Effects of heparin on hypertonic potassium chloride-induced bronchoconstriction

Abstract

BACKGROUND: Changes in bronchial osmolarity Is a well-known factor for bronchoconstriction. Recently, nonisotonic aerosols have begun to be used for the assessment of bronchial hyperreactivity. Hypertonic KCl can cause bronchoconstriction even in nonsymptomatic asthmatic patents.
