Figure 3: Neuroprotective effect of JDS and its herbal components in H2O2-treated HT22 cells. Cells were seeded on 96-well plates and cotreated with various concentrations of JDS and its seven components, and H2O2 (250 μM) for 6 h. Cell viability was assessed using the CCK-8 assay. Results are shown for JDS (a), US (b), CM (c), ZO (d), PG (e), PT (f), CU (g), and PC (h). The results are expressed as the mean ± SEM of three independent experiments. versus vehicle control cells, , , and versus H2O2-treated cells.
