这项工作的长期目标是开发一种更好的方法,
保存人类肝脏以备移植这样做的后果
将是:为死于终末期肝脏的患者提供更多的肝脏
疾病,移植肝脏的数量减少,
原发性无功能或移植物功能延迟,功能增加
对于国家(或国际)共享尸体肝脏,
肝移植的费用,减少需要
再次移植和患者的住院时间(ICU)。
目前,威斯康星州大学(UW)的解决方案是标准
用于肝脏保存的保存液。我们将使用此解决方案,
开发改进的保存溶液和方法的基础
保存(简单冷藏和连续机器灌注)。的

英文摘要
The long range objective of this work is to develop a better method to
preserve the human liver for transplantation. The consequences of this
would be: more livers available for patients dying from end stage liver
diseases, a decrease in the number of transplanted livers that develop
primary non-function or delayed graft function, increase in capabilities
for national (or international) sharing of cadaveric livers, a decrease in
the cost of liver transplantation by reducing the need for
retransplantation and the length of hospital (ICU) stay of the patient.
Currently, the University of Wisconsin (UW) solution is the standard
preservation solution for liver preservation. We will use this solution as
the basis for developing improved preservation solutions and methods of
preservation (simple cold storage and continuous machine perfusion). The
specific aims of this study are to gain an understanding of the mechanisms
of cellular injury caused by hypothermic storage of the liver and with this
knowledge develop improved preservation methods. We will study the
mechanisms of hypothermic injury using a rat hepatocyte and rabbit liver
isolated perfusion model. We will study how precursors of ATP and
glutathione synthesis affect preservation, the role of calcium and
phospholipid lipases in preservation injury and how various drugs affect
the preservation of the liver. Additionally, we will gain insight into the
mechanism of preservation injury by investigating the importance of the
various components of the UW solution and how the addition of different
drugs and metabolites to the UW solution affect the quality and duration of
liver preservation. We will determine how preservation affects the energy
generating capabilities of the liver and how oxygen free radical scavengers
affect preservation quality. We will also study how donor factors affect
liver preservation, specifically the nutritional status of the donor.
Methods that improve liver cell metabolism and liver functions will be
tested in the dog orthotopic transplant model to determine if these methods
translate to a more clinically relevant model of liver preservation.
Methods that improve liver preservation in the laboratory will be used for
human liver preservation.
