Background: Several basic studies have demonstrated that monocyte chemoattractant protein-1 (MCP-1) influences type 2 cytokine production and cell-mediated immunity. However, there have been few reports on the changes in serum MCP-1 levels in patients undergoing major thoracoabdominal surgery. In this study, we examined the kinetics of serum MCP-1 post-operatively and clarified its significance regarding the extent of surgical stress.

Background/aims: It has been reported that contrast computed tomography (CT) provides a rapid and accurate diagnosis of acute appendicitis, and could potentially prevent adverse appendectomy. In the present study, we evaluated the diagnostic value of precontrast CT combined with that of serum C reactive protein (CRP) concentration for right lower quadrant inflammatory diseases.

Methodology: One hundred consecutive patients who had rebound tenderness and muscular rigidity or guarding on right lower quadrant underwent an emergency abdominal CT without contrast medium and laboratory tests.

Sepsis was induced by well-controlled cecal ligation and puncture (CLP) in macrophage inflammatory protein 1alpha (MIP-1alpha)/CCL3 knockout (CCL3(-/-)) and severe combined immunodeficiency (SCID) mice. CCL3(-/-) mice and their littermates (CCL3(+/+) mice) treated with anti-CCL3 monoclonal antibodies were susceptible (0-20% survival) to CLP-induced sepsis, and CCL3(-/-) mice supplemented with recombinant (r)CCL3 (250 ng/mouse) and CCL3(+/+) mice were resistant (70-80% survival). The resistance of SCID mice to CLP was markedly improved by the rCCL3 administration (88% survival), and SCID mice treated with saline were shown to be middling resistant to the same CLP (45% survival).

Objectives: We previously reported that omega-6 fat emulsion increases cytokine production in burned rats. Effects of soybean oil emulsion on surgical stress responses and lymphocyte function according to the surgical severity have not been studied in detail. We investigated the effects of soybean oil emulsion, which contains 50% omega-6 fatty acid, on postoperative stress responses and cell-mediated immune function according to the severity of surgical stress.
