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

Figure 5

The immunohistochemical expressions of iNOS and IL-1β in UVB-irradiated corneas of rabbits treated with trehalose (3% or 6% concentration) drops or buffer drops for fourteen days after the end of repeated irradiation. The expressions of iNOS and IL-1β are nearly absent in control corneas (a, b) and in the irradiated corneas treated with 6% trehalose (e, f). In corneas treated with 3% trehalose (c, d), slight expressions of iNOS and IL-1β are present. In contrast, after the treatment of corneas with buffer drops, iNOS and IL-1β are highly expressed in corneas (g, h). Scale bars: 50 μm. The expression of genes for iNOS and IL-1β summarized are shown (i, j). The values with asterisks are significantly different (, ) from those of buffer-treated corneas.
