[Table/Fig-5]:

Disease duration-related increased of protein oxidation in patients with Diabetes Mellitus (DM) and Diabetes Mellitus Neuropathy (DMN). Levels of protein carbonyl contents in the serum samples of patients with DM group 1 (DMG1; disease duration≥15 years), DM group 2 (DMG2; disease duration<15 years), DMN group 1 (DMNG1; disease duration≥15 years), DMN group 2 (DMNG2; disease duration<15 years) and normal humans (NH). #p<0.01 versus NH; #p<0.05 versus *; ##p<0.05 versus **; ##p<0.001versus NH. Comparison analysis was performed using one-way ANOVA followed by Tukey’s post-hoc test.
