Abstract

Metabolic syndrome (MS) is one of the most important challenges in public health and biomedical research. To control this disease, research in rodent models that closely mimic the MS in humans is essential. In this study, a rat model of MS was developed in male Sprague-Dawley rats by feeding them a high-carbohydrate, high-fat (HCHF) diet with a 15% fructose solution added to their drinking water.  Rats in the control group were fed a standard chow diet. During the 10 weeks on a HCHF diet, rats had developed signs of MS, including hypertension, dyslipidemia, hyperglycemia and impaired glucose tolerance. These changes progressively increased throughout 16 weeks of the feeding period. Their abdominal fat pads and organ wet weights (heart, liver and kidneys) significantly increased (P<0.05).  Moreover, a significant decrease in hepatic and renal functions was also observed in HCHF diet-fed rats (P<0.05). Overall results suggest that chronic consumption of a HCHF diet by normal rodents provides an adequate rodent model to mimic human metabolic syndrome. This rat model of MS may be useful for studying the pathophysiological basis of MS in humans and for testing potential therapeutic interventions.
