Concentration of IL-1β (A) and IL-1Ra (B) detected using ELISA in a total of 15 patients. Note that due to low signal intensity in the case of “Baseline” IL-1β, the concentration was set to 0.5 pg/ml. Shown is the mean ± SE. Statistical analyses were carried out as described in the method section. IOI = intravenous oxygen insufflation; ACS = autologous conditioned serum
