Figure 6. Effect of fasudil on the production of heme oxygenase-1 (HO-1) protein in the mice corneas after alkali burns. A: Representative image of western blotting bands for HO-1 protein in the murine corneas on day 4 after alkali burns. The intensity of fluorescence was scaled by integrated density. B: The protein expression of HO-1 after treatment with 100 μM fasudil eye drops was significantly enhanced compared to after phosphate-buffered saline (PBS) treatment (n=5 per group, * indicates p<0.05).
