The cytotoxicity and effect on intracellular oxidative stress in Hs68 of TCE. a Cell viability (%) of human fibroblasts (Hs68), human keratinocytes, and mouse melanoma cells treated with TCE; b Cell viability of Hs68 after treatment with TCE with or without 150 μM hydrogen peroxide (H2O2) exposure. c Repressive effect of TCE on H2O2-induced intracellular oxidative stress in Hs68. Significant difference versus control: *p < 0.05; **p < 0.01; ***p < 0.001. Significant inhibition versus H2O2-exposed group: #p < 0.05; ##p < 0.01
