【Abstract】Objective  To investigate the injury of calcium on the liver. Methods  By using collagenase-containing solution to perfuse the rat livers, the rat liver suspension with different viability was prepared, preserved hypothermically, and the cytosolic calcium comcentration was detected with Fura2/AM. Results  ① The concentration of cytosolic calcium after 2-hour storage: Experiment group 1(viability 5%) (1055.0±30.79) nmol/L, experiment group 2(viability 10%) (853.0±20.42) nmol/L, experiment group 3(viability 30%) (616.0±13.20) nmol/L, experiment group 4(viability 50%) (562.0 ±26.06) nmol/L, experiment group 5(viability 70%-80%) (318.0±13.01) nmol/L, experiment group 6(viability 90%) (114.6±6.11) nmol/L. ②The concentration of cytosolic calcium after 24hour storage: Experiment group A(viability 10%) (1704.0±70.11) nmol/L, experiment group B(viability 50%) (1125.0±23.22) nmol/L. The results showed that the lower was the viability, the higher was the cytosolic calcium concentration.With the same viability the cytosolic calcium concentration elevated more than two times higher than the original concentration with the time lengthened. Conclusion  Calcium overload is one of the main factors which attribute to the ischemiareperfusion injury of the hepatocytes.
