title: [Effect of testosterone propionate on the induction by 1,2-dimethylhydrazine of angiosarcomas of the renal capsule in castrated mice].
abstract: Administration of 1,2-dimethylhydrazine (DMH) produced 83% (15/18) of renal capsule angiosarcomas in CBA mice. Castration that preceded the DMH-treatment reduced tumor incidence to 7% (2/29). Simultaneous administration of DMH and testosterone propionate (TP) to castrated males restored the tumor frequency (100%, 24/24). Castrated males that received TP after the cessation of the DMH treatment developed tumors in 10% (3/31). Combined treatment of castrated females with DMH and TP resulted in the development of angiosarcomas in 92% animals (22/24). It is concluded that TP enhances the stage of sarcomogenesis initiation induced by DMH.
