以反映脑温的变化. 结果跑步前3组战士之间的体温没有明显差别,跑步后3组战士之间的体温改变差异有统计学意义(P<0.05),其中新战士服药组上升幅度最小,新战士组升高幅度最大. 结论 高温高湿环境中新、老战士出现的耐受和适应情况不同,口服乌拉地尔片剂可以明显降低脑温.

Effect of urapidil in reducing brain temperature in hot and humid environment

Objective To investigate the effect ofurapidil in lowering the brain temperature in hot and humid environment. Methods Ninety soldiers stationed in Chinese Nansha Islands were divided into veteran group, untreated new recruit group and new recruit group with urapidil (tablet) treatment. All the soldiers were asked to complete a running exercise for 3000 m within 20 min in hot and humid environment, and their body temperature before and after the exercise was measured to evaluate the brain temperature changes. Results Before the running exercise, no significant differences was found in the body temperature among the 3 groups. The body temperature of the soldiers showed significant differences after the exercise, and the untreated new recruit had the most obvious elevation of the body temperature, whereas those with urapidil treatment showed the least elevation. Conclusion Veterans and new recruit show different tolerance and adaptability to hot and humid environment, and urapidil tablets can help reduce brain temperature increment induced by hot and humid environment.
