伤寒是由伤寒杆菌引起的急性传染病，主要累及全身单核一巨噬细胞系统增生性反应，因而必然出现骨髓组织细胞增生及形态学变化。我们观察到在伤寒骨髓中有两类组织细胞显著增生，一类为戒指样组织细胞，一类为噬血组织细胞。由于戒指样组织细胞比噬血组织细胞对于诊断伤寒更具 Typhoid fever is caused by Salmonella typhi acute infectious diseases, mainly involving the systemic monocyte-macrophage system proliferative response, which inevitably occur bone marrow cell proliferation and morphological changes. We observed two types of tissue cells in the bone marrow of the typhoid fever were significantly hyperplasia, one for the ring-like tissue cells, one for the hemophagocytic cells. Because ring-like tissue cells than hemophagocytic cells for the diagnosis of typhoid even more
