Hypericum triquetrifolium—Derived Factors Downregulate the Production Levels of LPS-Induced Nitric Oxide and Tumor Necrosis Factor-α in THP-1 Cells
Figure 3
Dose-dependent inhibition of LPS-mediated production of NO by H. triquetrifolium extracts. For each concentration treatment, the level of NO release is represented as a percentage of the control set at 100%. Values represent mean ± SD (*P < .05 significant as compared with LPS alone) of three independent experiments carried out in triplicate.
