日本京都府立大学内科通过电子显微镜观察以及动物实验查明饮酒过多在肝中沉着脂肪,引起脂肪肝的机制。他们发现酒精能使肝脏毛细血管壁孔扩大,血中脂肪从这些孔洞渗入到肝组织内,引起脂肪肝。将白鼠分成甲乙两组,每组12只,甲组每日喂掺有酒精的饲料,经8周后,发生脂肪肝。然后通过电子显微镜详细观察对比,发现甲组脂肪肝鼠的肝脏中心静脉毛细血管壁上的微小孔洞直径平均达万分之1.04毫米,而乙组鼠(不喂掺有酒精的饲料)却只有万
Kyoto prefecture, Japan, Department of Internal Medicine by electron microscopy and animal experiments to identify excessive drinking excessive fat in the liver, causing fatty liver mechanism. They found that alcohol can enlarge the wall of the liver capillaries, blood fat from these holes into the liver tissue, causing fatty liver. The rats were divided into two groups A and B, each group of 12, Group A daily feed mixed with alcohol, after 8 weeks, fatty liver occurred. Then through the electron microscope detailed observation and comparison, found in fatty liver disease group A hepatic vein capillary wall diameter of tiny holes on average 1.04 mm, and group B rats (not fed with alcohol feed) but only
