Suppression of Inflammatory Mediators by Cruciferous Vegetable-Derived Indole-3-Carbinol and Phenylethyl Isothiocyanate in Lipopolysaccharide-Activated Macrophages

Figure 1

Effects of I3C (a) and PEITC (b) on lipopolysaccharide- (LPS-) induced NO released into the medium by RAW 264.7 cells. Cells were treated with LPS (330 ng/mL) and various concentrations of I3C and PEITC for 24 hours. The nitrite contents in the medium were then determined using the Griess reagent. Values represent the mean $\pm$ SD from three measurements, and LPS group is regarded as 100%. Data for the same parameter with different letters (a–f) significantly differ (P $<\hspace{0.17em}\hspace{0.17em}$.05).
