Effect of lipopolysaccharide of Haemophilus influenzae on ciliary activity of the human nasal mucosa and bullfrog palate clearance.

The influence of lipopolysaccharide (LPS) of Haemophilus influenzae on the ciliary activity of human nasal mucosa was first studied using both a photo-oscillographic apparatus and by bullfrog palate clearance. Neither modification of ciliary activity nor change in bullfrog palate clearance was observed in the early phase after the administration of LPS.
