ABSTRACT
<p><b>OBJECTIVE</b>To investigate the role of intercellular adhesion molecule-1 (ICAM-1) in the accumulation of polymorphonuclear neutrophils (PMN) in the lungs at the early stage of burns.</p><p><b>METHODS</b>Myeloperoxidase content in lung tissues and bronchoalveolar lavage fluid (BALF) were detected. ICAM-1 and its mRNA expression in lung tissues were determined by immunohistochemical method and in situ hybridization. CD11b/CD18 expression on the peripheral PMNs was measured by flow cytometry.</p><p><b>RESULTS</b>The levels of myeloperoxidase in lung tissues and BALF after burn injury were markedly higher than those of control. Expression of ICAM-1 and its mRNA in the lung tissues and CD11b/CD18 on peripheral PMNs surface was significantly increased at 2, 6, 12, 24 h after burns.</p><p><b>CONCLUSIONS</b>PMNs accumulation in the lungs is related to increased ICAM-1 expression on pulmonary microvascular endothelial cells and CD11b/CD18 expression on PMN at the early stage of burn injury.</p>
