title: Shortening of life span caused by administration of 5-bromodeoxyuridine to neonatal rats.
abstract: Newborn rats and adult animals in which liver cell replication had been induced by partial hepatectomy were injected with 5-bromodeoxyuridine (BUdR), and were kept without further treatment for the remainder of their life span. No evidence for carcinogenicity of BUdR was obtained, but a dose-dependent shortening of the life span was observed after administration to neonatal animals.
