Outline of Final Research Achievements |
We developed a prototype of a recirculating device for measuring acetaldehyde in esophageal tissue, and then we measured the in vivo acetaldehyde concentration rate of esophageal tissue by using living porcine model. However, we could not measure this rate because it is difficult to keep a recirculating needle into the esophageal epithelium due to interference between the tube of this device and endoscope which was used for entering the recirculating needle into the esophageal epithelium. However, we revealed that it is possible to measure acetaldehyde concentration rate of esophageal and gastric tissue by endoscopic biopsy, and acquired the preliminary data for the future trial.
