Abstract:
In this study the course of the expression of the intercellular adhesive molecule(ICAM-1) during the liver transplant has been investigated, additionally the behaviour during a reperfusion injury or a pulsion was examined. Biopsy withdrawals occurred at agreed time during the organ remove, as well as during the transplant. These biopsies were cut, coloured immunhistochemically and judged light-microscopic. The ICAM-1 expression on the vessels, the bile ducts and the Hepatozyten was valued. The course of ICAM-1 during the transplant showed an increase with the vessels, the bile ducts generally shows a extremely low colouring. The Hepatozyten first showed an increase, but after reperfusion appeared a slight decline of the expression. Because ICAM-1 takes 24 hours after stimulation by Zytokine to exprimed, it is to be assigned difficultly to the expression pattern seperate causes. As a graduation for the quantification of a occasionally appeared reperfusion injury, a reperfusion index was defined. The transplant of the patients of the index group III with the biggest reperfusion injury damage showed a substantially shortened functional likelyhood. The patients also showed a raised ICAM-1 expression at the Hepatocytes after reperfusion. It proved no correlation between a raised ICAM-1 expression and a established post surgical histologic repulsion. The duration of the cold ischemia time amounted on an average of 531 minutes. There was no connection between the length of the cold ischemia and an increased ICAM-1 expression.
