乙型肝炎病毒在肾病科通过血透析机、乙型肝炎病毒携带者和输血传播。从理论上讲,完整的病毒颗粒似乎不可能通过透析膜,因为透析膜的微孔直径仅30～90(?),而Dane颗粒(乙型肝炎病毒颗粒)是42nm。病毒的DNA或核壳可能是传染成分,然而至今尚未分离出这两种颗粒。本文作者观察到,在感染乙型肝炎病毒的血透析病人中,有20%在其使用不同血透析系统(HD)的透析超滤液中存在HBsAg。研究对象为一组30例血清HBsAg阳性 Hepatitis B virus is transmitted by hemodialysis machines, hepatitis B virus carriers and blood transfusions in the nephrology department. In theory, it seems unlikely that intact virus particles will pass through the dialysis membrane because the dialysis membrane has a micropore diameter of only 30-90 (?), While Dane particles (Hepatitis B virus particles) are 42nm. The virus DNA or nucleocapsid may be an infectious agent, however, these two types of particles have not been isolated so far. The authors observed that 20% of hemodialysis patients with hepatitis B virus present HBsAg in their dialysis ultrafiltrate using different hemodialysis systems (HD). The subjects were a group of 30 cases of HBsAg positive serum
