摘　　要：目的：观察并探讨重型肝炎时血中性粒细胞的形态变化及其意义。方法：２０例重型肝炎患者血中性粒细胞标本，常规固定、包埋制片、电镜检查。结果：所有患者的中性粒细胞均有明显异常，其改变程度与患者肝衰竭分期相平行。主要包括：中性粒细胞质变性，吞噬泡欠缺，细胞器及细胞颗粒减少，线粒体肿胀，细胞核浓缩等。核面积测量、线粒体和细胞颗粒电镜计数结果与上述改变一致。结论：该结果可视为严重肝病患者中性粒细胞功能减退及其对细菌易感性显著增高的形态学证据，患者中性粒细胞超微结构异常与肝衰竭之间可能有某些互为因果关系。AIM: To study the morphological changes of neutrophils in patients with severe hepatitis and discuss their significance. METHODS: 20 cases of neutrophils specimens prepared with routine methods were observed by electron microscopy. RESULTS: Abnormalities of neutrophils were observated in all patients, which paralleled closely with the stage of hepatic failure in patients. Main ultrastructrual changes included cytoplasm degeneration, want of pinocytotic vesicle and phagosone, decreased organelles and granules, mitochondria swelling, nucleus condensation, etc. Nuclear area measure, mitochondria and cell granules count were consistent with the above observation.CONCLUSION: This results could be regarded as a morphological evidence of the reduced neutrophil functions and the increased susceptibility to bacterial infection in patients with severe liver disease. A mutually causal relation may be existed between the ultrastructural abnormalities of neutrophils and the hepatic failure in severe hepatitis patients.
