Outcomes of CCK-8 assays of HEI-OC1 cells. Cell viability was analyzed using CCK-8 assays. HEI-OC1 cells were treated with H₂O₂ and different concentrations of SL. Viability differences between the control and H₂O₂ groups under varying concentrations of SL were compared. The difference in cell viability between the control and H₂O₂ groups was larger at low concentrations of SL. However, as the concentration increased, viability decreased. There were significant differences between the control and H₂O₂ groups at three lower concentrations of SL (0, 10, and 25 µL). Meanwhile, there were no significant differences at the three higher concentrations (50, 100, and 250 µL). *p < 0.05, **p < 0.01, and ***p < 0.001. NT: no treatment.
