Abstract:
Streptozotocin-diabetic isogenous Brown-Norway (BN) rats received heterotopic Wistar-Furth (WF X BN) F1 heart transplants. The functional graft survival time after different duration of diabetes and during insulin-treated diabetes was recorded. Some diabetic rats were challenged with sheep red cells, and their spleens were used in PHA stimulation and plaque-forming assays. Prolongation in heart transplant survival was found to be independent of the duration of diabetes. The prolongation disappeared promptly when insulin was administered to the diabetic rats. A depression of cellular immunoresponsiveness as measured by PHA stimulation assay was recorded during diabetes. Valid results were not obtained in the plaque-forming assay.
