THE IMMUNOSUPPRESSIVE EFFECTS OF FR 900506 IN RATS RECEIVING HETEROTOPIC CARDIAC ALLOGRAFTS

Surg Res Commun. 1987:1:325-331.

Abstract

The immunosuppressive effects of FR 900506 were studied in Lewis rats given ACI heterotopic heart allografts. Intramuscular doses of 0.02 mg/kg daily for 2 weeks extended graft survival slightly, and with doses up to 1.28 mg/kg for 2 weeks, there is long-term graft survival. If only 3 daily doses were given starting on day 4 after transplantation, graft survival for almost 3 months was accomplished in 4 of 6 animals who still bear functioning hearts.
