Rapamycin (RAPA) or cyclosporine (CsA) was administered intravenously, daily for 60 days, to rabbits with heterotopic heart transplants. Groups of 5 rabbits were randomly assigned to receive RAPA at 0.05, 0.1, 0.5 or 1.0 mg/kg/day or CsA at either 5.0, 10.0 or 15 mg/kg/day. Drug vehicle and saline controls were also included. Animals were examined daily and the cervical allografts assessed by palpation for viability/rejection. In those animals in which the heart stopped beating, the heart was removed and processed for light microscopic evaluation. The duration of the study was for 60 days at which time the animals were sacrificed and the transplanted heart and native kidneys removed and processed for light microscopic assessment of rejection and drug toxicity respectively. Biochemical and functional parameters in these animals were previously reported (Transplantation 5: 340-345, 1993). Animals that rejected their grafts were maintained on the drug until the endpoint of the study to assess toxicity in the native kidneys. The rejected hearts from these animals were also harvested for microscopic evaluation. The results of the study revealed that heart rejection in drug treated animals was significantly lower than in corresponding controls but not different among the various drug treated groups. In the kidney, there were no differences in glomerular tuft area or tuft volume density amongst drug-treated or control animals. In contrast, tubule atrophy and interstitial fibrosis were markedly greater in CsA-treated vs RAPA-treated animals (X2 5.00, p < 0.02).(ABSTRACT TRUNCATED AT 250 WORDS)
