Abstract:Purpose:To study on the tolerance of renal allograft.Methods:We built the animal model on the specific tolerance of renal allorgaft.The wistar rats were divided into two groups.While the kidney transplantation was performed the donor rats SD spleen cells which were pretreated were injected into portal vein of the recipient rats wistar in experimental group,0.9% normal solution was injected into portal vein in control group.Results:The median survival peroid of the rats was (10.5±2.1) days in control group,(72.2±32.0) days in experimental group (P<0.01).60 days after the transplantation,the rats in the experimental group were transplanted with the skin from the SD rats or Lewis rats.Two weeks later,the SD rat′s skin were survived,the Lewis rat′s skin were dead.Conclusions:It was believed that the intraportal injection of donor spleen cells could induce recipients specific tolerance to renal allograft.
