本研究观察了100例健康人和30例慢性支气管炎患者吸入菜籽油烟雾前后气道功能的变化。结果健康组和慢支组PEFR,V75,V50,V25均显著下降,慢支组FVC和FEV1也明显降低。表明菜籽油烟雾吸入对健康人气道有刺激和损伤作用,可致气道收缩,阻力增加,这种刺激和损伤对有气道慢性炎症者更为剧烈,长期接触厨房油烟可能是中国人COPD的环境因素之一。
In this study, we observed changes of airway function in 100 healthy subjects and 30 patients with chronic bronchitis before and after inhaling rapeseed oil smoke. Results The PEFR, V75, V50 and V25 in both healthy group and chronic bronchitis group were significantly decreased, while the FVC and FEV1 in chronic bronchitis group were significantly decreased. Show that rapeseed oil smoke inhalation of healthy human airways have a stimulating and damaging effect, can cause airway contractions, increased resistance, this stimulation and injury of airway chronic inflammation are more severe, long-term exposure to kitchen fumes may be Chinese COPD One of the environmental factors.
