对脾功能亢进这个复杂现象还没有很好的解释。Banti 于1882年通过许多实验提出两种假说:①脾脏破坏大量血细胞;②脾内产生某些生化物质进入血循环而影响造血器官。Doan(1949)认为脾肿大后对红细胞的阻留作用增强,Janal 及Aster(1967)支持这种看法,而 Dameshek(1955)和 Rubenstroth-Bauer 等(1967)则认为脾脏能释放某种体液因素,这种体液因素抑制骨髓产生和释放血细胞,但直到目前尚未找出确切的体液因素。另一方面,某些原因引起脾肿大后,均能使牌内的网
The complex phenomenon of hypersplenism has not been well explained. Banti in 1882 through many experiments put forward two hypotheses: ① spleen damage a large number of blood cells; ② spleen produce certain biochemical substances into the blood circulation and affect the blood-forming organs. Doan (1949) argues that splenomegaly increases the retention of erythrocytes, and Janal and Aster (1967) support this view, whereas Dameshek (1955) and Rubenstroth-Bauer et al. (1967) argue that the spleen releases certain humoral factors This humoral agent inhibits bone marrow production and releases blood cells, but until now no exact humoral factors have been found. On the other hand, some causes splenomegaly, can make the net within the card
