aInflammatory mediators production (absolute values in pg/mL). Differences in the release of TNF-α and CCL-2 elicited by the extracts were analyzed by one-way ANOVA followed by multiple comparisons of Newman-Keuls. In each extract, indicates significant inhibition of TNF-α or CCL-2 release in comparison to LPS-stimulated cells (). Dexamethasone (0.1 μM) was employed as positive control.
