[The influence of food-supply to the concentration of blood ammonia (author's transl)].

It has been determined of 70 liver-healthy probands the ammonia concentration of capillary blood after poor on protein respectively rich on proteine food in 30 minutes distances. It comes in both groups to a spontaneous ascent the concentration of ammonia. The highest ammonia concentration depends on the content of protein which has been taken through food and the descent also variable quick. For it amount to the waiting period of food on the determination of blood ammonia after in frontly poor on protein food 90 minutes and after in frontly rich on protein food three hours. The statements have been secured statisticaly by means of U-test.
