Methods Groups of Wistar rats underwent total pancreatioduodenal transplantation from allogeneic SD or syngeneic Wistar rats. The grafts were harvested on the posttransplantation day 3,5 and 7 and were used to detect the expression of HSP70 by immunohistochemistry and Western Blotting quantitative methods. The correlation between HSP70 expression and pathological findings was observed. Results The level of HSP70 in the isografts did not change greatly( P 】 0.05); the level of HSP70 in the allografts was increased progressively on the posttransplantation day3, 5 and 7 ( P 【 0.01). There was a significant correlation between HSP70 and pathological score in the allograft group (P 【 0.01, r = 0.934). Conclusion HSP70 involved in pancreas allograft rejection and could be useful for early diagnosis of acute rejection following pancreas transplantation. 8 refs,2 tabs.展开更多
