Figure 2

Cell protective effects of RL on PM10-treated A549 cells. (a) Cell viability of A549 cells treated with RL (15.625–500 μg/mL) for 25 h. (b) RL (15.625–250 μg/mL) was pretreated 1 h prior to PM10-induced cell damage in A549 cells and incubated for 24 h with PM10 (100 μg/mL). Cell viability of A549 cells was confirmed by MTT assay. Statistical significance was analyzed by unpaired t-test (one-tailed). Values are means ± SEM. compared to the control group. ; compared to only PM10-treated group.
