Figure 4.

Effect of curcumin on retinal nitrotyrosine levels in diabetes. Nitrotyrosine-EIA kit was used to quantify nitrotyrosine in the retina. Each sample was measured in duplicate. The figure represents mean ± SD of 6 rats each in normal and diabetes + curcumin groups and 7 rats in diabetes group. *P < 0.05 compared to normal, ^#P < compared to diabetes + curcumin.
