Abstract
The biological effect of N-nitroso-N-methyl-N-dodecylamine (NMDA) was examined in Syrian hamsters as part of a comparative study. Data obtained show that after intragastric administration of NMDA, the urinary bladder was the main target organ for the carcinogenic effect. Transitional cell neoplasms developed and a positive dose response relationship was observed. Lung tumors occurred only in female hamsters, whereas males more frequently showed neoplasms of the nasal cavity and digestive tract.
