摘　　要：目的 观测低频脉冲电磁场对飞行人员甲皱微循环的影响,为在临床上用于增强飞行人员身体素质,改善飞行疲劳,提高防病抗病能力提供理论根据. 方法 选择健康飞行人员50名,采用120 mt低频脉冲电磁场作用于受试者左肘关节屈侧20 min,于作用前和作用后即刻各观测甲皱微循环1次. 结果 低频电磁场作用后,有82%的人微血管数目无变化或增加.微血管形态以扩张为主,作用后微血管扩张人数占78%.微血管口径较作用前增大明显(t=2.301～3.436,p<0.05),差异有统计学意义.袢长较作用前明显增长(t=13.060,p<0.01),差异有统计学意义.微血管的血流速度作用后明显加快,血流流态为线流或线粒流两个级别的人数明显增多(x2=18.136,p<0.01),差异有统计学意义. 结论 低频脉冲电磁场作用于机体特定部位后可减少飞行人员微循环变异,改善其微循环状态.objective to investigate the effects of low frequency electromagnetic field (lfemf) on nail fold microcirculation of healthy aircrew, so as to provide scientific basis for maintaining aircrew's health, relieving fatigue in flight and enhancing immunity from disease. methods fifty healthy aircrews were selected as subjects. lfemf was applied at 120 mt to the flexor aspect of left elbow of the subject's for 20 min. subject's nail fold microcirculation was respectively measured before and after test. results due to lfemf effect the number of capillary of 82% subjects' was kept constant or increased. measurement on 78% subjects showed capillary dilation on form and structure and that was the common effect of lfemf. lfemf also resulted in the diameter of capillary significantly increased (t=2.301-3. 436, p<0.05), the length of capillary loops was significantly increased by lfemf (t= 13. 060, p<0.01 ), as well as the velocity of blood flow (x2=18. 136, p<0. 01). conclusions applying lfemf to specific area of human body may reduce the variation of blood microcirculation and improve microcirculation state.
