Correction of morphofunctional disorders with grapes polyphenols in rats with experimental metabolic syndrome
Abstract
The aim of this work was to study the effect of grape polyphenols on target organs in rats with experimental metabolic syndrome. Methods. Grape polyphenols were used in Wistar rats for 12 weeks. All rats received a standard diet. The animals were divided into 6 groups: group 1, control, received drinking water; group 2, the second control, and four experimental groups received a 2.5% fructose solution for drinking. The first experimental group additionally received a drug, Fenocor, containing polyphenols at 181.53 g/dm3; the second experimental group — wine material containing polyphenols at 1.73 g/dm3; the third experimental group — wine material containing polyphenols at 4.33 g/dm3; and the fourth experimental group — wine material containing polyphenols at 8.58 g/dm3. At the end of experiment, morphological studies of visceral adipose tissue, myocardial tissue, and hepatic tissue were performed. Results. The treatment of rats with experimental metabolic syndrome with grape polyphenolic products at a concentration of 181.53 g/dm3 minimized morphological and functional disorders in
visceral adipose tissue (intensity of lymphoplasmocytic infiltration was decreased), myocardium (muscle fibers had normal structure with only occasional adipocytes between them), and liver (only slight focal degenerative changes were observed in hepatocytes). Conclusion. The study indicated a possibility of using wine materials with the highest concentration of polyphenols and the drug Fenocor for correction and prevention of damages in metabolic syndrome.
