Abstract
In order to determine the effect of surgical trauma on neutrophil functions, we set up an experimental abdominal surgical model using rats and analyzed neutrophil functions. In addition, we measured tumor necrosis factor-alpha (TNF-alpha), cytokine-induced neutrophil chemoattractant/growth-regulated oncogene (CINC/GRO) and nitric oxide (NO) production. Male Sprague-Dawley rats, 8 weeks old and weighing 250-270 g, underwent laparotomy (4 rats for each experiment). After the operation, neutrophil chemotaxis was assayed using a modified Boyden chamber, and phagocytosis, active oxygen production and adhesion molecule expression were analyzed by flow cytometry. TNF-alpha and CINC/GRO levels were quantified by an immuno-dot-blot assay, and NO levels were measured by the Griess method. At the operation, NO inhibitor, N(G)-monomethyl-L-arginine acetate (L-NMMA, 40 mg) was intraperitoneally administered, and the effect of L-NMMA was studied. After the surgical trauma (24-48 h), blood neutrophil counts significantly increased (p < 0.001), and neutrophil chemotaxis, phagocytosis and active oxygen production were markedly enhanced (p < 0.01). Moreover, up-regulation of Mac-1 and down-regulation of L-selectin on neutrophils were observed (p...Continue Reading
