Fig. 3. Effects of hypoxia-normoxia and hypoxia-hyperoxia conditions on inflammatory response of neutrophils. Each value has been calculated as ratio (%) relative to control group. In hypoxia-normoxia group, hydrogen peroxide (H2O2) and Toll-like receptor 4 (TLR4) production were higher and apoptosis was delayed compared to control group. In hypoxia-hyperoxia group, production of H2O2 was increased and apoptosis was delayed compared to control group; however, TLR4 receptor production was restored to control group. Mean ± standard deviation (n = 18). *P < 0.05, paired t-test.
