摘要
应用光学显微技术对大菱鲆(Scophthalmus maximus)心脏、胃、肠、肝脏、胰脏、脾脏、肾脏的结构进行了组织学观察。结果显示,大菱鲆的心脏分为心内膜、心肌层和心外膜,其中以心肌层为最厚。胃、肠的管壁由内向外分为:黏膜层、黏膜下层、肌层和浆膜。胃腺内偶见含有嗜酸性颗粒的细胞。肠皱襞较高,黏膜上皮为单层柱状上皮,杯状细胞散在于柱状上皮细胞之间。肝细胞体积较大,呈多边形,肝细胞以中央静脉为中心,排列成凹凸不平的肝细胞索,相邻的肝细胞索互相吻合连接成网状。胰脏大部分附着于肠壁上,少部分埋藏在肝脏内。脾脏实质分为白髓和红髓,中央动脉数量较多。肾脏无皮质髓质之分,由肾小体和肾小管构成。
The structure of heart, stomach, intestine, liver, pancreas, spleen, nephras in Scophthalmus maximus were observed with micro-technique. The results showed that there were three layers from inter to outer in the heart： endocardium, myocardium and epicardium, in which myocardium were the thickest. The dissepiment of stomach in which intestine included mucous layer, tunica submucosa, lamina muscularis mucosae and membrana externa. Sometimes oxyphilous particles were observed in stomach gland. The plicae of intestinal mucosa was simple ciliated columnar epithelium. Calyciform cell was found in the cellula columnoepithelialis and the volume was large. The volume of liver cells was so large and was polygon in shape. The liver cells made of concavo-convex liver cell cords with central vein as center. Most part of pancreas attached on the intestine wall while a few parts imbed in the liver. The splenic parenchyma was made up of white pulp and red pulp. There were many central arteriae inside the splenic parenchyma. Nephros were made up of renal corpuscle and renal tubule. Cortex and medulla was mixed together.
