摘要: 介绍了用１３Ｃ－三辛酸甘油酯为标记药物通过呼气实验诊断脂肪代谢疾病的方法，进而引出了用稳定同位素标记的类似药物来诊断同样疾病的研究．结果指出，两种方法是等效的，由于稳定同位素对人体无害，因而后者更有应用前景.The experiment in which 13 C trioctanoin was used as a labeled substrate to diagnose the disease about fat malabsorption was explained and followed by a research on the diagnosis of the same disease with 13 C substrate. Both of the experiments proved effective, moreover the latter would be better since the stable isotope is harmless.
