THE PHENOTYPE AND METABOLISM RELATIONSHIP OF BLOOD NEUTROPHILS IN PATIENTS WITH WIDESPREAD PURULENT PERITONITIS IN THE POSTOPERATIVE PERIOD DYNAMICS
The aim of the study was to examine the relationship of the phenotype and metabolism of neutrophils in patients with widespread purulent peritonitis (WPP) in the dynamics of the postoperative period. The study involved 27 patients with acute surgical diseases and injuries of abdominal organs complic...
