[Subacute citrullinemia--diagnosis and course up to 4th year of life].

The article reports on an infant which first in age of nine months and then again in age of 1.6 years had an episode of stupor. Laboratory investigation showed hyperammonemia and high values of transaminases.

[Excretion of normal and modified RNA catabolites and creatinine in the urine as a function of nutrition in children].

The urinary excretion of 5 modified and 2 unmodified RNA catabolites and of creatinine has been investigated in two children aged 71/2 and 6 years under different isocaloric diets over 5 days each (phase I-III) and compared with the excretion values during a 12-day and libitum food intake (phase 0). On a diet (phase I) extremely rich in nucleic acids (meat) there is only a slight increase of the modified RNA catabolites and a pronounced increase of creatinine in urine. On a protein-rich diet free from nucleic acids (phase II) the urinary RNA catabolites largely parallel the values seen under ad libitum food intake.
