[The impaired upper respiratory environment as a criterion for a risk of respiratory diseases in firemen]

Abstract

Microbiocenoses were qualitatively and quantitatively determined; the cytomorphological parameters of the upper respiratory tract mucosae were studied, and the concentrations of SIgA were measured in the saliva of firemen. In the latter, nonspecific infection resistance was found to diminish due to the influence of poor occupational factors. A strong correlation was found between the influencing factors and the development of upper airway diseases; the latter were greatly affected by occupational factors.
