title: [The use of urinary nitrogen indices for the evaluation and prognosis of protein nutrition in man].
abstract: In a group of similar subjects correlation has been revealed between the level of protein intake and nitrogen indices of urine assayed in the portion of urine taken on an empty stomach. The nitrogen indices of urine: creatinine N/total N, creatinine N/urea N, creatinine N/amine N, urea N/total N proved to be the most informative criteria of protein nutrition. It was found that the indices studied could be used as signs of providing the group of subjects with protein and for prognosing the protein nutrition level by the simulation of linear regression, using the methods of the random process theory.
