The use of polyethylene glycol 4000 as a non-absorbable, continuously fed faecal marker is described. The intestinal handling and transit of polyethylene glycol is compared with that of chromium sesquioxide and barium sulphate. Polyethylene glycol is an acceptable non-absorbable faecal marker for calcium, phosphorus, and fatty acids, and has several features which commend its use in preference to insoluble chromium sesquioxide and barium sulphate particularly when marking water-soluble dietary constituents.
描述了使用聚乙二醇 4000 作为不可吸收的连续喂养粪便标志物。比较了聚乙二醇与三氧化二铬和硫酸钡的肠道处理和转运。聚乙二醇是一种可接受的不可吸收的粪便钙、磷和脂肪酸标志物,并且具有一些特点,使其优于不溶性三氧化二铬和硫酸钡,特别是在标记水溶性膳食成分时。
