[Changes in immunologic reactivity in patients with gastrointestinal bleeding].

The disorders in immunologic reactivity in acute gastrointestinal bleeding were studied in dynamics in 160 patients. Pronouncement of disorders in the T-system of immunity, activation of the reactions of specific sensibilization and autoallergic phenomena depend on severity of the blood loss. In ulcer location in the duodenum, the performance of an organ-preserving operation with vagotomy and elimination of the ulcer which is a source of antigen stimulation is preferable.
