| 摘 要： | 采用常规解剖、石蜡切片、苏木精-曙红染色（hematoxylin-eosin, H-E）和显微摄像等组织学研究技术，研究杂食性鲤鱼和肉食性花鲈肝脏的解剖与组织结构，并对其进行较为详细的比较。结果表明：2种鱼肝脏的形态、大小、色泽、致密度及胆囊状况等均有区别；组织结构上2种鱼肝脏均外被薄层浆膜，切片上由于伸入肝实质内结缔组织较少，很难区分为肝小叶结构。中央静脉形状多变，且分布不规则。小叶周缘门管区有小叶间动脉血管、小叶间静脉血管和小叶间胆管分布。胰脏外分泌组织包于肝组织之内，沿门静脉分枝周围分布，构成肝胰脏，与肝组织有薄层结缔组织界膜分开。肝胰脏主要由腺泡构成，腺泡内有泡心细胞。鲤鱼肝胰脏较发达，所含腺泡较多，腺细胞主要含有大量嗜酸性的酶原颗粒，少量腺细胞核致密，胞质被H-E染为桔黄色；花鲈肝胰脏较少，腺细胞亦含大量嗜酸性的酶原颗粒，在肝胰脏附近分布有大量黑色素巨噬细胞集合体，而鲤鱼肝脏中未观察到类似组织结构。 |

| Abstract： | Routine anatomy, paraffin section, hematoxylin-eosin (H-E) staining and micrography histology research techniques were used to study the liver structure of Cyprinus carpio (omnivorous) and Lateolabrax japonicus (carnivorous) and much detail comparative work was done to understand the relationship between structure and function. The results showed that there were differences between the two kinds of liver on size, shape, volume, color, density and the state of gallbladder on tissue structure, and the livers were both covered by thin serosa layer. Light-microscope observation showed that it was not possible to distinguish hepatic lobule for less connective tissue enters hepatic parenchyma from serosa layer. Central veins were found varied in size and randomly throughout the hepatic parenchyma of fish, irregularly. There were interlobular arteries, interlobular veins, and interlobular bile ducts distributed at portal area around hepatic lobule. Exocrine pancreatic tissue located in the liver, around the major portal vessels and was collectively called the hepatopancreas. Thin septa of connective tissue separated the hepatocytes from the exocrine pancreatic cells. Hepatopancreas were mainly formed by acinus with centro-alveolar cells. Hepatopancreas developed well in liver of C. carpio, which had more acinus, the gland cells contained numerous acidophilic zymogen granules, a few glands were with compact nucleolus, which cytoplasm stained saffron by H-E. Hepatopancreas of L. japonicus developed poorly, only a few acinus, the gland cells also contained numerous acidophilic zymogen granules. Along portal vein and its branches there were numerous melano-macrophage aggregates in liver of L. japonicus beside its hepatopancreas, but none of that kind of structure was found in liver of C. carpio. |
