Effects of VYE on mRNA expression of (a) iNOS, (b) COX-2, and (c) HO-1 in macrophages. Cells were treated with (a, b) LPS alone or with LPS and VYE for 24 h and (c) VYE alone for 3 h. Data represent the means ± SE of determinations from three independent experiments. ** p < 0.001 compared to the LPS-stimulated value
