Abstract
Cigarette smoke exposure imapired the mucociliary transport on the tracheal mucosa of pigeons. N-acetylneuraminic acid (NANA), but not lactose, dose-dependently protected against the impairment of the mucociliary transport. The results suggest the NANA, a representative sialic acid existing on the airway epithelium, may participate in the defence mechanism in the respiratory tract against irritant gases.
