Effect of PDN-SCFE on RAW 264.7 murine macrophage cell viability. Cells were treated with indicated concentrations of PDN-SCFE for 24 h. Then, cell viability was determined by MTT assay as described in methods. The viability of cells in the absence of extract was taken as 100% (Control). The results are expressed by percentage of surviving cells over control group. Data represent mean ± SD of three separate experiments
