Upregulation of reactive oxygen species generation and phagocytosis, and increased apoptosis in human neutrophils during severe sepsis and septic shock
We evaluated neutrophil activation by measuring its phagocytic ability and oxidative burst
activity in 16 patients with sepsis and 16 healthy volunteers. We also focused on neutrophil …
