详细技术说明

Oxidative stress represents an imbalance between the production and manifestation of reactive oxygen species (ROS) and a biological system's ability to readily detoxify the reactive intermediates or to repair the resulting damage. In humans, oxidative stress is involved in many diseases. Increasing evidence in studies suggests that oxidative stress plays a major role in the pathogenesis of both types of diabetes. Free radicals are formed disproportionately in diabetes by glucose oxidation, nonenzymatic glycation of proteins, and the subsequent oxidative degradation of glycated proteins. Abnormally high levels of free radicals and the simultaneous decline of antioxidant defense mechanisms can lead to damage of cellular organelles and enzymes, increased lipid peroxidation, and development of insulin resistance. It is also known that the amount of glycosylation on the surface of an erythrocyte changes by exposure to oxidative stress and the electric charge of an erythrocyte depends on the amount of glycosylation on the surface of the erythrocyte. Researchers have invented a device to evaluate oxidative stress by measuring the amount of glycosylated erythrocytes using an electrochemical measuring method. This device can be used to measure the level of oxidative stress in diabetes patients and is useful to predict the risk of diseases induced by oxidative stress.

*Abstract
