Abstract:
Objective To establish the model of abdominal heterotopic heart transplantation and grope steady operation methods.Methods The heart transplantation was performed in the control group(group A) and experiment group(group B) with 30 rats in each group.Another 30 animals not performed the operation were as the blank group(group C).During the procurement of the donor heart saline solution containing heparitin was injected into the inferior vena cava of liver.At the same time abdominal aorta was transected.Then heart was perfused until it stopped.The activity of superoxide dismutase(SOD) and content of malondialdehyde(MDA) in blood was measured after transplantation.Results The total perfusion time of the graft was shortened within 2 min and hot ischemia time was shortened within 25 s in the group B.The activity of SOD and content of MDA between two groups was significantly different(P<0.05).Conclusion The perfusing method improved with new technique is quicker and more effective than the traditional one and results in the successful rate improvement.
