幽门囊

幽门盲囊蛋白酶活力摄食后开始降低，而从摄食后4h开始升高（P<0.05）；

That of protease in pyloric caeca lowered at the beginning of feeding , and raised 4h after feeding ( P < 0.05 );

淀粉酶活性大小顺序为：肝脏>幽门盲囊>胃>肠；

The amylase activity sequence was liver > pyloric caeca > stomach > intestine ;

幽门盲囊每排54&82个、肝为网管腺。

Every range of pyloric caeca is 54 to 82 . Liver is reticulo tubular gland .

其脂肪酶活性大小由高到低的顺序为：肠道胃肝脏幽门盲囊。

And the intestine tract had the highest activity of lipase activity , followed in sequence by stomach , liver and pylorus .

裂体生殖和配子生殖发生在幽门盲囊和前肠上皮细胞核之上方。

Both schizogony and gametogony occur at the place above the nucleus of the epithelia cells of pyloric caeca and anterior intestine .

幽门盲囊组织学特征与肠道相似，上皮为柱状上皮，其中的杯状细胞少于肠道。

The histological features of pyloric caeca were similar to those of small intestine , with columnar epithelium and less goblet cells .

胃与肠相接处有8～9个指状幽门盲囊，其形态学和组织学特征与前肠类似；

There were 8-9 pyloric caeca at the joint of the stomach and intestine , of which the morphologic and histological characters were similar to the cranial intestine 's.

第24天和第48天，在同一盐度下，各消化器官蛋白酶活力和淀粉酶活力高低顺序依次均为：幽门盲囊、肠道、胃和肝脏；

On the24th and48th day , at the same salinity , the protease and amylase activity in descending order were as follows : pyloric caeca , intestine , stomach and liver ;

在0M-0.5M的盐度变化范围内，幽门盲囊蛋白酶、肠蛋白酶随盐度增高被激活，胃蛋白酶、脂肪酶和淀粉酶均先被激活后被抑制。

At salt concentration range of OM-0.5M , the activity of proteases in pylorus cecum and gut of turbot are activated when the salt concentration is increased . And the activity of stomach protease is activated in low salt concentration but inhibited in high salt concentration .
