| Research Abstract |
We explored the necessary condition of heavy water containing buffer for the use of simple cold preservation. The novel solution appeared to show excellent cytoprotection in various cells, and rat liver and heart, due to the inhibition of cytosolic Ca2+ overload and cytoskeletal breakdown, and stimulation of aerobic respiration. However, these beneficial effects were abolished in liver and kidney preservation and transplantation of dogs, possibly due to the stimulation of intravascular agglutination by PEG. To proceed to the clinical application, customization of PEG concentration should be explored. Further, since the main action of heavy water containing buffer is stimulation of aerobic respiration, we should find better way to provide oxygen without agglutination for the next step.
