medicine. SUBSTANCE: method involves assay of riboflavin index value determining by dividing indices of activity of riboflavin-dependent enzyme glutathione reductase expressed as mcmoles of NADPH2/ml of erythrocytes/h on FAD-effect value in conventional units. Decrease of providing with vitamin B2, apparent hypovitaminosis and an adequate providing of body with riboflavin are determined in riboflavin index values 26.16-29.40; 26.15 or less and 29.41 conventional units, respectively. EFFECT: enhanced precision of assay. 1 cl, 3 ex |
