Bronchoalveolar Cell Profiles of Asthmatic and Nonasthmatic Subjects

Asthma is associated with increased airway responsiveness to pharmacologic agents such as methacholine. Increases in airway responsiveness after exposure to allergen or ozone are associated with increased inflammatory cells in bronchoalveolar lavage both in human and in animal studies. We studied the total and differential cell counts in 10 stable atopic asthmatics who had airway hyperresponsiveness but no clinical features of airway …
