title: [Nitrogen metabolism in various forms of protein-vitamin deficiency].
abstract: Experiments were made on rats to study the effect of protein deficiency, amino acid unbalance and vitamin B1, A, E, C deficiency on the weight gain of rats, on the eating up of feed, the blood content of nitrogenous components and their excretion with urine and feces. The feeding of the diets deficient in protein, essential amino acids and vitamins leads to substantial changes in nitrogenous metabolism. Such alimentary disorders are followed by the reduced assimilability and biological value of food proteins.
