The effect of the combination of fucose-mannose ligand (FML) with glycyrrhizin (GL) on the production of nitric oxide (NO) by activated macrophages. Co-treatment with FML and GL significantly increased NO production in activated macrophages in comparison with activated macrophages treated with PBS, FML or GL alone. Results represent the mean (mean ± SD) of three independent experiments with macrophages from seven mice per experiment (*P < 0.05, **P < 0.01). Abbreviations: PBS, phosphate-buffered saline; ns, not significant
