迁延性慢性腹泻病患儿回肠末端纹状缘肽酶及双糖酶活性的初步研究

目的测定迁延性慢性(迁慢性)腹泻病患儿回肠末端纹状缘肽酶及双糖酶活性水平,探讨回肠末端黏膜组织学形态与纹状缘肽酶、双糖酶活性水平的关系。方法收集结肠镜检查患儿回肠末端黏膜标本行病理学检查,以迁慢性腹泻病及非腹泻病组患儿为观察对象,两组中病理学检查为慢性炎症者为慢性炎症组,余为黏膜正常组。非腹泻病组中病理学检查结果正常者为对照组,测定回肠末端黏膜标本中纹状缘肽酶和双糖酶活性水平。结果2007年7月至2008年3月在广州医学院附属广州市儿童医院共收集到27例回肠黏膜标本,光镜下见其绒毛形态均正常,病理学检查10/27(37.0%)例有慢性炎症。迁慢性腹泻病组纹状缘肽酶及双糖酶活性水平与对照组差异均无统计学意义(P>0.05),慢性炎症组纹状缘肽酶及双糖酶活性水平与黏膜正常组差异均无统计学意义(P>0.05)。结论回肠末端黏膜绒毛正常的迁慢性腹泻病患儿,其纹状缘肽酶及双糖酶活性水平无明显变化。慢性炎症且绒毛正常的回肠末端黏膜,其纹状缘肽酶活性及双糖酶无明显变化。

Preliminary study on the activities of terminal ileum mucosal brush border peptidase and disaccharidase in children with persistent diarrhea and chronic diarrhea

Objective To investigate the changes of terminal ileum brush border peptidase and disaccharidase activities in persistent diarrhea and chronic diarrhea children.To investigate the relationship between ileum mucosal histology and the ileal brush border peptidase and disaccharidase activities.Methods The terminal ileal mucosal specimens were collected from children who were taken enteroscopy during July 2007 to March 2008 in our hospital.Two ileal mucosal specimens were obtained from the terminal ileum endosc...
