ABSTRACT
OBJECTIVE:
To study the effect of Poria cocos (Pcs) in preventing acute rejection of rats after renal transplantation and its mechanism.METHODS:
Rat orthotopic renal transplantation model was performed with Wistar rat as donor and SD rat as donee. All donees were divided into 4 groups, 10 in each group, before transplantation. They were treated respectively with normal saline 5 mL x kg(-1) x d(-1) (A), Pcs 25 mg x kg(-1) x d(-1) (B), Pcs 50 mg x kg(-1) x d(-1) (C) and ciclosporin A (CsA) 5 mg x kg(-1) x d(-1) (D) by intragastric administration. The renal allograft survival time (ST) was recorded, and the serum levels of creatinine (SCr), interleukin-2 (IL-2), gamma-interferon (gamma-IFN), CD4+, CD8+ lymphocytes percentage, CD4+/CD8+ ratio, as well as the pathologic changes were observed one week after transplantation.RESULTS:
ST of the renal graft in Groups C and D was significantly longer with pathologic change evidently less than those in Groups A and B (P<0.01), and the ST in Group C was shorter that in Group D (P<0.05). Changes of renal function and urine volume were identified to the pathological change of graft, the initiating time of renal dysfunction was later in Groups C and D than that in Groups A and B. Serum levels of IL-2, IFN-gamma and CD4+ percentage in Group C were significantly lower than those in Groups A and B, but higher than those in Group D respectively (P<0.05 or P<0.01), while CD8+ percentage in Group C was significantly lower than that in Group A (P<0.05), but insignificantly different to that in Groups B and D (P>0.05).CONCLUSION:
Pcs shows good dosage-dependent effect in suppressing acute rejection of renal transplantation, but the effect is inferior to that of CsA.
