Unsedated animal models of pulmonary mucociliary transport.

Measurements of the rate of mucociliary transport in the airways of the lower respiratory tract have been shown to be influenced by the techniques and protocols used. To avoid the effects associated with invasive techniques and anesthesia in animal models used to study the effect of maturation, drugs, disease, and inhaled pollutants on mucociliary transport we have developed unsedated dog and baboon models of mucociliary transport using radioaerosol techniques. As far as they have been tested these animal models of mucociliary transport react to drugs such as isoproterenol and atropine in the same manner as in man.
