| Popis: | Background. Diabetes mellitus is accompanied by oxidative-nitrative stress, which is caused both by an increased generation of the Reactive Oxygen Species and the Reactive Nitrogen Species under the conditions of this pathology and by the disorders of the antioxidant defense system, especially its enzymatic part. This leads alterations in the morpho-functional state of cells, organs, and the whole organism. Free radicals are involved in the destruction of pancreatic cells in type 1 diabetes mellitus, which leads to even greater inhibition of insulin secretion, worsening of the course of the disease and occurrence of diabetic complications. The complications of diabetes mellitus include often diagnosed cardiovascular diseases. Therefore, the use of treatments characterized not only by hypoglycemic properties for normalization of blood sugar level in diabetes mellitus, but also by antioxidant properties for normalization of oxidative/antioxidant balance of the organism in the studied pathology can be promising. Scientists pay a great attention to the study of substances with such properties, especially natural phenolic compounds of grape, which are also characterized by immunomodulatory properties. Materials and Methods. The study was performed on cardiac tissues of control rats, control animals treated with wine polyphenolic complex concentrate, animals with streptozotocin-induced diabetes mellitus and animals with experimental diabetes mellitus treated with a concentrate of wine polyphenolic complex. The activity of catalase, superoxide dismutase, glutathione peroxidase and glutathione reductase were detected to examine the corrective effect of the concentrate of red wine natural polyphenolic complex on the state of the enzymatic part of the antioxidant defense system. Results. The results have shown the normalization of activity of catalase, superoxide dismutase, and changes in the activity of enzymes of glutathione cycle after oral administration of polyphenolic complex concentrate for 14 days to rats with streptozotocin-induced diabetes mellitus. Conclusions. The results confirm a hypothesis about the antioxidant effect of the studied concentrate and the ability of natural polyphenolic complexes to serve as the basis for new drugs for treatment of diabetes-induced disorders. |
