目的 比较红细胞对细菌的天然免疫粘附能力。方法将细菌（大肠杆菌等）加入红细胞液悬液中３７℃水浴３０分钟。结果肿瘤患者红细胞对细菌（大肠杆菌等）的免疫粘附反应能力比正常人低（Ｐ＜０．０１）。结论 红细胞对细菌有天然免疫粘附反应。有关红细胞对细菌的天然免疫反应能力的测定在临床上有应用价值。
Objective To compare the natural immune adherence of erythrocytes to bacteria. Methods Bacteria (E. coli, etc.) were added to the erythrocyte suspension in a 37 ° C water bath for 30 minutes. Results The erythrocytes in cancer patients had less ability of immune adherence to bacteria (such as Escherichia coli) than the normal people (P <0.01). Conclusion Erythrocytes have innate immunity to bacteria. The determination of the natural immune response of erythrocytes to bacteria has clinical value.
