Figure 3: Cytoprotective effects of aqueous extract of Cordyceps sinensis in A549 cells exposed to different oxygen percentages (0.1, 0.5%, 1%, or 5% O2; (a)–(d) for 48 h. Cells exposed to hypoxia showed cell death (dark gray bar) in comparison to unexposed cells (black bar) which was dependent on oxygen percentage. Treatment of cells with aqueous extract of Cordyceps sinensis increased cell survival following hypoxia exposure and the efficacy of extract was dose dependent (light gray bars). * .
