Figure 6. Effect of standardized extract of Zingiber officinale on retinal NF-kB p65 expression after 24 weeks of treatment as shown with western blot. A: Intense bands were seen on western blot in DC groups but not in 6-G treated group (n=4 for all groups). B: Quantification of P-NF-kB p65 in the retinas of three groups of animals using enzyme-linked immunosorbent assay (ELISA;
n=4 for all groups). Each value represents mean ± standard deviation (SD). NC = normal control; DC = diabetic control; 6-G
= Zingiber officinale–treated diabetic group. *p<0.0001 versus the NC group; #p<0.001 versus the DC group.
