[Nonspecific immunity indices in acute gastrointestinal hemorrhage of peptic etiology].

The state of phagocytic activity of neutrophils, phagocytic index, opsonic coefficient, activity of blood serum lysozyme were studied with acute gastro-intestinal hemorrhages (ulcerous etiology in 116 patients, non-ulcerous etiology in 76 patients). The dependence of reduction of indices of phagocytosis and blood serum lysozyme on the degree of blood loss and duration of the posthemorrhagic period was revealed which may be used in clinical practice.
