1·Objective: To investigate the changes of the activities of urine brush border enzymes in lead exposed workers and their significances.

目的：探讨铅接触者尿绒毛膜酶活性的变化及其意义。

2·The little blue organisms lined up along the brush border of the small intestinal epithelium are Cryptosporidia. This infection causes diarrhea in immunocompromised hosts.

沿着小肠上皮刷状边缘排列的呈蓝色的病原体是隐孢子虫。隐孢子虫感染使免疫缺陷病人腹泻。

3·The enteropathy shown here has loss of crypts, increased mitotic activity, loss of brush border, and infiltration with lymphocytes and plasma cells (B-cells sensitized to gliaden).

这里显示这种肠病缺乏腺管、有丝分裂活跃、刷状缘消失，伴有淋巴细胞和浆细胞浸润（B细胞对麦胶敏感）。

4·The results of immunohistochemistry revealed that ASBT was expressed at brush border membrane of proximal renal tubular cells, but not expressed in distal tubule and renal interstitium.

免疫组化染色表明ASBT蛋白主要表达于人近端肾小管上皮的刷状缘侧，在间质及远端小管没有表达。

5·Conclusions Total small bowel resection caused significant adaptive expression of brush-border sucrase and maltase in the residual digestive tract in the rats after a total small bowel resection.

结论全小肠切除大鼠经肠内喂养后，其残留肠道黏膜细胞的可代偿性表达蔗糖酶和麦芽糖酶。
