[Retracted] The Healing of Oxidative Injuries with Trehalose in UVB-Irradiated Rabbit Corneas

Figure 2

Production of reactive oxygen species (ROS) in the UVB-irradiated corneas (once daily for 4 days) treated with buffer or 3% or 6% trehalose eye drops examined by the dihydroethidium (DHE) assay. The intensity of fluorescence was scaled by integral optical density. (a) Compared to buffer-treated corneas, the oxidative stress in the corneal epithelium was reduced by 3% trehalose and strongly suppressed by 6% trehalose. (b) In the corneal epithelium treated with buffer alone, the intensity of fluorescence was significantly higher compared to that of fluorescence of the control epithelium or corneal epithelium treated with trehalose eye drops. The values with asterisks are significantly different (, ) from those of buffer-treated corneas. Buffer: ; 3% trehalose: ; 6% trehalose: ; control ; /group. Scale bars: 50 μm.
