title: Pulmonary cellular dysfunction in endotoxin shock: metabolic and transport derangements.
abstract: Lung cell metabolic and ion transport alterations in endotoxin shock have been studied to elucidate mechanisms of endotoxin-induced pulmonary dysfunction. Glucose oxidation to lactate as well as to CO2 is significantly increased with a decrease in the lung ATP contents. Active Na+ transport is impaired, indicating an increase in lung intracellular fluid. The altered glucose metabolism and active ion transport could potentially contribute to lung edemagenesis in endotoxicosis.
