Figure 4. Effects of oral administration of crocetin on the expression of occludin in the murine RVO model. A: Representative images of western blotting showing the expression level of occludin 24 h after the administration of crocetin. B: The expression level of occludin was decreased in the vehicle-treated group. Oral administration of crocetin inhibited the reduction of expression of occludin. Data are shown as mean ± standard error of the mean (SEM; n=6 or 7). ^#p<0.05, ^##p<0.01 (versus control group; Student t test). *p<0.05, **p<0.01 (versus vehicle group; Student t test).
