Figures & data

FIG. 1 IL-1α release from cultured macrophages after treatments of JP-8, substance P, [Sar9 Met (O2)11] substance P, and their combinations. Cells were cultured for 24 hr and the IL-1α levels in culture supernatant were measured by ELISA kits. Data were presented as mean values ± SEM. * p < 0.05 when compared to the control value. #p < 0.05 when compared to 0.2 μ g/ml JP-8 exposure group. %p < 0.05 when compared to 1.6 μ g/ml JP-8 exposure group. Results are the average of three independent experiments.
