| Abstract |
The effects of single or multiple 3-hr inhalation exposures to ethylene dichloride (dichloroethane or DCE) on macrophage functions and pulmonary defense were evaluated. Single exposures to the TLV level of DCE (10 ppm) resulted in decreased pulmonary bactericidal activity and increased susceptibility to mortality from Streptococcus 2 zooepidemicus respiratory infection. Streptococcal-induced mortality was also increased after a single exposure to 5 ppm DCE. No increase in mortality was observed following single or 5 consecutive daily exposures to 2.5 ppm DCE. Single exposures to 10 ppm DCE significantly decreased the number of cells recovered by pulmonary lavage but did not affect alveolar macrophage inhibition of the proliferation of a tumor target cell in vitro, or the in vitro phagocytosis of (51)Cr-chicken red blood cells. The activity of the ectoenzyme leucine aminopeptidase was increased in alveolar macrophages of DCE-exposed mice. It is hypothesized that exposure of mice to DCE for 3-hr results in increased susceptibility to pulmonary bacterial infection by altering the functioning of the resident alveolar macrophage population.
