Clinical Diagnostic for the Quantitative Analysis of Leukocyte Phagocytosis in Human Whole Blood</p>
<p><strong>SUMMARY and EXPLANATION</strong></p>
<p>PHAGOTEST&reg; is a complete diagnostic kit for the investigation of the phagocytic function of granulocytes and monocytes [1, 2] in whole blood. This test kit allows the quantitative determination of leukocyte phagocytosis in heparinized whole blood. It contains fluorescein (FITC) labelled opsonized bacteria (E. coli-FITC) and necessary reagents. It measures the overall percentage of monocytes and granulocytes showing phagocytosis in general (ingestion of one or more bacteria per cell) and the individual cellular phagocytic activity (number of bacteria per cell). The evaluation of the results can be done either by flow cytometry or by fluorescence microscopy.</p>
<p><strong>摘要及说明</strong></p>
<p>PHAGOTEST是一个完整的诊断试剂盒用于研究单核细胞吞噬功能的全血粒细胞[1,2]。这个测验套件在全血的肝素化同意定量检测白细胞吞噬功能。它包含荧光素(牛血明净蛋白)标志过的使(真菌)易受调理素作用细菌(大肠杆菌牛血明净蛋白)和必要的试剂。它能测量单核细胞的总百分比和一般情况下粒细胞单核细胞吞噬(每个细胞摄入的一个或多个细菌)和个体细胞的吞噬活性(每个细胞的细菌数量)。测验的结果能够通过流式细胞术或荧光显微镜显示。</p>
<p><strong>APPLICATIONS</strong></p>
<p>PHAGOTEST&reg; is intended to investigate the phagocytic activity found in various disorders and to evaluate the effects of drugs. Abnormal phagocytosis can occur with a variety of clincal disorders (3, 4). The defects can be associated with the neutrophil itself or with an immunoglobulin or complement defect. Known inborne defects are actin dysfunction, tuftsin deficiency and complement receptor C3bi deficiency. These deficiencies can result in increased susceptibility to infection due to defective neutrophil phagocytosis.</p>
<p>Acquired defects associated with altered phagocytic activity can be observed in trauma, diabetes, renal failure, and infection. Reduced phagocytosis was found in patients with recurrent bacterial skin and sinopulmonary infections (5), in patients with wound infections from burns (6), in patients with AIDS (7), in neonates or in elderly people.</p>
<p>Various immunomodulators (cytokines such as interleukin-2 or interferon-, lactic acid bacteria and plant extracts such as from Echinaceae Purpureae herba) can increase the phagocytic activity of neutrophils and monocytes. These effects can be investigated in vitro or ex vivo (8, 9).</p>
<p>PHAGOTEST&reg; also allows the study of the phagocytic activity of HL-60 promyelocytic leukemia cells or of isolated monocytes or macrophages.</p>
<p>The diagnostic kit is also applicable on blood of mice, rats, rabbits, dogs, cattle and other species.</p>

<p><strong>TEST PRINCIPLES</strong></p>
<p>Phagocytosis by polymorphonuclear neutrophils and monocytes constitutes an essential arm of host defense against bacterial or fungal infections. The phagocytic process can be separated into several major stages: chemotaxis (migration of phagocytes to inflammatory sites), attachment of particles to the cell surface of phagocytes, ingestion (phagocytosis) and intracellular killing by oxygen-dependent and oxygen-independent mechanisms (1, 2).</p>
<p>PHAGOTEST&reg; allows the quantitative determination of leukocyte phagocytosis (ingestion of bacteria). It measures the percentage of phagocytes which have ingested bacteria and their activity (number of bacteria per cell). The phagocytosis test kit contains fluorescein-labelled opsonized Escherichia coli bacteria and other necessary reagents. Heparinzed whole blood is incubated with the fluorescein-labelled E.coli bacteria at 37&deg;C, a negative control sample remains on ice. The phagocytosis is stopped by placing the samples on ice and adding QUENCHING SOLUTION. This solution allows the discrimination between attachment and internalization of bacteria by quenching the FITC fluorescence of surface bound bacteria leaving the fluorescence of internalized particles unaltered. After two washing steps with WASHING SOLUTION erythrocytes are then removed by addition of LYSING SOLUTION. The DNA STAINING SOLUTION, which is added just prior flow cytometric analysis, excludes aggregation artifacts of bacteria or cells. The percentage of cells having performed phagocytosis are then analyzed as well as their mean fluorescence intensity (number of ingested bacteria).</p>
<p>The E.coli bacteria are opsonized with immunoglobulin and complement of pooled sera. Cells of the phagocytic system (monocytes, polymorphonuclear neutrophils) have receptors for a complement component (C3b) and for the constant part of the immunoglobulin molecule (Fc) mediating the adhesion of the bacteria to the cell surface. By utilizing both opsonized and nonopsonized bacteria, which are also available, both opsonic capacity and phagocytosis can be measured at the same time. Thus, it can be determined whether abnormal phagocytosis is due to a failure in the opsonization process or to a defect in the ingestion capability of the phagocyte.</p>
