IMMUNOSUPPRESSION WITH FR 900506 FOR CANINE KIDNEY AND LIVER TRANSPLANTATION.

Abstract

The immunosuppressive effects of FR 900506 were investigated for one month after canine kidney and liver transplantation. Eight untreated kidney recipients lived for 8 to 19 days, mean 12.1. In contrast, the one month survival of dogs given FR 900506 in daily oral doses of 0.5, 1.0, and 1.5 mg/kg was 2/6, 3/6, and 4/6 respectively. The one month survival of liver recipients was 4/5 compared to one month survival of 1/8 in historical untreated controls. There was no evidence from biochemical tests of hepatotoxicity or nephrotoxicity.
