Characteristics of active oxygen forms and antioxidants at experimental metabolic syndrome and its remodeling by grape polyphenols

Adipose tissue in obesity produces more active oxygen forms and inflammatory cytokines, which results in the development of a systemic inflammatory response syndrome (SIRS) and a metabolic syndrome (MS). Recently, there has been a growing interest in natural products for oxidative stress remodeling. Therefore, it is relevant to study grape polyphenols (GPs) to develop certain techniques for oxidative stress prevention and treatment. The goal of the paper is to examine antioxidant profiles in MS, and the efficacy of its pathogenetic correction with GPs. Materials and Methods. The authors estimated the ratio of peroxidase (PA) activity and thiobarbituric acid active products (TBA-APs), and the ratio of ceruloplasmin (C) and PA. Results. The authors observed stereotypical changes in the systems of antioxidant and antiproteolytic protection in MS. Thus, with MS, there was recorded a decrease in PA/TBA-AP ratio (2.3 compared with 16.6 in norm) and an increase in C/PA ratio (3...
