Oxidative stress is known to be related to various diseases such as inflammation, carcinogenesis, arteriosclerosis and ischemia-reperfusion injury, and is also a major cause of aging. For the prevention of diseases and control of aging, evaluation and control of oxidative stress in vivo may become essential. We have developed the new Oxidative Stress Profile(OSP), a total diagnostic system which provides information about oxidative stress inside human body. The OSP system consists of a number of biomakers including oxidative damage markers, prooxidant factors, antioxidants and life style-related markers. The result is shown in a two dimensional plot form. We measured a combination of biomarkers for oxidative damage of biological components, serum antioxidants and analyzed oxidative stress. The result show that oxidative stress was elevated in diabetic patients in comparison with normal controls. Oxidative stress is also elevated in smokers in comparison with non-smokers. It is also interesting to find that oxidative stress can be greatly reduced by the improvement of life style such as diet. Oxidative Stress Profile system may become a powerful tool for the evaluation of oxidative stress in vivo, and may be useful in prevention of diseases, "mi-byo"(possible cause of diseases)-diagnosis and the control of aging.
