title: [Influence of parenteral fructose or glucose administration on uric acid formation and phosphate uptake of the human liver].
abstract: 15 min. after intravenous administration of fructose (10 g/5 min, 0,5 g/kg/h) the hepatic uric acid production in healthy volunteers increased from 0,07 mg/100 g X min to 0,52 mg/100 g X min. After one hour the enhanced uric acid production was 0,3 mg 100 g X min. The enhanced uric acid production was accompanied by an increased hepatic phosphate uptake. The highest value was 13 mumol/100 g X min. During the control period the liver released small amounts of phosphate into the hepatic vein. The increased hepatic uric acid output correlated with an enhanced renal clearance, therefore the peripheral venous uric acid concentrations remained unchanged.
