Outcomes and Timepoint

Section to complete information about primary and secondary outcomes including. It includes the metric or method of measurement used and, the time point for every outcome.

Primary outcome(s):

Global indicator: Perioxidation Potential (PP): Value of reference: 7,32 + - 0,56 uM,it will consider positive answer when the final value of PP diminishes in at least an unit (final value - initial value). This result will be in correspondence with the mean of the peroxidation potential (PP) and its decrease in 1.5 times of the group of diabetic treated with extract of the bark of Mangifera L. indicates (Vimang®) with regard to the group that is administered placebo, in the one that the variation in an unit corresponds it previously described, according to the used statistical program. This variable will be measured to the beginning, to the 3 months of initiate the treatment and to the 6 months.

Key secondary outcomes:

Improvement of anyone of the following variables: that is to say that the values are included in the non diabetics' reference interval or diabetics with good glucemic control Enzymes: Superoxide dismutasa (SOD): Value of reference: 1,45 + - 0,15 /mL/min Catalase (CAT):value of reference: 161,5 + - 12,5 or / L/min CAT/SOD: value of reference: 0,11 + - 0,02 Biomolecular damage: MDA: Value of reference: 1,74 + - 0,27u Hydroperoxides (ROOH): Value of reference: 103 + - 17uM Advanced products of the oxidation of proteins (APOP): Value of reference: 12,13 + - 0,93uM In leukocytes: Fragmentation of the DNA Low molecular weight antioxidant. Glutation reduced (GSH): Value of reference: 786-1156 mg/L These variables will be measured to the beginning, to the 3 months of initiate treatment and the 6 months.
