  • Look Inside

To determine whether atypical β-adrenoceptor (β3- adrenoceptor) agonist, BRL 37344, stimulates airway ciliary motility and, if so, what its mechanism of action is, we studied rabbit tracheal epithelium in vitro. Epithelial cells cultured for 7 days were mounted in the Rose chamber and ciliary beat frequency (CBF) was measured by a photoelectric method. Addition of BRL 37344 rapidly increased CBF from 15.5±0.6 to 20. 3±1.4 Hz (mean±SE, p<0.01), which remained ele-vated for at least 20 min.
