Abstract:

The progression of diabetes mellitus leads in time to the development of serious cardiovascular complications. Pycnogenol® (PYC) belongs to strong antioxidants that may interfere with different pathways playing an important role in diseases associated with oxidative stress. Metformin (MET), commonly used antidiabetic drug, has cardio-protective effects via activation of AMP kinase (AMPK). In our study, we examined the effects of PYC as add-on drug to metformin therapy in streptozotocin (STZ)-induced diabetic rats. Our results revealed that both used agents, PYC and MET, showed improvement of blood glucose levels, vascular reactivity, left ventricular hypertrophy, expression of AMPK, glucose transporter 4 (GLUT4) and calcium/calmodulin-dependent protein kinase II (CaMKII) in left ventricle of the hearts. However, the combination of these interventions has failed to possess higher efficacy. Copyright © 2016 John Wiley&Sons, Ltd.
