To determine whether an increase in the plasma concentration of uric acid by sucrose intake is ascribable to enhanced purine degradation and/or decreased urinary excretion of uric acid, we measured the plasma concentrations of purine bases (uric acid, hypoxanthine, and xanthine) and uridine, as well as the urinary excretion of purine bases in 7 healthy subjects before and after administering sucrose at 1.5 g/kg of body weight in 2 related experiments, with and without an administration of 300 mg of allopurinol. In addition, in the control experiment without an administration of sugar and with an administration of 300 mg of allopurinol, we measured the same parameters in those 7 subjects. Without added allopurinol, sucrose increased the plasma concentration of uric acid by 11% (P
