Estimating the term…
The invention is to provide an information acquisition apparatus for acquiring information relating to at least one of an oxidized form concentration, a reduced form concentration and a ratio of the concentrations of thioredoxin, useful for judging a stress level, and a stress level information acquisition apparatus and a stress level judging method utilizing the same. A reaction by an enzyme or the like catalyzing an redox reaction of thioredoxins is used to measure at least one of an oxidized form concentration, a reduced form concentration and a concentration ratio of thioredoxins, and data of such measurement is used for judging the stress level of a subject person.
An information acquisition apparatus for acquiring information on a concentration of thioredoxins, wherein a concentration of an oxidized form and/or reduced form of thioredoxins in a sample is measured, utilizing an redox reaction of the thioredoxins and distinguishing the oxidized form and the reduced form.
A stress level information acquisition apparatus for acquiring information on a stress level in a subject person of measurement, comprising a stress level judging means which measures a concentration of an oxidized form and/or reduced form of thioredoxins in a sample derived from a subject person of measurement, utilizing an redox reaction of the thioredoxins and distinguishing the oxidized form and the reduced form, and judges a stress level of the subject person of measurement based on the first information selected from the group consisting of the oxidized form concentration, the reduced form concentration and a ratio of the concentrations and on the second information concerning a relation between the first information and a stress level.
A stress level judging method for judging a stress level in a subject person of measurement, comprising a stress level judging step of judging a stress level, based, utilizing an redox reaction of thioredoxins in a sample derived from the subject person of measurement, on at least either of an oxidized form concentration and a reduced form concentration of the thioredoxins and a preset standard.
An enzyme electrode comprising a conductive member and an enzyme, wherein the enzyme catalyzes an redox reaction of thioredoxins.
A thioredoxin concentration measuring method for measuring a concentration of thioredoxins in a sample, which comprises, utilizing an redox reaction of thioredoxins in the sample, to measure at least either of an oxidized form concentration and a reduced form concentration of the thioredoxins in distinguished manner.
