[Suppression of neutrophil immune function in rabbit models of hemorrhagic shock complicated by intra-abdominal hypertension].

Objective: To investigate the effects of hemorrhagic shock and intra-abdominal hypertension (IAH) on inflammatory responses of peripheral circulating neutrophils such as intracellular cytokine production, phagocytic capacity and expression of nuclear factor (NF)- kappaB.

Methods: Twenty-four rabbits were divided equally into 4 groups including a hemorrhagic shock (HS) group complicated by abdominal compartment syndrome (ACS) (Group A), a HS group (Group B), a ACS group (Group C) and a normal control group (Group D). Intracellular interleukin (IL)-8 production in the peripheral neutrophils were measured in the rabbits by flow cytometry, phagocytic function of the neutrophils evaluated by a chemiluminescence method and the NF-kappaB expression detected by immunocytochemistry before, immediately and 4 h after the traumatization.
