Acute inhalation toxicity of polymeric diphenyl-methane 4,4′-diisocyanate in rats: time course of changes in bronchoalveolar lavage
In summary, this study suggests that respirable poly- meric MDI aerosol interacts directly with the air/blood barrier causing increased extravasation of plasma con- stituents as a result of increased permeability of capillary endothelial cells.
