Outline of Final Research Achievements

With the development of transplantation medicine in recent years, various organ preservation methods have been developed one after another, and further technological development is still in progress. Applicants have developed a new vessel preservation method using high-pressure medical gas (oxygen (O2) 1.5 atm and carbon monoxide (CO) 2 atm) to preserve the rat heart for 24 hours and perform the same function as immediately after excision. It was also clarified that this preservation method is also effective for lung preservation in dogs. In addition, this preservation method has been shown to have a significant effect on the ATP supply of cells and reduce oxidative stress.

Academic Significance and Societal Importance of the Research Achievements

近年の移植医療の発展に伴い、様々な臓器保存法が次々に開発され、現在も更なる技術開発が進んでいる。また、メディカルガスとして臓器や細胞を保護する効果があるガスが多数報告され、臓器保存への応用が期待されている。我々が開発した高圧メディカルガス保存法(酸素(O2)1.5atmと一酸化炭素(CO)2atm)は、保存された臓器の質を維持し、臨床現場においても実用的であると考えられる。
