Nitric oxide (NO) release following 24 h stimulation of RAW264.7 murine macrophage cells with lipopolysaccharide (LPS) in the absence or presence of extracts of O. subscorpioidea (B), U. chamae (C), and of Prednisolone (D) and Diclofenac (E). A describes the standard nitrite curve obtained. Each bar represents Mean ± SEM (n = 3); ^*p < 0.05, **p < 0.01, ***p < 0.001 versus vehicle-treated control (C); ^ap < 0.05, ^αp < 0.01, ^βp < 0.001 versus LPS-treated cultures using one-way ANOVA followed by Dunnett’s post hoc multiple-comparisons test
