title: Lipopolysaccharide (LPS) inhalation in healthy subjects causes bronchoalveolar neutrophilia, lymphocytosis, and fibronectin increase.
abstract: Eight healthy volunteers were exposed to purified lipopolysaccharide (LPS) by controlled inhalation. Bronchoalveolar lavage (BAL) 3 hours after exposure revealed a pronounced neutrophilia, increase in lymphocytes, fibronectin concentration, and decrease in alveolar macrophage phagocytosis, as compared to a reference BAL.
