Abstract:
Objective:To establish the acute rejection model of orthotopic liver transplantation in rat(ROLT) and observe the basic pathophysiologic changes of acute rejection.Methods:The rats were randomly divided into three groups:control group,isotransplantation group(LEW-LEW),and allotransplantation group(LEW-BN).Recipients were sacrificed on 3,5,7,and 10 days postoperatively and liver tissues and blood samples were collected.Recipient survival rate,histopathological and ultrastructural characteristics were observed.ALT,TBIL,and Alb were measured with automatic biochemical analyser.IL-2 content in serum was assayed by ELISA.Results:There was no rejection in isotransplantation from Lewis to Lewis rat resulted and 14-day survival rate reached 100%.The IL-2 concentration in serum was at normal level.On the contrary,all recipients in allotransplantation group from LEW to BN rat died among 14 days postoperatively,and hepatic histological examination showed typical acute rejection on 7 days.Liver function was severely impaired,which was indicated by significant increase of ALT and TBIL levels and apparent decrease of Alb level.The IL-2 concentration in serum was continuously increased and reached its peak value on 7 days postoperatively.Conclusion:An acute rejection experimental model of liver transplantation in rat could be stably established using Lewis rat as donor and BN rat as recipient.
