VEGF levels in curcumin-treated rats. VEGF concentrations were measured in the retina of rats in normal, diabetes and diabetes + curcumin groups using an ELISA kit from R&D Systems. Results are presented as mean ± SD of 6 rats in diabetes and 7 rats each in normal and diabetes + curcumin groups. *P < 0.05 compared to normal, and #P < 0.05 compared to diabetes + curcumin.
