Disfunction membrane-receptor system blood cells in childrensuffering from diabetes type i and ii

Abstract

When metabolic failure in children and adolescents with diabetes, are violations of the structural and functional properties of membrane - the receptor apparatus of cells, accompanied by a decrease in ATP levels, inhibition of activity of membrane-bound enzyme Na+,K+-ATPase, a sharp decrease in insulin binding receptor activity and decrease glucose uptake by cells that indicates a decline in cell sensitivity to insulin.Diabetes in children and adolescents occurs with lipid disorders, activation of the processes of lipid peroxidation, manifested increasing concentrations of both primary and secondary products of lipid peroxidation, changes in structural and functional properties of erythrocyte membranes, as well as disturbances in the antioxidant defense system. Changes in the studied indexes depend on the type of diabetes and duration of the disease.Imbalance in the system LPO-AOD in the background shows the development of dyslipidemia, oxidative stress, particularly pronounced in type 2 diabetes.
