经电镜检查发现，乙型肝炎病人外周血中性粒细胞存在形态学和超微结构的异常改变。其异常包括粒细胞的形态不规则、多伪足和吞噬空泡、核体密度增加、比表面变小、颗粒减少以及粒细胞出现崩解、核孔和核泡等。本文为乙型肝炎病人粒细胞功能异常提供了形态学上的证据 Electron microscopic examination revealed abnormal changes in the morphology and ultrastructure of peripheral blood neutrophils in hepatitis B patients. Its abnormalities include the irregular shape, irregular pseudopods and phagocytosis of granulocytes, the increase of density of nucleosomes, the decrease of specific surface area, the reduction of granules, the disintegration of granulocytes and the appearance of nuclear pores and vesicles. This article provides morphological evidence for the abnormal function of granulocytes in hepatitis B patients
