PURPOSE To investigate whether serum levels of lipid peroxides measured as thiobarbituric-acid-reactive substances (TBARS) differ in type I and type II diabetic patients, whether serum levels correlate with late sequelae of diabetes, and whether serum levels of free vitamin E correlate with levels of lipid peroxidation by-products.

Human umbilical vein endothelial cells (HUVEC) were investigated for their ability to produce neopterin, a biochemical marker for an activated immune system. Interferon-gamma (IFN-gamma), IL-1 alpha, IL-2, IL-6, tumour necrosis factor-alpha, granulocyte/macrophage colony stimulating factor, phytohaemagglutinin and concanavalin A were used to stimulate(More)
The rejection of a transplanted heart leads to an accumulation of mononuclear cells in the cardiac tissue and to reactions of the antigen-recognizing cells with the foreign tissue. Consequently, during rejections immunologic changes, such as the number of mononuclear cells and the patterns of mononuclear cell subpopulations, should be detectable by analysis(More)
OBJECTIVE To determine the expression of tumor necrosis factor (TNF) receptor in patients with systemic inflammatory response syndrome (SIRS). DESIGN Prospective study. SETTING Intensive care unit and central laboratory. PATIENTS Blood specimens from 18 healthy volunteers (controls) and 16 patients with SIRS. INTERVENTIONS None. MEASUREMENTS AND(More)
OBJECTIVES The aim of our study was to investigate the usefulness of tissue polypeptide specific antigen, an established tumor marker detecting proliferation of cells, for monitoring heart transplant recipients in order to detect infection and rejection early. METHODS Tissue polypeptide specific antigen serum levels were compared with neopterin and(More)
Fc gamma RIII (CD16) expression of neutrophil granulocytes was measured in 156 patients by means of fluorescence-labeled antibodies with a flow cytometer. Results were compared with (1) 400-cell manual differential count; (2) left shift flagging on hematology analyzers; (3) absolute neutrophil count; and (4) acute-phase protein levels. Asynchrony was noted(More)
Flow cytometry using fluorescence-labelled monoclonal antibodies has been proposed as a possible new reference method to evaluate the monocyte counting performance of automated hematology analyzers. Since in previous studies only one such technique was applied, we investigated how different flow cytometric techniques compared to the manual differential and(More)
A flow cytometric method performing a five-part leukocyte differential based on three-color staining with anti-CD45-fluorescein isothiocyanate (FITC), anti-CD-14-phycoerythrin (PE)/Cy5, and a cocktail of PE-labeled anti-CD2, anti-CD16, and anti-HLA-DR antibodies was evaluated. Results obtained by using three different sample preparation procedures and two(More)
Flow cytometric enumeration of monocytes stained with fluorescence-labelled monoclonal antibodies has been proposed as a possible reference method for monocyte counting. We compared precision and accuracy of monocyte counting of the Coulter STKS, the Cobas Argos 5 Diff, the 800-cell manual differential, and the Coulter Epics Profile II flow cytometer using(More)
