THE EFFECT OF HUMAN ANTIENDOTOXIN MONOCLONAL-ANTIBODIES ON ENDOTOXIN-INDUCED LUNG INJURY IN THE RAT AMERICAN REVIEW OF RESPIRATORY DISEASE Feeley, T. W., MINTY, B. D., Scudder, C. M., Jones, J. G., Royston, D., Teng, N. N. 1987; 135 (3): 665-670

Abstract

A model of endotoxin-induced lung injury was developed in the rat. We found that 24 h after intravenously administered endotoxin (3 mg/kg) there was increased clearance of the isotope 99mTcDTPA from the lung to blood, increased neutrophils in the lung in bronchoalveolar lavage, and increased levels of products of peroxidation of lipids and nucleic acid in the serum. Using this model, we evaluated the effect of pretreatment of rats with a human monoclonal antibody specific to the core glycolipid that is common to all endotoxins. We found that pretreatment prevented the increased clearance of 99mTcDTPA from the lung, as well as the increase in lipid peroxidation products in the serum. The antibody did not prevent increased neutrophil accumulation in the lung. The findings suggest that the administration of human antiendotoxin monoclonal antibodies prior to endotoxemia may prevent some of the changes in the lung associated with endotoxin.
