Empirical study on effect of emodin on acute rejection after orthotopic liver transplantation in rats / 中华中医药杂志

ABSTRACT

Objective:To evaluate the effect of emodin on acute rejection after orthotopic liver transplantation(OLT) in rats.Methods:The LEW→BN OLT models were established.A total of 45 rats were divided randomly and equally into 3 groupsgroup A was treated with normal saline at dose of 0.5 ml/d intraperitoneally from 1st day to 8th day after operation;Group B,CsA at dose of 10.0 mg?kg-1?d-1;Group C,emodin at dose of 50.0 mg?kg-1?d-1.8 days after operation,6 recipients of each groups were killed for confirming rejection-active index(RAI) and hepatocellular apoptosis index(AI) by observing the pathologic change of transplanted liver in recipients.The other recipients were raised for observing the survival time.Results:Respectively,the survival time(days) of group A,B,C was 9.50?1.64,21.57?2.15,21.29?2.21.The survival time of group B,C was significantly longer than that of group A(P0.05).Respectively,the RAI of group A,B,C was 7.67?0.9,5.17?0.40,5.83?0.75 and the AI of group A,B,C was 35.83?2.32,15.83?1.33,16.50?2.35.The RAI and AI of group B,C was significantly lower than that of group A(P0.05).Conclusion:Emodin can reduce the hepatocellular apoptosis and suppress the acute rejection after OLT in rats.
