以前我们是用生化和免疫学的综合方法检查职业活动条件下飞行员的涎腺液体的。唾液中所测成分和指标中最有意义的是钠电解液和分泌性IgA,因为它们是放出适应性激素的间接指示器,常受应激因素的影响,而且在飞行活动中它们在唾液中的含量比其它成分的浓度变化明显。 In the past we used biochemical and immunological methods to examine pilots’ salivary glands under occupational conditions. Among the components and indices measured in saliva, sodium electrolytes and secretory IgA are the most significant because they are indirect indicators of adaptive hormones and are often affected by stressors and their role in flight during saliva Concentration of the content of other components than obvious changes.
