Mice have been used in studies of the immunology or pathology of several different disorders affecting the lung. However, the value of the mouse for the analysis of pulmonary pathophysiology has been limited by the lack of methods for measuring lung function in the living animal. We report here the first method for measuring pulmonary conductance (GL) and compliance (Cdyn) in tracheostomized mechanically ventilated mice. We used this method to characterize the mouse's pulmonary responses to several putative bronchoconstrictor agonists. GL and Cdyn were decreased by intravenous infusions of methacholine, norepinephrine, or serotonin. Reproducible responses were not detected after infusions of histamine, prostaglandins D2 or F2 alpha, leukotrienes C4 or D4, substance P, or platelet-activating factor. The pattern of airway responsiveness to these agonists in the mouse is similar to that reported for the rat; in contrast to the rat, the mouse has many well-characterized strains or mutants with deficiencies of immunologic or inflammatory cells or mediators. As a result, this model offers unique advantages for identifying the roles of individual inflammatory cell types or mediators in pulmonary processes, including pulmonary anaphylaxis.
