光镜观察发现,翘嘴鲌(Culter alburnus)肝脏浆膜较薄,边缘肝细胞排列紧密,肝小叶不明显,肝血窦相互交织成网络状,可见枯否氏细胞,偶见双核肝细胞.肝实质中有极少量胰腺组织分布.肝内血管系统由小叶间静脉、小叶间动脉、肝血窦、中央静脉、支静脉和肝叶中央静脉组成,肝叶中央静脉特别发达,贯穿整条肝叶,管壁较薄,由内皮和结缔组织组成.胆管系统由胆小管、小叶内胆管、小叶间胆管、支胆管和肝叶中央胆管组成,其中支胆管和肝叶中央胆管特别发达,肝叶中央胆管与肝叶中央静脉伴行,管壁较厚,分为3层,内层由单层高柱状上皮和固有膜组成,中层由环形平滑肌组成,外层由结缔组织组成.电镜观察发现,翘嘴鲌肝细胞无明显的双态现象,常染色质充满整个细胞核,核仁大而明显.胞质中分布有丰富的核糖体和发达的内质网,线粒体特别丰富,内嵴发达,可见次级溶酶体和髓样小体,髓样小体周围有较多线粒体环绕,糖原颗粒丰富,但脂滴较少.肝细胞近狄氏间隙面和近胆小管面突起形成较多微绒毛,高尔基复合体靠近胆小管区域分布,说明肝细胞具有旺盛的吸收、合成和分泌能力.
Light microscopic observation showed that the liver membrane of Culter alburnus was thinner, the marginal hepatocytes arranged closely, the hepatic lobules were not obvious, and the hepatic sinusoids interwoven into network. The liver parenchyma has very few pancreatic tissue distribution.The intrahepatic vasculature consists of the interlobular vein, the interlobular artery, the hepatic sinusoid, the central vein, the branch vein and the central lobe of the hepatic lobe, the central lobe of the hepatic lobe is particularly well developed throughout the entire liver The leaf, the thin wall, consists of the endothelium and connective tissue.The bile duct system consists of the small bile duct, the small intrahepatic bile duct, the interlobular bile duct, the bile duct and the central lobe of the hepatic lobe, of which the bile duct and the central lobe of the liver are particularly well- Central leaf bile duct and the central lobe of liver accompanied by a thick wall, is divided into three layers, the inner layer of monolayer of high columnar epithelium and lamina propria, the middle by the smooth muscle composition, the outer layer of connective tissue.Electron microscopy findings , There is no obvious bimodal phenomenon in C. albiflorus hepatocytes, the chromatin is filled in the entire nucleus and the nucleoli are large and obvious.They are abundant in the cytoplasm and rich in endoplasmic reticulum, mitochondria are abundant, the inner crest is developed, Visible secondary lysozyme Body and medullary bodies, surrounded by medullary bodies more mitochondria, rich in glycogen particles, but lipid droplets less proximal liver cell gap and near the surface of the dilated cholecystitis to form more microvilli, Golgi Complex near the bile duct area distribution, indicating that hepatocytes with strong absorption, synthesis and secretion capacity.
