title: [Evaluation of blood loss volume and the degree of activity of nonspecific ulcerative colitis by using Cr51-labeled erythrocytes].
abstract: The volume of daily blood loss was studied in 47 patients with nonspecific ulcerative colitis by labelling red cells with radioactive sodium chromate. The volume of blood loss correlated closely with the activity of the inflammatory process evaluated during colonoscopy. Unlike visual, often erroneous, evaluation of blood loss, radioisotope study in dynamics makes it possible to objectify the appraisal of the activity and severity of the process, choose a rational therapeutic tactics, and determine the efficacy of the antiinflammatory treatment.
