[Expiration of endogenous aerosol in chronic bronchitis and bronchial asthma patients]

The amount of expired endogenous aerosol in liquid drop and solid phases, 0.1-10.0 micron in diameter, in patients exceeded the normal indices. The nature of solid aerosol particle distribution by sizes was related to a degree of bronchial obstruction. The amount of both types of aerosols showed correlation with the amount of expectorated sputum.
