H 2 O 2 -mediated loss of HDPPC viability was rescued by arctiin treatment. (A) WST-1 cytotoxicity assays of HHDPCs treated with various doses of arctiin. Each bar represents the mean ± SD from three independent experiments. (B) Arctiin dose-dependently inhibited H2O2-induced cytotoxicity as measured with WST-1 assays. The graph represents the mean ± S.D. of relative cell viability from triplicate experiments. *p < 0.05 compared with H2O2-treated HHDPCs.
