中肠腺

中肠腺小管上皮在Z2期细胞已有了分化，由4类细胞组成，即胚细胞（E细胞）、纤维细胞（F细胞）、泡状细胞（B细胞）和吸收细胞（R细胞）。

The midgut gland cell differentiation occurs at Z2 . There are 4 types of cells , i. e. , embryonic cell ( E-cell ), fibrillar cell ( F-cell ), blister cell ( B-cell ) and resorptive cell ( R-cell ) .

日本对虾中肠腺坏死杆状病毒病的组织细胞病理研究

Preliminary Study on Histopathology of Midgut Gland Necrosis Baculovirus in Penaeus japonicus

在幼体发育初期，蛋白酶就具有活力，在N（3～4）、N（5～6）时期各个酶活力均有较大幅度的增长，这与中肠腺的分化程度有关。

At the early stage of larval development , protease kept high activities . Each of enzymes increased greatly in the stage of N_ ( 3 ~ 4 ) and N_ ( 5 ~ 6 ), which was associated with liver differentiation .

利用组织切片法研究了斑节对虾杆状病毒（MBV）在养殖早期斑节对虾及养成期斑节对虾中肠腺各部位的分布特点。

The distribution of Penaeus monodon baculovirus ( MBV ) in different parts of mid gut gland in juvenile and adult shrimp Penaeus monodon was studied by light microscopy .

其中，前肠由口、食道、胃等组成；中肠有中肠前盲囊和中肠腺等附属结构。

Both anterior midgut caecum and midgut gland are appendant organs of the midgut .

中肠腺是蛋白酶的主要分泌器官，淀粉酶在不同消化组织没有显著差异。

In different digestive tissues , the highest protease activity was found in the midgut gland .
