β-内啡肽、甲状腺激素及肾上腺皮质激素在军事应激时的变化

The changes in β-endorphin, thyroid hormone, corticol hormone levels in military exercise stress

目的:以实弹射击考核为应激源,研究新战士在军事应激状态下应激激素的变化。方法:选择42名新战士,在射击考核前半个月平静状态下抽血为对照组;实弹射击考核后就地抽血为实验组,利用放射免疫分析技术分别对β-内啡肽(β-EP)、甲状腺激素(T_3、T_4)、肾上腺皮质醇激素(Cort)进行测定。结果:应激时β-EP、Cort激素升高明显(P<0.01,P<0.001),而T_3结果偏低,与应激前比较差异显著(P<0.01),T_4结果在应激时虽有升高,但无统计学意义(P>0.50)。结论:军事应激可导致体内应激激素水平的变化,因此,建立应激激素的检测,对于提高军事应激能力,保障部队指战员的身心健康具有重要价值。

Objective:To investigate the changes in stress hormones when raw recruits were engaged in military exercise. The stress was an examination in a shooting range. Methods:Forty-two raw recruits were included in the present study, and their blood samples were collected when they were in stress and at rest. Contents in blood of β-endorphin (β-EP), thyroid hormone, and adrenal cortical hormone were determined with radioimmunoassay.Results: The contents of β-EP and adrenal cortical hormone in stress were higher than that at rest (P<0.001,P<0.01). The content of T_3 in stress was lower than that at rest, and the difference was significant (P<0.01). Although the content of T_4 rose in stress, the difference was not significant compared with that at rest (P>0.05). Conclusion: Military exercise stress could produce changes in stress hormones. Detection of stress hormones might he helpful for the evaluation of the ability of military personnel to enduce the stress produced by military activities.
