High ammonia concentration of blood was seen ingiving L-asparaginase and L-arginine. So that the necessary equipment to eliminate ammonia was needed. On account of high rapid elimination of ammonia electro-dialyser was used. The menbranes of CMV and AMV as electrodialyser were used and electrified between them. Electro-dialyser to use ultrafiltration has high point of rimiting current density. So that the effects on electro-dialyser were quantitatively analysed in vivo experiments. With increasing electrical current, the rapidity and efficiency of blood ammonia removal was increased. With maintaing acid base equilibrium, electrolyte (Na, K and ci) and osmotic pressure, ammonia was eliminated rapidly.
