本文收集胎儿肝脏41例用 Unna 氏法显示 RNA,PAS 法显示糖原,Gomori 氏钙钴法显示 ALP 及 Altamann 氏法显示线粒体。7周胚的肝脏已出现交织成网的肝细胞索和大量血窦,8周出现少量结缔组织围于门静脉分支的周围,9～12周逐渐形成肝小叶和门管区,门管周围界板细胞9周已形成小叶内和小叶间胆管。8周胚肝细胞排列成板,肝板的厚薄常随血窦大小而变化,说明肝板的可塑性。胚胎期肝细胞内富含 RNA、糖原和线粒体,而 AlP 活性较弱。胚胎期肝小叶无明显的分带现象。
In this paper, 41 cases of fetus liver were collected using Unna’s method for RNA, PAS method for glycogen, Gomori calcium method for ALP and Altamann’s method to display mitochondria. Seven weeks embryo liver has emerged intertwined hepatocellular cord and a large number of sinusoids, 8 weeks a small amount of connective tissue around the branches of the portal vein around 9 to 12 weeks gradually formed hepatic lobules and portal area around the portal dendritic cells 9 weeks has formed lobular and interlobular bile duct. 8 weeks embryonic liver cells arranged in a plate, often with the thickness of the liver plate sinusoidal size changes, indicating the plasticity of the liver plate. Embryonic liver cells are rich in RNA, glycogen and mitochondria, and AlP activity is weak. Embryonic hepatic lobule no obvious zonation.
