METHOD FOR QUANTITATIVELY MEASURING ACID DEGREE IN STOMACH BY USING 13C CARBONATE

摘要

PROBLEM TO BE SOLVED: To provide a method for measuring an acid degree in the stomach of a mammal by using aC labeling carbonate compound.SOLUTION: The method for measuring the acid degree in the stomach of the mammal according to the present invention includes the steps of: (1) acquiring an expired air expired by a mammal to be tested at an arbitrary time point (t) within 30 minutes after being orally administered with a predetermined dose of theC labelling carbonate compound; (2) using the expired air obtained in the step (1) as a test sample to obtain a ratio of the amount ofCOwith respect to the amount ofCOin the expired air, to thereby calculate behavior of theCO(measuredCObehavior); (3) comparing the measuredCObehavior obtained in the step (2) with behavior (referenceCObehavior) of theCOcorresponding thereto, which has been previously obtained for a mammal to be compared (comparison mammal); and (4) determining the acid degree in the stomach of the mammal to be tested on the basis of a difference, obtained in the step (3), between the referenceCObehavior and the measuredCObehavior.SELECTED DRAWING: None
