Abstract
The effect of sulfur dioxide, nitrogen dioxide, nitric oxide, ozone, and formaldehyde on the ciliary activity of an excised specimen of the trachea of a guinea pig was investigated. The influence of these gases is determined by the Half Reduction Time of the ciliary activity, which is the time lapse from the beginning of the gas exposure at a certain concentration to the point of which the activity is reduced by half. The Half Reduction Time of the ciliary activity by each gas at the concentration of 50 ppM is SO/sub 2/, 4 min; HCHO, 5 min; NO/sub 2/, 10 min; NO, 14 min; and O/sub 3/, 20 min. The influence of the easily water soluble gases such as SO/sub 2/ and HCHO on the ciliary activity is severe compared with the less water soluble ones, NO/sub 2/ and O/sub 3/, which pass over the mucous surface of the upper airway without dissolving to the mucous layer.
