The Effect of Aspirin on Lung Mucociliary Clearance

Abstract
THE removal of inhaled particles, bacteria, and cellular debris by mucociliary clearance has an important role in the maintenance of healthy lungs. Particles are carried on mucus that is transported cephalad on the tips of beating cilia that are immersed in a layer of serous fluid.1 When the mucus reaches the pharynx it is swallowed along with the transported particles.The efficiency of mucus transport in individual airways and whole-lung mucociliary clearance has been investigated in health and disease and in response to various drugs and toxic agents.2 3 4 5 6 7 8 9 10 11 12 13 In vitro studies in animals have demonstrated an increase in the rate . . .
