对32例肝胆系统疾病的肝穿刺材料进行电镜观察,发现肝内增生的胶原纤维不仅存在于汇管区及Disse腔,也见于肝细胞内。肝细胞内的胶原绝大部分为胶原原纤维,其排列紊乱,混杂于肝细胞器之间,无界膜包裹,提示肝细胞内的胶原原纤维由肝细胞所产生。
Electron microscopy of liver biopsy material in 32 cases of hepatobiliary diseases revealed that intrahepatic collagen fibers not only exist in portal area and Disse cavity but also in hepatocytes. The vast majority of collagen within the liver cells collagen fibrils, arranged in disorder, mixed between the hepatic organelles, boundless membrane wrapped, suggesting that collagen fibers within the liver cells produced by the liver cells.
