Effects of nitrogen dioxide on pulmonary cell population.
Studies from this laboratory have shown that ozone produces changes in the number and function of cells obtained by pulmonary lavage. In similar experiments, rabbits exposed to levels of NO(2) from ambient to 60 ppm demonstrated increased numbers of polymorphonuclear leukocytes in the lung washings. This phenomenon persisted for more than 72 hr after a single 3-hr exposure. When streptococci we...
متن کاملInfluence of experimental pulmonary emphysema on the toxicological effects from inhaled nitrogen dioxide and diesel exhaust.
This project examined the influence of preexisting, experimentally induced pulmonary emphysema on the adverse health effects in rats of chronic inhalation exposure to either nitrogen dioxide or automotive diesel-engine exhaust. Previous reports indicated that humans with chronic lung disease were among those most severely affected by episodic exposures to high concentrations of airborne toxican...
متن کاملThe effects of continuous high level nitrogen dioxide on hamsters.
Approximately eight years ago we1 became interested in the use of nitrogen dioxide as an agent to produce experimental lung injury. At that time our interest in this agent was prompted by reports that it was capable of producing bronchiolitis obliterans in accidental human exposures,` and because the early experimental work of Winternitz,' et al. directed our attention to the ability of certain...
متن کاملMorphological effects of nitrogen dioxide on the rat lung.
Morphological studies of the rat lung exposed to 20 ppm NO2 for 20 hr (experiment 1), to 0.5 ppm for 19 months (experiment 2), and to 10 ppm for 14 days (experiment 3) were conducted. Changes in the mast cells of the tracheas and main bronchi of rats exposed to 0.5 ppm (experiment 4) were also observed. In the alveolus, cytoplasmic blebbing occurred in a small number of type I cells immediately...
