Effect of EAFA on NO production (a) and cell viability (b) in LPS/IFNγ-stimulated and unstimulated RAW264.7 cells. RAW264.7 cells were treated with EAFA (50–200 μg/mL) for 24 h with or without LPS/IFNγ stimulation. Nitrite concentrations in the culture medium were determined by the Griess reaction. Changes in survival are represented as percentages of the control group. Bars represent the mean ± SEM. Three independent experiments were performed. ^## P < 0.01; ^# P < 0.05 versus control group; **P < 0.01; *P < 0.05 versus model group.
