Özet

Background: We tested the hypothesis that lung injury after intestinal ischemia-reperfusion (IR) requires the activation of CD11/CD18 glycoprotein complex and its ligand, intracellular adhesion molecule-1 (ICAM-1), on pulmonary endothelial surface. Methods: Rats were assigned to one of six groups including sham operation, intestinal IR (60/120 min) and IR plus treatment with one of the following antibodies against CD11a, CD11b, CD18, and ICAM-1. Pulmonary microvascular permeability, neutrophil accumulation, and expression of adhesion molecules were evaluated. Results: Intestinal IR resulted in lung injury characterized by a marked increase in microvascular permeability, neutrophil accumulation and upregulated expression of leukocyte integrins and ICAM-1. The increase in pulmonary microvascular permability and neutrophil accumulation elicited by intestinal reperfusion was effectively prevented by administration of blocking antibodies against ICAM-1, CD11, and CD18. Conclusions: These results indicate that adhesion molecules contribute to the lung injury after intestinal IR. Immunoneutralization of certain of these adhesion molecules may present intestinal IR-induced lung injury. (C) 2002 Excerpta Medica, Inc. All rights reserved.
