ABSTRACT
Objective To explore the significance of complement split product C4d in monitoring chronic rejection of renal allografts in rats.Methods Healthy closed population rats were used as donors and SD rats as recipients. The Wistar to SD model of graft rejection was developed. All the 42 recipients were randomly divided into 2 groups group A receiving nothing except CsA (5mg?kg~ -1 ? d~ -1 ) in the first 10 days after operation, and group B receiving MMF (10 mg/kg) and CsA after operation. On the 3rd, 5th and 10th week, all the allografts were tested by light microscopy and immunofluorescence. Pathological changes of the kidneys and the expression of C4d in allograft tissue were observed.Results From the 3rd week, the rats in group A showed light pathological changes of chronic rejection and they became more and more obvious as time increased. Pathological changes occurred in group B at the 5th week and lighter than in group A. At the same time, C4d deposition in PTC was obviously observed on the 3rd week in group A, and on the 10th week C4d widespread deposition in allografts.Conclusion The deposition of complement split product C4d in allografts appears earlier than pathological change of chronic rejection, which can be regarded as a significant indicator to predict chronic rejection of renal allografts.
