Effect of APH on nitrosative stress on macrophages RAW 264.7. The pre-treatment with APH at 0.05 and 0.1 mg/mL considerably reduced total NO levels after stimulation with H₂O₂ for 10 min (a). MDA levels were significantly increased in the cell lysates following H₂O₂ stimulation. Lipid peroxidation was significantly attenuated by the pre-treatment with APH at 0.05 and 0.1 mg/mL (b). Data are representative of at least three independent experiments. ## p < 0.01 vs. H₂O₂; *** p < 0.001 vs. Ctr.
