Obesity is thought to be a main risk factor of insulin resistance and diabetes mellitus. Study on concentrations of lipids in the tissues of animals with experimental model of obesity resulting in insulin resistance remains currently central. The work was initiated to study the spectrum of lipids and their concentrations in the tissues of experimental animals with the induced alimentary obesity.Alimentary obesity with concurrent insulin resistance was in...

Causing production of free radicals and reduction of antioxidant system activity, in the pancreatic β-cells, in particular, resulting in reduction in insulin production and consequently to hyperglycemia, oxidative stress could be a pathogenetic mechanism of morbidity in diabetes mellitus. Search for and development of medicines with antioxidant and hypoglycemic activity remains urgent.Aim: The work was initiated to study antioxidant and hypoglycemic...

Obesity is considered as a major factor of insulin resistance and diabetes mellitus risk. Study on lipid composition of tissues in obesity is relevant in understanding of mechanisms underlying insulin resistance.Aim: The work was initiated to study lipid composition of liver and skeletal muscles tissues in rats with alimentary obesity.Materials and methods: Obesity was induced in rats leading an inactive lifestyle with prolonged hi...

There are three main types of diabetes mellitus: type 1 diabetes mellitus (T1DM), type 2 diabetes mellitus (T2DM) and gestational diabetes, with the first two types making about 99% of cases.According to its nature, type 1 diabetes mellitus (T1DM) is considered as a typical autoimmune disorder characterized with specific autoantibodies. Immunological markers of the diabetes mellitus onset can be found not only in T1DM with its specific clinical picture, ...

The fat tissue inflammation and insulin resistance formation are common in obesity and type 2 diabetes mellitus. The tumor necrosis factor–α (TNF-α), a pro-inflammatory cytokine, was found to be a key one in onset and progression of insulin resistance, blocking the insulin signaling pathway and hampering the gene expression of GLUT4, the intracellular insulin-regulated glucose transporter in body tissues. Rise in the TNF-α concentration in blood serum is b...

Associated with the increased generation of free radicals and reduced activity of antioxidant system, oxidative stress is a pathogenetic mechanism underlying the onset of diabetic complications. Antioxidants are known to facilitate normalization of lipid peroxidation, composition, structures and functions of biological membranes. Antioxidants are universal membrane-trophic agents protecting against damaging factors. Plant antioxidants play a significant role in treatment of di...

Obesity of varying severities can be seen in the vast majority of patients with type 2 diabetes mellitus (DM2). Oxidative stress is considered as a key pathogenetic link in the formation of metabolic disorders in obesity. The work was initiated to assess intensity of oxidative stress in obese patients with DM2.Materials and methodsThe patients were divided into 3 groups. Patients with DM2 and BMI > 30 kg/m2 were incl...
