纹状缘

前肠粘膜褶高，纹状缘薄，杯状细胞数目相对乌鳢、鲶鱼较多。

Their fore-gut has high mucosal fold , thin striated border , more goblet cells .

绍鸭直肠也具有纹状缘等结构，且其生长速度相似于十二指肠，故推测也有吸收功能。

The rectum has the striated border , and its growth rate is found to be similar to those of the duodenum , suggesting its possible function of absorption .

柱状细胞的纹状缘PAS反应呈强阳性；

Strongly positive PAS reaction was shown in the striated horde of columnal cells .

结果和结论：制备得到的囊泡均匀圆整，粒径0.55±0.11μm，5-FU在纹状缘囊泡的摄取过程包含主动转运与至少一个顺浓度梯度的被动过程。

The uptake of 5-FU by BBMVs was determined by the fast filtration techniques . RESULTS AND CONCLUSION The vesicles were spherical particles with size of 0.55 ± 0.11 μ m. The uptake of 5-FU contained active transport and at least one concentration gradient-dependent passive process .

The reaction of the brush border and goblet cells in the lower half of villi in duodenum was stronger than that of upper half villi for lectin staining .

消化道上皮细胞有无纹状缘是区分中肠与前、后肠的重要标准之一。

The epithelium cells of digestive tube with or without the striated border can be used as one of important standard for distinguishing the midgut from foregut and hindgut .
