| Outcome Measures: |
Primary: The evaluation of the changes in Flow-Mediated Dilatation (FMD) at 12th and 24th weeks compared to the baseline level, as a Measure of Endothelial Function, As soon as type 2 DM patients which were randomly recruited either to the Gliclazide MR arm or the Insulin Detemir arm reach to target glycemic levels (0. week), flow-mediated dilatation test, which is a basal tests showing endothelial function will be performed. This basal test will be reapeated in each study subject, 12 weeks and 24 weeks after reaching the target glycemic levels., The basal, 12th and 24th week after reaching the target glycemic levels|The Changes in the Peripheral Blood Levels of TNF-α, IL-6, MCP-1, sICAM-1, sVCAM-1, vWF, E-selectin, P-selectin, Endothelin-1, PAI-1, tPA and HMW Adiponectin at 12th and 24th weeks compared to the baseline level, as Measures of Inflam. and Coagulation, As soon as type 2 DM patients which were randomly recruited either to the Gliclazide MR arm or the Insulin Detemir arm reach to target glycemic levels (0. week), basal tests showing endothelial function as well as inflammatory and coagulation status such as flow-mediated dilatation and peripheral blood TNF-α, IL-6, MCP-1, sICAM-1, sVCAM-1, vWF, E-selectin, P-selectin, endothelin-1, PAI-1, tPA and HMW adiponectin levels will be performed. These basal tests will be reapeated in each study subject, 12 weeks and 24 weeks after reaching the target glycemic levels., The basal, 12th and 24th week after reaching the target glycemic levels | Secondary: Calculation of Body-mass Index, Body Fat Mass, Level of Insulin Resistance and the Insulin Secretion Capacity of Pancreatic Beta Islet Cells as Measures to Identify the Effects of Gliclazide and Insulin Detemir Treatments on Diabetes Progression, As soon as type 2 DM patients which were randomly recruited either to the Gliclazide MR arm or the Insulin Detemir arm reach to target glycemic levels (0. week), mixed-meal test and body-fat mass determination using bioimpedence analysis will be performed. These tests will be reapeated in each study subject, 12 weeks and 24 weeks after reaching the target glycemic levels., The basal, 12th and 24th week after reaching the target glycemic levels
