[Non-specific factors of defense in patients with various forms of acute pancreatitis]. 
In patients, suffering an acute pancreatitis with purulent-septic complications, there are observed: the blood neutrophils metabolic activity raising in spontaneous NST--test, the reserve index of the blood neutrophils metabolic activity is secured, but the phagocytic number is lowered, raised or normal.  In patients, who have died, the blood neutrophils metabolic activity in stimulated NST--test is raised, but preservation reserve of their metabolic activity is lowered, in comparison with such in a control group.  Trustworthy raising of the blood neutrophils metabolic activity in stimulated NST--test was observed in patients, suffering infected pancreonecrosis, in comparison with such in aseptic necrosis, the phagocytic number in them was trustworthy reduced.  In patients, suffering an acute pancreatitis, who have died, there was established the reversed correlation dependence between the formazanpositive blood neutrophils quantity in spontaneous NST--test and preservation reserve.
