title: Carcinogenicity of 1-oxopropylpropylnitrosamine (N-nitroso-N-propyl-proprionamide) in Syrian hamsters.
abstract: The effect of 1-oxopropylpropylnitrosamine (1-OPPN) was examined in Syrian hamsters. The subcutaneous (s.c.) LD50 was 308 mg/kg b.w. Animals treated s.c. once with a high dose of 1-OPPN had subcutaneous sarcomas and vaginal papillomas. Weekly s.c. injections for life led to high incidences of sarcomas at the injection site. In addition, 1-OPPN had a systemic effect. Neoplasms developed in the nasal cavity, larynx, trachea, lungs forestomach, and vagina. The results are discussed in connection with those found with other DPN derivatives substituted in the alpha-position.
