Abstract
AIM: To develop an experimental model of islet allotran-splantation in diabetic rats and to determine the positive or adverse effects of MMF as a single agent.
METHODS: Thirty-six male Wistar rats and 18 male Lewis rats were used as recipients and donors respectively. Diabetes was induced by the use of streptozotocin (60 mg/kg) intraperitoneally. Unpurified islets were isolated using the collagenase digestion technique and transplanted into the splenic parenchyma. The recipients were randomly assigned to one of the following three groups: group A (control group) had no immunosuppression; group B received cyclosporine (CsA) (5 mg/kg); group C received mycophenolate mofetil (MMF) (20 mg/kg). The animals were killed on the 12th d. Blood and grafted tissues were obtained for laboratory and histological assessment.
RESULTS: Median allograft survival was significantly higher in the two therapy groups than that in the controls (10 and 12 d for CsA and MMF respectively vs 0 d for the control group, P<0.01). No difference in allograft survival between the CsA and MMF groups was found. However, MMF had less renal and hepatic toxicity and allowed weight gain.
CONCLUSION: Monotherapy with MMF for immunosu-ppression was safe in an experimental model of islet allotransplantation and was equally effective with cyclosporine, with less toxicity.
