Abstract:
Objective．To investigate the effects of cold preservation on rat fatty liver．Methods．We observed the changes of portal perfusion pressure，endothelin-1，enzymes relesase in the effluent and mortality of sinusoid lining cell after 0h，6h，or 12h preservation respectively and a subsequent 30 min reperfusion in rat fatty liver groups and control groups by using isolated perfused rat liver model．And we compared fatty liver groups with control groups by these indices．Results．There was no obvious difference between mildly fatty liver group and control group after long time（12h）preservation，between moderately fatty liver group and control group after short time（6h）preservation，between severely fatty liver group and control group without preservation（0h），while preservation reperfusion injury was more severe in moderately fatty liver group than in control group after long time（12h）preservation and in severely fatty liver group than in control group after short time（6h）preservation．Conclusions．The authors suggested that a mildly fatty liver donor could be used in the same way as nonfatty liver and a moderately fatty liver donor could be used depending on the time of preservation and the balance of the emergent needs of recipient and donor organ supply，while severely fatty liver donor should be discarded without hesitation．
