Recent studies also show that human obesity is associated with vascular structural and functional modifications, specially at large and medium-sized arteries. Epidemiological studies have confirmed that obesity is a significant risk factor for the development of proteinuria and end-stage renal disease in a normal population. With the objective to determinate morphological changes related to cardiac, vascular and renal remodeling in an experimental model of monosodium glutamate (MSG)-induced obesity and the effect of metformin at this finding. Twenty five rats were studied and divided into five groups: control with 16 e 22 weeks (CON-16 and CON-22); obese with 16 and 22 weeks (MSG-16 e MSG-22), and obese + metformin (MET-22) 300mg/Kg/day per oral. The characterization of insulin resistance was done through measurement of plasma insulin and calculation of HOMA-IR index. The morphological analysis and the quantification of myocardial collagen were carried out by Image Pro Plus analysis system. The systolic blood pressure was slightly higher in MSG-22 group, reaching statistical significance when compared to MSG-16 group (122±2 vs 108±2 mmHg, p
