The effect of brewery dust extracts was studied using water-soluble extracts of dust obtained from brewery materials, including hops, barley, and brewery yeast. ... We suggest that brewery dust extracts cause a dose-related airway smooth muscle constriction by nonimmunologic mechanisms involving a variety of airway mediators.
