a comparison of plasma concentrations of amino acids measured by chromatography before and after 113 periods of haemodialysis in 23 patients showed significant decrease in aromatic amino acids ( p less than 0.001 ) , a significant increase in two branched-chain amino acids : leucine ( p less than 0.001 ) and isoleucine ( p less than 0.001 ) , and a significant increase in fischer 's ratio ( p less than 0.001 ) .
