MEANS FOR DETECTING OXYGEN FREE RADICALS IN HUMAN BODY

摘要

The present invention relates to a means for detecting oxygen free radicals in the human body, which quantitatively detects the amount of oxygen free radicals remaining in the body by applying urine to a detection paper, and is characterized by providing a means for detecting oxygen free radicals in the human body, which detects the amount of oxygen free radicals by submerging into urine a test strip, on which has been applied a color indicating agent that changes color by reacting with malondialdehyde and to which has been coupled a support stick, and observing color change. The test strip uses 1,3-diethyl-2-thiobarbituric acid (TBA) as a color indicating agent, and is formed by submerging the test strip into a first solution, which is prepared by mixing 10 to 30% of citric acid and 20 to 30% of trisodium citrate with distilled water, drying the test strip at approximately 50 to 60°C for 20 to 30 minutes, submerging the test strip again into a second solution, which is prepared by mixing 2 to 3 % of TBA that is the color indicating agent and 2 to 5% of polyvinylpyrrolidone (PVP) that is a polymer while using ethyl alcohol as a solvent, and then drying the test strip. The present invention can affordably and simply identify oxygen free radicals, because the test strip changes color when simply wetted with urine and the test does not require professional manpower or expensive equipment. Also, the present invention enables simple testing regardless of time and space since a specific facility is unnecessary for the test, thereby providing another advantage of general usage.
