众所周知,白细胞具有吞噬作用,其在防预细菌或真菌的感染中起着极其重要的作用。具有这种吞噬作用的细胞有中性白细胞、单核细胞、嗜伊红细胞和嗜(齿佥)性白细胞,而淋巴细胞、血小板和红血球则无这种作用。粒系在骨髓发育过程中仅在中幼粒细胞发展到晚幼粒细胞阶段才获得吞噬能力,最大的吞噬效力是在多形核中性白细胞阶段。因而可
It is well-known that leukocytes have phagocytosis which plays an extremely important role in preventing infection by pre-bacteria or fungi. Cells with this phagocytosis have neutrophils, monocytes, eosinophils and addicted (lentigo) leukocytes, whereas lymphocytes, platelets, and red blood cells do not. Granulogenesis in phagocytic development only in the development of late promyelocytic neutrophil phase phagocytic ability was obtained, the largest phagocytic efficiency in polymorphonuclear neutrophils stage. Thus can
