Figure 2: Oxidative markers in the serum and aorta homogenates. Total GSH levels (a), SOD levels (b), and MDA levels (c) in serum samples from different groups were measured after 12 weeks of treatment (). Total GSH levels (d), SOD levels (e), and MDA levels (f) in aorta homogenates from different groups were measured after 12 weeks of treatment (). (g) and (h) show the immunohistological analysis of 3-nitrotyrosine in the aorta, magnification 200x. The scale bar indicates 40 μm. IOD: integrated optical density. . , , compared with the control group. , compared with the DM group.
