Fig 2: Effect of resveratrol on relative cerebral COX-2 gene expression (COX-2/β-actin) in studied groups. An agarose gel electrophoresis showed PCR products of mRNA gene expression level of COX-2 gene and normal control gene (β-actin). Lane DNA ladder: 100pb DNA marker, lanes N, D, D + Res, DIR, DIR + Res represent control, diabetic, diabetic treated with resveratrol, diabetic with cerebral ischemic-reperfusion, diabetic with cerebral ischemic-reperfusion treated with resveratrol groups. (*) Significantly different from N at P < 0.01. (#) Significantly different from D at P < 0.01. (a) Significantly different from D at P < 0.05. (b) Significantly different from DIR at P < 0.05.
