目的 研究新鲜血细胞对细胞性抗原快速天然免疫反应的变化规律。方法 细菌(酵母菌、大肠埃希菌、铜绿假单胞菌 )加入枸橼酸抗凝血中 37℃水浴 30min。结果 红细胞酵母菌的快速天然免疫黏附反应明显高于白细胞酵母菌的快速天然免疫黏附反应(P<0 0 1 ) ,红细胞对大肠埃希菌的凝集型天然免疫黏附反应可被EDTA阻断 ,但红细胞对大肠埃希菌的黏附型天然免疫黏附反应不能被EDTA阻断。结论 血细胞存在多种形式的天然免疫黏附反应性 ,红细胞在新鲜血快速天然免疫黏附反应中具有多种作用
Objective To study the regularity of rapid natural immune response of fresh blood cells to cellular antigens. Methods Bacteria (yeast, Escherichia coli, Pseudomonas aeruginosa) were added to citric acid anticoagulant in a 37 ° C water bath for 30 min. Results The rapid natural immune adhesion reaction of erythrocytic yeast was significantly higher than that of leukocyte yeast (P <0.01). The agglutination-type natural immune adhesion reaction of erythrocyte to Escherichia coli could be blocked by EDTA. However, Erythrocyte adhesion to Escherichia coli type of natural immune adhesion reaction can not be blocked by EDTA. Conclusion There are many forms of natural immune adhesion reactivity of blood cells, and erythrocytes have multiple roles in the rapid natural immune adhesion reaction of fresh blood
