On high efficient Cation Exchange Resins, AmRIR IR 120 and AmR IRC 50 and Anion Exchange Resin AmRIR IR 4 which are now most widely used in Japan. I conducted experiments in vitro and in vivo to see if they will absorb amino-acid, the most important nutritive substance for a human body, when they are taken or whether or not they will be hindered from absorbed it.
As a result of the experiments, I knew part of basic amino-acids are absorbed and excreted by Cation Exchange Resins.
Furthermore administering H-type and NH
4-type of AmRIR 120 and AmR IRC 50 to rats, I observed these facts:
1) The rat's weight did not undergo a remarkable change and the urine increased in quantity.
2) The excretion of Na and K in the urine remarkably increased, while that of Na and K in the feces decreased.
3) The sum of excretion of Na and K in the feces and urine showed an increase in proportion to its contrast.
4) The excretion of N decreased in H-type and increased in NH
4-type.
