[The characteristics of nitrogen metabolism in the tissues of rabbits with ammonium toxicosis].
Disturbances of nitrogen metabolism under acute ammonium toxicosis have been studied in tissues of rabbit. A sharp increase of the ammonium content in the blood and tissues of the liver and kidneys is accompanied by an increase in the glutamine and glutamate level in all tissues. The level of urea nitrogen in the blood of rabbits increases. The activity of phosphate-independent and phosphate-activated glutaminase also increases in tissues of the liver and kidneys, while arginase activity decreases as compared with the control, which is connected with fall of the ATP level under hyperammonemia. A nomograph method of representation of the redox state has been used.
