ABSTRACT

Objective To study the effect of cold prolonged storage of rat livers with self-designed HYS solution on hepatic biochemical functions.Methods The preservation effect of HYD solution with that of UW solution and Lactate Ringer's solution(LR)was compared by using isolated perfused rat liver model.Results All the indices of hepatic biochemical functions in HYD group were better than in LR group for 12 h storage.The contents of ATP,TAN and AEC in HYD group were significantly higher than in Uw group for 36 h storage(P＜0.05).pH in HYD group was markedly higher than in UW group for 30 or 36 h storage(P＜0.05).The hydrolytic activities of H+-ATP ase in hepatic mitochondria and bile production were mildly higher in HYD group than in UW group(P＞0.05).No significant difference in AST,ALT and LDH in the effluent were found between HYD group and UW group(P＞0.05).Conclusions The effect of 12 h storage of rat livers with HYD solution might be better than with LR solution.The effect of HYD solution is similar to that of UW solution within 36 h storage.However.HYD solution is slightly superior to UW solution in some aspects.such aS improvement of energy metabolism during cold storage and reperfusion,prevention of intracellular acidosis.bile production and perfusion of liver in situ.
