| Outline of Final Research Achievements |
We produced the duodeno-esophageal reflux (DER) model and the gastroduodeno-esophageal reflux (GDER) model surgically. Survival rate after stabilization of surgical procedure was 63% in DER group and 58% in GDER group, respectively. The production procedure of mouse reflux esophagitis model was established.
The incidence of Barrett's epithelium was 71% in DER group and 83% in GDER group, respectively. The incidence of esophageal adenocarcinoma was 29% in DER group and 33% in GDER group in 40 weeks after surgery. The oncogenic rate was low and the histological change was mild in mouse model compared with rat models we have investigated.
Barrett epithelium was observed in 69% and esophageal adenocarcinoma was in 15% of mouse in the GDER group which were dietary administrated parthenolide, the NF-κB inhibitor. Chemopreventive effect of NF-κB inhibition in esophageal carcinogenesis caused by chronic inflammation was observed.
