| Outline of Final Research Achievements |
The transplantation medicine has been established as a common approach to therapy. However, it is difficult to storage the small intestine and survival rate after transplantation is lower than other organs. The limitation time of storage for isolated small intestine is very short (6 to 8 hours), because of the weakness against ischemia. Therefore, the novel methods for avoiding the ischemia injury are desired.
Recently, we developed a new organ preservation method using mixed high pressure gas of carbon monoxide and oxygen. The aim of this study is to preserve the small intestine in this method. In the long-term (24h) preservation of rat and dog's small intestine, although the part of mucosa was dropped, active peristaltic movement was confirmed. These results indicated that the preservation method using mixed high pressure gas is useful for the small intestine regardless of the size.
