吸烟和被动吸烟对青少年免疫系统的危害

Study on hazards of smoking and passive smoking on adolescents′ immune system

目的了解吸烟及被动吸烟对青少年免疫系统的危害。方法从参与体检的在校学生中选取20例吸烟者、20例被动吸烟者、20例不吸烟者,分为三组,检测其T细胞亚群(CD3+、CD4+、CD8+、CD4+/CD8+)含量、免疫球蛋白(Ig G、Ig A、Ig M)含量,并对吸烟组吸烟指数与免疫水平的高低进行相关性分析。结果吸烟者和被动吸烟者相对不吸烟者,T细胞亚群和免疫球蛋白含量明显降低;吸烟组吸烟指数与机体免疫水平呈明显负相关。结论吸烟和被动吸烟会严重危害青少年机体的免疫系统。

Objective To understand the hazards of smoking and passive smoking on the adolescents′ immune system.Methods Three groups,including 20 smokers,20 passive smokers and 20 non-smokers were selected from the students who participated in physical examination.Their T cell subsets（CD3＋,CD4＋,CD8＋and CD4＋/CD8＋） contents and immunoglobulin（Ig G,Ig A and Ig M） contents were detected.And correlation analysis of the smoking index and the immune level was conducted in the smoking group. Results Compared to non-smokers,smokers and passive smokers had significantly reduced T cell subsets and immunoglobulin contents.The smoking index and the body immune level in smokers was negatively correlated. Conclusion Smoking and passive smoking will severely impair the adolescents′immune system.
