摘要： A diagnostic agent for being sprinkled to the inner wall of a gastrointestine in endoscopic observation, comprising an acidic aqueous solution of pH 1 to 5 containing a colorant and also containing at least one acid selected from the group consisting of a carboxylic acid, hydrochloric acid, sulfuric acid and phosphoric acid. By sprinkling such a diagnostic agent to the inner wall of a gastrointestine in endoscopic observation, it is possible to clearly observe a lesion which is difficult to be determined. In particular, it is suitable for observing lesions having cancer cells in the stomach or the Barrett's esophagus.

摘要： A method of conducting an endoscopic observation of an inner wall of a gastrointestine by applying a diagnostic agent to the inner wall of the gastrointestine, the diagnostic agent being an acidic aqueous solution of pH 1 to 5 containing a colorant, and conducting the endoscopic observation of the inner wall. The acidic aqueous solution can contain at least one acid selected from a carboxylic acid, hydrochloric acid, sulfuric acid and phosphoric acid. By applying the diagnostic agent to the inner wall of the gastrointestine in the endoscopic observation, it is possible to clearly observe a lesion which is difficult to be determined. In particular, the method can be used for observing lesions having cancer cells in the stomach or the Barrett's esophagus.
