  Background and Aim: Neutrophil elastase releasing from activated polymorphonuclear neutrophils (PMN) may have a central role in acute lung injury. Thus, we examined whether neutrophil elastase activity (NEA), a crucial parameter for organ damages from stresses, may increase in intra-operative recovered blood and also whether the storage duration of the bank bloods may affect such changes in NEA. Methods: In thirty-two packed red cells of bank bloods, NEAs were measured by ELISA on several day points after the storage. Intra-operative salvaged red cell concentrates (RCCs) were obtained from thirteen patients undergoing spinal surgery. The salvaged bloods from the patients were divided into two groups: NE activities in autologous RCCs obtained from eight patients were examined soon after the preparation (Group A); such activities in RCCs from five subjects were determined post-operative..
