Preparation of a new enzyme electrode for urea is reported , which is based on the ph glassy electrode modified with 2 - aminoethyltrimethoxysilane in advance , followed by the surface of the electrode being alternatitively crosslinked with glutaraldehyde and urease 摘要2 -氨基乙基三甲氧基矽烷在平板玻璃电极表面形成带氨基尾声端的单层，并与戊二醛和尿素酶交替交联制成对尿素有电位响应的电极。
4 forty - eight volunteers had two " jumbo " biopsies taken from the gastric antrum for examination with rapid urease test , improved giernsa stains and h & e in order to diagnose helicobacter pylori ( hp ) infection and evaluate inflammation of gastric mucosa 448例志愿者均行胃镜检查，取胃窦组织活检，分别行快速尿素酶试验、改良giemsa染色和病理he染色，以确定有无幽门螺杆菌( helicobacterpylori ， hp )感染和胃黏膜有无慢性炎症。
In contrast , in control gerbils or gerbils were unsuccessfully challenged , neither h . pylori nor other urease - positive organisms could be cultured from the gastroduodenal mucosa , rut results were consistently negative , and no serum antibodies to h . pylori whole - cell sonicates were detected Pylori快速尿素酶检测、血清学抗h pyloriigg抗体检测和特异性pcr检测，结果表明h pylori感染组动物以上各项指标均为阳性，表明已经感染h
