| Abstract: | The effect of acute streptozotocin-induced diabetes mellitus on the systemic hemodynamic parameters was studied in conscious rats by thermodilution technique. Male Wistar rats were made diabetic with a single intravenous injection of streptozotocin (STZ, 50 mg/kg). The most important finding of this work was the elucidation of the systemic vasodilation and increased cardiac index one day after STZ injection. Such alteration in hemodynamic parameters could result in the increased blood flow and capillary hypertension in some vascular beds and, therefore, be considered as a pathogenic factor in the development of diabetic microangiopathy. |
