title: Carcinogenicity of N-nitroso-ethylenethiourea in female mice.
abstract: The nitrosation product of ethylenethiourea (ETU), N-nitroso-ETU, was tested for tumorigenicity in female ICR mice. Ten weekly oral administrations of this compound (0.66-2.64 mg/dose) caused apparently dose-dependent increases in the number of mice with pulmonary and lymphocytic neoplasms.
