epithelial duct

Capillaries were no expansion and no inflammatory reaction . Cells were simple columnar . Epithelial and duct were clear boundaries .

细胞呈单层柱状，腺上皮和腺管分界清楚。

The structure and epithelial appearance of duct and gland alveolus do not have much difference .

各分区的导管、腺泡的结构和上皮形状差别不大。

However , the peak time of ETB mRNA receptor was at 6 hour and mainly localized on renal medullary tubule epithelial and collecting duct cells .

ETB受体mRNA于再灌流6小时达高峰，主要分布髓质肾小管、集合管。

The effect of apoptosis in biliary epithelial cells on bile duct hyperplasia in jaundiced rat liver

梗阻性黄疸肝内增生胆管上皮细胞凋亡的实验研究

[ background ] Primary liver cancer ( PLC ) is malignant tumor primary at hepatocyte or epithelial cells of bile duct .

[背景]：原发性肝癌（PLC）指原发于肝细胞或胆管上皮细胞的恶性肿瘤，属于中医的臌胀、肝积、症瘕、积聚、黄疸、胁痛、暴症等病范畴。

Conclusions : Bcl2 protein may take effect on the canceration stage of the pancreas cells and is related with the epithelial canceration of pancreas duct .

结论：bcl2蛋白可能作用于胰腺细胞的癌变阶段，并与胰腺导管上皮癌变有关；

The neoplastic epithelial cells within the duct show minimal hyperchromatism and pleomorphism , but they have holes with sharp margins as though punched out by a cookie cutter .

导管内的肿瘤上皮细胞显示出轻微的着色过深与多形性，但它们的空洞边缘锐利就好象是用小甜点切割刀切成的一样。

RESULTS : Histochemically , in normal rats , the NOS positive staining was found in epithelial cells of respiratory duct including bronchi , alveolar duct as well as in endothelium of pulmonary vessels , and the negative staining was found in pneumonocytes .

结果：组织学上显示，对照组大鼠呼吸道包括支气管、细支气管、终末细支气管、肺泡管的上皮细胞和血管内皮细胞NOS表达均阳性，肺泡上皮细胞NOS表达阴性；

As shown by tissue sections , it was found that the trophozoites were first obtained in the epithelial cells of bile duct 3 days after infection , and the schizonts had been seen at the 6th day , but the peak number occurred in 13 days after infection .

切片中显示，感染3天后小胆管上皮细胞中有滋养体。第6天开始有裂体生殖，第13天达高峰。
