Factors evaluation of oxidant–antioxidant malondialdehyde, plasma total antioxidant and vitamin C in type 1 diabetes patients compared with healthy people

One of the most important prevalent and chronic diseases is diabetes. The conditions of oxidative stress and missing equilibrium of antioxidants have an important and main role in emerging and development of this disease. Evaluating the factors of oxidant – antioxidant Malondialdehyde, plasma total antioxidant and Vitamin C in type 1 diabetes patients is the main purpose of the present study.
In the present case – control study, 30 patients suffering from type 1 diabetes were compared with 30 healthy persons. The capacity of plasma total antioxidant was measured with FRAP method. Malondialdehyde was measured as final production of lipids peroxidation based on Hadley and Draper method and evaluation of vitamin C level using Roe and Queter method. Statistical analysis was done using T statistical test and SPSS soft ware. P <0.05 was considered as significant level.
The mean and standard deviation of plasma total antioxidant in persons with case 35.11±8.04 and in persons with control 36.19±2.3 µmol/L that statistically was significant (p= 0.000). The amount of MAD as a factor lipids peroxidation in persons with case 16.52±1.14 and in persons with control 15.42±2.34 µmol/L (p= 0.056). Vitamin C level in persons with case and control 7.43±0.67 and 8.76±2.86 mg/dl (p= 0.000).
In the present research, the level of plasma total antioxidant and vitamin C in patients suffering diabetes has been significantly less than control group. Malondialdehyde level showed a significant increase in the case group. Therefore, it is recommended to consume and use natural antioxidants much more in order to reduce damages originate from free radicals.
