Interferon (IFN)-gamma and IL-10 cytokines, measures of Th1 and Th2 immunity, were examined in 20 healthy nonsmokers (12 males, 8 females) and 19 smokers (11 males, 8 females), aged 19-41 years (23.46+/-0.82 years). Nonsmokers came to the laboratory once; smokers came to the laboratory after ad lib smoking and following 24-h smoking abstinence. Salivary cotinine and expired CO confirmed smoking status. Plasma was collected at the end of each lab session and assayed for peripheral IFN-gamma and IL-10 levels. Among smokers, peripheral IFN-gamma, IL-10, or IFN-gamma/IL-10 ratio levels did not change in response to 24-h smoking abstinence. IFN-gamma levels and IFN-gamma/IL-10 ratios were higher among female smokers while smoking and following 24-h abstinence compared to male smokers in both conditions and compared to male and female nonsmokers. There was no sex or smoking status difference in IL-10 levels. Results suggest that cigarette smoking may have at least short-term damaging effects on the body's normal immune balance, particularly for women.
对20名健康非吸烟者(12名男性,8名女性)和19名吸烟者(11名男性,8名女性)进行了检测,他们的年龄在19至41岁之间(平均年龄23.46±0.82岁),检测指标为作为Th1和Th2免疫指标的干扰素(IFN)-γ和白细胞介素-10细胞因子。非吸烟者仅到实验室一次;吸烟者在随意吸烟后以及戒烟24小时后到实验室。唾液可替宁和呼出一氧化碳证实了吸烟状态。在每次实验室检测结束时采集血浆,检测外周血IFN-γ和白细胞介素-10水平。在吸烟者中,外周血IFN-γ、白细胞介素-10或IFN-γ/白细胞介素-10比值水平在戒烟24小时后没有变化。在吸烟时和戒烟24小时后,女性吸烟者的IFN-γ水平和IFN-γ/白细胞介素-10比值均高于男性吸烟者,且高于男性和女性非吸烟者。白细胞介素-10水平在性别或吸烟状态上没有差异。结果表明,吸烟可能至少对身体的正常免疫平衡有短期损害作用,尤其是对女性。
