In this study, we determined the purine contents in milk and soymilk, as protein-rich drinks, and in enteral nutritional supplements employed to ameliorate protein malnutrition in the elderly. Milk consumption is known to lower serum uric acid levels and to promote uric acid excretion. However, discrepant results have been reported regarding the effect of soymilk on serum uric acid levels. The purpose of this study was to quantify and compare the total purine contents and the contents of individual purines and pyrimidines by molecular type (nucleotides, nucleosides, and bases).
在本研究中，我们测定了作为富含蛋白质饮品的牛奶和豆浆以及用于改善老年人蛋白质营养不良的肠内营养补充剂中的嘌呤含量。众所周知，饮用牛奶可降低血清尿酸水平并促进尿酸排泄。然而，关于豆浆对血清尿酸水平的影响，已有相互矛盾的报道。本研究的目的是按分子类型（核苷酸、核苷和碱基）对总嘌呤含量以及单个嘌呤和嘧啶的含量进行定量和比较。
