采用形态观察与连续组织切片技术,观察和研究了哲罗鱼(Hucho tai men)肝脏和胰脏在胚胎期(水温7~8℃)和胚后期(水温3~14℃)的发育。结果表明,与大多数硬骨鱼类不同,哲罗鱼的肝脏是在破膜前就开始发生、发育,而胰脏是在破膜后出现,以后逐渐发育完善。受精18 d肝原基细胞出现,破膜8 d,胰细胞出现,破膜8 d肝后部开始贮存脂质,破膜18 d后肝前部开始积累脂质,肝脏发育与卵黄囊有密切的关系。肝脏和胰脏为相互分开的独立器官,具有丰富的肝、胰管。
採用形態觀察與連續組織切片技術,觀察和研究瞭哲囉魚(Hucho tai men)肝髒和胰髒在胚胎期(水溫7~8℃)和胚後期(水溫3~14℃)的髮育。結果錶明,與大多數硬骨魚類不同,哲囉魚的肝髒是在破膜前就開始髮生、髮育,而胰髒是在破膜後齣現,以後逐漸髮育完善。受精18 d肝原基細胞齣現,破膜8 d,胰細胞齣現,破膜8 d肝後部開始貯存脂質,破膜18 d後肝前部開始積纍脂質,肝髒髮育與卵黃囊有密切的關繫。肝髒和胰髒為相互分開的獨立器官,具有豐富的肝、胰管。

The histological and morphological ontogenesis of liver and pancreas in taimen Hucho taimen was studied by serial section technique.The results showed that there are significant differences in the taimen from most of the teleost in that the liver ontogenesis initiated before hatching in the taimen and the pancreas ontogenesis was appeared after hatching.The liver primodium was observed 18 days after fertilization,and the pancreatic cells were found 8 d after hatching,and the liver cells to have fat storing 18 days after hatching,indicating that the liver development is involved in yolk absorption.The liver and pancreas are independent organs,and have prolific tubes.
