ABSTRACT
Objective To study the immune protective effects of liver graft on intestinal graft in simultaneous liver/small bowel transplantation. Method Rat models(Wistar to SD) of liver/small bowel transplantation(LSBTx),single liver transplantation(LTx)and single small bowel transplantation(SBTx) were established respectively. Twelve recipients from each group were used to determine survival time. Six recipients from each group were sacrificed for liver and/or small bowel biopsy at posttransplantation day 5,7 and 14,respectively. Rejections were detected by histopathology and mRNA expression of IL-2,IL-4,perforin and granzyme B in grafts by semi-quantitative reverse transcript PCR. Result The survival time of LSBTx recipients was (27.83?4.47) d,much longer than SBTx recipients (11.58?3.26) d,but was similar to LTx recipients (28.92?2.39) d. Allograft rejections of intestinal graft in LSBTx group were milder than that in STBx group,accompanied by down-regulated mRNA expression of perforin and granzyme B. Conclusion Simultaneous liver/small bowel transplantation in rats provides immune protection on intestinal graft.
