通过石蜡包埋切片及HE染色法对幼鱤的咽、肠与肝胰脏进行了较系统的组织切片观察。结果表明：幼鳡的肠道结构由内至外分别为绒毛、黏膜层、黏膜下层、肌肉层、浆膜层,在黏膜下层中存在横褶皱,中肠褶皱较少;肝、胰脏未发生明显分化,其上分布有血窦及胆小管,细胞间隙小、排列紧密,相连成为肝板;咽组织结构松散,由粘膜层、肌肉层、浆膜层组成,有粘膜皱褶。结构表明消化系统结构与生长特征的一致性。探明鳡幼体阶段发育特征,为其人工养殖提供必要的参考资料。

By the paraffin embedded sections and HE staining we have a relatively histological observation on the digestive system.The results showed that： the intestinal structure of young bambusa from the inside to the outside were fluff,mucosa,submucosa,muscle layer,serosa.the cross-fold exists in the submucosa,Midguthave less Fold than the other two;liver and pancreas does not occur clear differentiation,there are sinusoids and bile duct in it;cell gap is small,and they are closely arranged,form a hepatic plate;pharyngeal is a loose structure,and con...
