在炎症活动期,中性白细胞、巨噬细胞等能产生氧自由基,并刺激脂类过氧化作用导致戊烷的产生。测定呼气中戊烷含量是反映器官炎症的非侵入性技术。本文旨在评估呼气中戊烷的测定及确定在炎症性肠病中的作用,并与~(111)In-粒细胞扫描作对照比较。 材料与方法:所选患者为已确诊的、或有症状而疑为IBD者。用~(111)In-粒细胞扫描影像判断受试者的炎症
In the inflammatory phase, neutrophils, macrophages and other can produce oxygen free radicals, and stimulate lipid peroxidation leading to pentane production. Determining pentane levels in exhaled breath is a non-invasive technique that reflects the inflammation of the organ. The purpose of this article is to evaluate pentane determination in exhaled breath and to determine its role in inflammatory bowel disease and to compare with ~ (111) In-granulocyte scan. MATERIALS AND METHODS: Selected patients were confirmed or suspected of having IBD. Subjects were assessed for inflammation using ~ (111) In-granulogram
