[The circadian rhythm of ciliary beat frequency of human nasal cilia in probands with healthy lungs and in patients with chronic obstructive lung disease. Includes adrenergic stimulation by terbutaline].

Brush biopsies taken from the human nose eight times during 24 hours were examined under a phase contrast microscope and the ciliary beat frequency was measured directly by a photosensitive cell. Ten healthy volunteers showed in two series of measurements, at 600, 1200, 1800, 2400 initially and 300, 900, 1500, 2100 six weeks later, a marked decrease in… CONTINUE READING
