| Abstract | Cardiovascular disease is one of serious complications of chronic diabetes. The objective of this study was to investigate the effects of HS-WE and gallic acid on ventricular function in high fat diet-streptozotocin (HFD-STZ)-induced Type 2 diabetic rats. Male Sprague-Dawley rats were used. The normal control group was fed normal rat chow. Diabetic groups were fed HFD for 4 weeks and followed by intraperitoneal injection of STZ 30 mg/kg. The diabetic rats were divided into 5 groups which were orally administered daily with distilled water, 50% propylene glycol, HS-WE (500 mg/kg), gallic acid (50 mg/kg), and metformin (200 mg/kg) for further 8 weeks. At the end of all treatments, the levels of fasting blood glucose (FBG), serum insulin, Homeostatic Model Assessment-Insulin Resistance (HOMA-IR), plasma and heart malondialdehyde (MDA), heart superoxide production and left ventricular function were determined. Diabetic control rats showed significant increases in levels of FBG, HOMA-IR, MDA and superoxide production. In left ventricular function examination, an increase in diastolic ventricular pressure (DVP) and a decrease in (-)dP/dt were observed. HS-WE and gallic acid treated groups had significant decreases in FBG, HOMA-IR, plasma MDA, heart MDA and heart superoxide production as well as a decrease in DVP and an increase in (-)dP/dt when compared to diabetic control group. These results indicated that HS-WE and gallic acid improve diabetic induced diastolic dysfunction and this effect may be mediated via their antioxidant activities. |
