[Cellular factors of natural immunity in patients with acute peritonitis].

A total of 233 patients with acute peritonitis who in the postoperative period were subjected only to conventional complex intensive care (Group I) have been examined. Changes in medium molecular weight polypeptide level, relative and absolute monocyte and granulocyte content, phagocyte number and index, blood phagocytosis capacity and metabolic potential of macrophages in spontaneous and activated NBT test have been established. Integral tetrazolium neutrophil activity was different in subgroups of patients with (Group I) and without (Group II) complications. The factors which play the key role in the formation of pyoseptic complications have been identified as were diagnostic-prognostic tests evaluating their critical level. Patients from Group II with a high level of medium molecular weight toxin, besides conventional therapy, were subjected to hemosorption which brought about a positive clinical and laboratory effect.
