title: [Amino acid kinetics during hemodialysis].
abstract: The kinetic of essential amino acids as well as of histidine and alanine in bilateral nephrectomized rabbits was investigated during a 3 hours hemodialysis. Dialysis, elimination and incorporation rates into plasma proteins were determined for all applied amino acids. Total elimination rates of all the investigated amino acids varied. From 5.31% (leucine) to 75.51% (alanine) of the injected labelled amino acids were eliminated in the dialysate. There was an exponential decrease in the dialysis of essential amino acids and histidine during the period of investigation due to the high incorporation rate into plasma proteins. The kinetic of alanine was different due to a slow incorporation rate leading to a higher elimination rate. The fast incorporation of intravenously applied essential amino acids and histidine during dialysis demonstrates that the existing protein deficiency in renal failure can be influenced positively by infusion of amino acids.
