measurements of renal tissue aib in these experiments revealed that cellular aib is of sufficient magnitude and bears such a relationship to plasma aib and feaib that it could contribute to an observable cell-to-lumen movement of amino acid in the `` '' pre-steady-state '' '' situation and could account for the rise in feaib following aib infusion and the collapse in tubular reabsorption of aib at 2 -- 4 mm plasma [ aib ] .
