[Retracted] Molecular Hydrogen Effectively Heals Alkali-Injured Cornea via Suppression of Oxidative Stress

Figure 4

The immunohistochemical detection of α-SMA in injured corneas treated with H2 dissolved in PBS (H2) or with PBS free of H2 (buffer) examined on day 20 after the injury. The expression of α-SMA was high in the corneal stroma of injured corneas treated with buffer (a) (arrow) and in retrocorneal membrane (arrow) (b), whereas in injured corneas treated with H2 the expression of α-SMA was low in the corneal stroma (c) and the retrocorneal membrane was not developed (d) compared to control cornea (e, f). Scale bars: 50 μm.
