AIM To investigate the effect of recipient kidney function by CsA coadministration Ber used to induce immune tolerance
in rats of allogenic cardiac
transplantation. METHODS The authors established the SD to Wistar rats
heterotopic cardiac transplantation model by Onos methods.Observe the cardiac allograft survival and levels of BUN and Cr in the recipients plasma. The recipients were classified into 5 groups randomly after heterotopic cardiac transplantation were performed. Group A (Wistar to Wistar)): Received placebo intraperitoneal injected for 21 days; Group B (SD to Wistar): Saline intraperitoneal injected for 21 days; Group C (SD to Wistar):CsA 2 mg·kg -1 ·d -1 intraperitoneal injected for 21 days; Group D(SD to Wistar):Ber 16 mg·kg -1 ·d -1 gastrointubation for 21 days; Group E(SD to Wistar): Ber 16 mg·kg -1 ·d -1 gastrointubation coadministration CsA 2 mg·kg -1 ·d -1 ip for 21 days. RESULTS The levels of BUN and Cr in recipint plasma is lower evidently compare with the group with CsA ip simply. CONCLUSION Ber can reduce the renal toxicity in recipients by CsA which was intraperitoneal injected (ip) over a long period time.
