目的 旨在探讨吸烟对飞行员体液免疫功能的影响。方法 ８８ 例飞行员依是否吸烟分为吸烟组（ｎ ＝ ４３） 和非吸烟组（ｎ ＝ ３５） ，其中吸烟组平均年龄为３７ ±５－８ 岁，非吸烟组平均年龄为３８ ±７－８ 岁。血清免疫球蛋白Ｇ、Ｍ、Ａ 等采用快速免疫消浊法进行定量分析。结果 吸烟组飞行员的血清免疫球蛋白Ｇ、Ｍ、和Ａ 等平均水平均显著低于非吸烟组（ Ｐ ＜ ０ ．０１） 。结论 吸烟确能降低飞行员的血清免疫球蛋白水平，结果可能损害其体液免疫功能。
The purpose is to investigate the effect of smoking on the humoral immune function of pilots. Methods 88 pilots were divided into smoking group (n = 43) and non-smoking group (n = 35) according to whether they smoked or not. The mean age of smoking group was 37 ± 5-8 years and that of non-smoking group was 38 ± 7-8 year old. Serum immunoglobulin G, M, A and other rapid immunoassay method for quantitative analysis. Results The mean levels of serum immunoglobulins G, M, and A in pilots of smoking group were significantly lower than those of non-smoking group (P <0.01). Conclusions Smoking does reduce the level of serum immunoglobulin in pilots, which may impair its humoral immune function.
