Cell viability of NHOKs after they had been exposed to different doses of H2O2 for different durations. (a) NHOKs were seeded in medium containing H2O2 (range: 0.01–100 mM). The cells were incubated for 15 min, 30 min, 1 h, 2 h, 4 h, and 8 h. Cell viability in culture medium alone was the negative control. The experiment was repeated 5 times. (b) Cell viability of NHOKs cultured in medium containing 10 different doses of H2O2 (range: 1–10 mM). The experiment was repeated 5 times
