FEATURES OF THE SYSTEM OF ANTIOXIDANT PROTECTION AND LIPID PEROXIDATION IN MICROANGIOPATHIES AGAINST A BACKGROUND OF TYPE 2 DIABETES MELLITUS

The article presents the results of an experimental study of the AOР and LPО system in animals with simulated complications of the microcirculatory tract (diabetic retinopathy, diabetic nephropathy) on the background of type 2 diabetes. It was found that the group of animals with type 2 diabetes has increased the level of DC, TBC-products and MDA; catalase and RG levels decreased. In animals with simulated DN, AOP disorders were more pronounced compared to animals with DR. This trend can be explained by the fact that in addition to hyperglycemia in these animals, the excessive formation of free radicals contributes to metabolic shifts in ischemic areas of tissues and organs. Disturbance of balance in AOP and LPO in type 2 diabetes triggers a pathogenetic cascade of development of complications of the microcirculatory tract and is accompanied by a tendency to further increase the generation of reactive oxygen species and activation of POL in microangiopathies.
