摘　　要：目的探讨飞行训练对飞行学员前庭功能及血浆促肾上腺皮质激素(ACTH)水平的影响。方法对517例男性飞行学员和314例地面人员进行检测。在黑暗环境中采取90(°)/s恒速旋转后急停刺激模式,记录受检人员眼震电图。对相关数据进行统计学分析。在接受刺激前后,分别采集2组参试人员血液,用放射免疫分析法测定血浆ACTH水平,观察旋转刺激对血浆激素水平的影响。结果与地面人员比较,飞行学员垂直眼震的最大慢相速度降低(P<0.05),慢相速度衰减时间常数延长(P<0.05)。刺激前后飞行学员组的血浆ACTH水平均高于地面人员,尤其是旋转刺激后的ACTH水平。结论飞行学员经过飞行训练后产生了前庭习服,体内血浆的ACTH基础水平升高。Objective To study the influence of the flight training on flying cadets＇ vestibular function and adrenocorticotropic hormone （ACH） levels of plasma.Methods Five hundred and seventeen male flying cadets and 314 ground personnels were tested.The stimulus mode of emergency stop after 90（o）/s constant speed rotation was adopted in the dark environment.The electronystagmography （ENG） of research objects was recorded.The relevant data were analyzed statistically.The blood of the two groups were collected before and after the stimulation.The radioimmunoassays were used to determine the ACTH levels of plasma.The effect of rotation stimulation on ACTH levels of plasma was observed.Results As compared with those of ground personnel,the maximum slow-phase speed （SPEV） of vertical nystagmus on flying cadets significantly decreased （P ＜0.05）,attenuation time constant of SPEV significantly increased in flying cadets （P ＜ 0.05）.ACTH levels of plasma in flying cadets were higher than those of the ground personnel before and after the stimulation,especially the ACTH levels of plasma after rotation stimulation were obvious.Conclusions Flying cadets breed vestibular habituation after a long flight training,the basis ACTH levels of plasma in the body increased.
