[Application of a mathematical model to the penetration of amino acids through a dialysis membrane in chronic hemodialysis].

With the help of a one-pool-model from the clearance values measured for 4 different dialysator models the elimination rates for amino acids are calculated with special regard to the essential amino acids. In these cases the body-weight of the patient also belongs to the calculation of the elimination of the amino acids. The loss of the amino acids under the dialysis procedes corresponding to an e-function and is particularly high during the first period of dialysis.
