Effects of three Glycine species, genistein, and daidzein on lipopolysaccharide (LPS)-induced cell viability (a) and NO production (b) of RAW 264.7 macrophages. Cells were incubated for 24 h with 100 ng/mL of LPS in the absence or presence of three Glycine species (0, 62.5, 125, 250, 500 and 1000 μg/mL), genistein, or daidzein (5 and 10 μg/mL). Samples were added 1 h before incubation with LPS. Cell viability assay was performed using MTT assay. Nitrite concentration in the medium was determined using Griess reagent. The data were presented as mean ± SD for three different experiments performed in triplicate. ^###Compared with sample of control group. *p < 0.05 and **p < 0.01 were compared with LPS-alone group
