Xylose absorption tests were performed on patients unselected except to exclude gastrointestinal or renal disease. The proportion of xylose excreted decreases with increasing age. Intravenous xylose tests suggest that this is due to a deterioration in renal function rather than to a reduction in intestinal absorption.
除排除胃肠道或肾脏疾病外,未对患者进行筛选就开展了木糖吸收试验。随着年龄增长,木糖排泄比例降低。静脉注射木糖试验表明,这是由于肾功能恶化而非肠道吸收减少所致。
