目的 研究跳伞训练对新老兵应激程度和某些免疫指标的影响。方法 随机选择空降兵某部参加跳伞训练的新兵与老兵各１０名，均为男性，年龄１７～２２ 岁，对照组为同部卫生队不参加跳伞的卫生兵１０名，年龄及文化程度同前相当。跳完伞后１～２ 小时内采取静脉血，离心后抽取血清于－ ２０℃冰冻保存。在西京医院检验科用放射免疫法检测血清皮质醇浓度和ＩｇＡ、ＩｇＧ、ＩｇＭ 浓度。结果 新兵组ＩｇＡ 、ＩｇＧ与对照组差别显著，老兵组与对照组差别不显著，新老兵ＩｇＭ 都较对照组升高，但新兵ＩｇＭ 较对照组升高不显著，而老兵组升高达显著水平。结论 新兵在跳伞应激状态下免疫功能受抑制，但老兵免疫能力没有下降，某些免疫指标还有增高，表明老兵跳伞应激的反应是适度的，严重的跳伞应激可通过多次的训练而得以减轻
Objective To study the effect of parachuting training on the stress level and certain immune parameters of new veterans. Methods A total of 10 recruits and veterans who participated in parachuting training were randomly selected, each of whom was male, aged 17-22 years. The control group consisted of 10 health workers who did not participate in skydiving in the same department, with the same age and education . After jumping the umbrella to take 1 to 2 hours to take venous blood, after centrifugation, the serum was drawn and frozen at -20 ℃. Serum cortisol concentration and IgA, IgG and IgM concentrations were detected by radioimmunoassay in Xijing Hospital. Results There was significant difference between the new recruits group and the control group. There was no significant difference between the veterans group and the control group. The IgM of the new veterans was higher than that of the control group. However, the recruit IgM level was not significantly higher than that of the control group. CONCLUSION: The recruits are suppressed in the parachute stress immune function, but the veterans immunity did not decline, and some immune indicators also increased, indicating veteran parachute stress response is modest, serious parachute stress can be repeated training And be relieved
