Lung function and morphology of dogs after sublethal exposure to nitrogen dioxide.

Abstract

The relationship between respiratory function and morphological changes in 10 dogs exposed for 6 h to 69 ppm nitrogen dioxide was studied. Two additional dogs served as controls. Functional assessments included breathing pattern, breathing mechanics, forced expiration, gas exchange, and acid-base status. Gross, microscopic, and ultrastructural evaluations… (More)
