| 摘 要： | 采用形态解剖、组织学及组织化学方法,分别用HE和AB-PAS染色法对驼背鲈(Cromileptes altivelis)的消化系统进行了研究。结果表明:驼背鲈食道内表面分布较多宽大的粘膜褶;胃分为贲门部、盲囊部和幽门部,贲门部胃小凹和胃腺最多,盲囊部厚度最大;前、中、后肠粘膜褶丰富,后肠粘液细胞密度最大;幽门与前肠交界处有幽门盲囊10~13个,结构与前肠相似。食道,胃,前、中、后肠及幽门盲囊均以分泌中性粘多糖的Ⅱ型粘液细胞为主。驼背鲈消化系统的结构表现出与其肉食性习性相适应的特点。

| Abstract: | The digestive system of Cromileptes altivelis was studied by dissection,histology and histochemistry with HE and AB-PAS dyeing.Results indicated that many broad mucosa pleats existed on the internal surface of oesophagus.The stomach was composed of cardiac portion,blind sac and pyloric portion,among which gastric pits and gastric gland in cardiac portion were the most in number and the blind sac was the thickest.There were abundant mucosa pleats on the surface of foregud,midgut and hidgut where the density ... |
