Abstract

Clinical studies have indicated increased gelatinase activity in the airways of patients suffering from chronic obstructive pulmonary disease caused by tobacco smoke. The present study aimed to determine whether acute exposure to tobacco smoke per se causes a substantial and lasting impact on gelatinases and their inhibitors in the peripheral airways of atopic and nonatopic human subjects. Bronchoscopy with bronchoalveolar lavage (BAL) was performed on occasional smokers with and without atopy before and after smoking 10 cigarettes over a 48-h period. Samples from a group of never-smokers not exposed to tobacco smoke served as controls. Gelatinase identity and activity were measured using zy..
