Characterization of Blood Oxidative Stress in Type 2 Diabetes Mellitus Patients: Increase in Lipid Peroxidation and SOD Activity

Figure 3

SOD, CAT, and GPX activities. (a) Total erythrocyte SOD in diabetic patients, pre-DM and controls; *DM2 versus pre-DM, and C; (b) total erythrocyte SOD activity, *DM2(+)SAH versus pre-DM and C(+)SAH; (c) total erythrocyte SOD activity, *DM2(−)LPO versus C(+)SAH; **DM2LPO versus pre-DM, C(+)SAH and C(−)SAH; (d), (e), and (f) erythrocyte CAT activity; (g), (h), and (i) extracellular GPx activity in plasma. (j) SOD/CAT ratio, *DM2 versus C, (k) SOD/CAT ratio, *DM2(−)SAH versus C(+)SAH, and (l) SOD/CAT ratio, *DM2LPO versus C(+)SAH. Values are presented as mean ± SEM. ANOVA, followed by Tukey’s multiple comparison test. * ; ** .
