作者对药物或肝毒性物质所致的肝血管病变作了研究。与药物或毒物有关的肝血管损害可归纳为以下几方面:(1)肝静脉主干或小分支闭塞;(2)窦状隙扩张、肝紫斑病(显微镜下见肝小叶内血液郁滞,伴有肝坏死)、窦周纤维变性;(3)门脉及其分支的改变;(4)肝动脉系统的变化。肝血管病变与药物或毒物的关系见下表。 The authors studied hepatic vascular lesions caused by drugs or hepatotoxic substances. Hepatic vascular lesions associated with drugs or poisons can be summarized as follows: (1) occlusion of the trunk or small branches of the hepatic veins; (2) dilatation of the sinusoids, hepatic purpura (see hepatic lobule blood stasis in the microscope, Liver necrosis), sinus fibrosis; (3) portal vein and its branches change; (4) hepatic artery system changes. The relationship between hepatic vascular lesions and drugs or poisons is shown in the table below.
