Abstract
Quantitative autoradiograms were made, in vivo, in European hamsters with the use of [14C]nitrosoheptamethyleneimine (260 muCi/animal; time between administration of nitrosamine and killing of animals, 6 hr). In this species, the lung is the principal target, and radioactivity was found in the Clara cells of the bronchial epithelium and in the nitrosoheptamethyleneimine-induced tumors which derive from these cells. Tumors are not induced in the liver, which can metabolize this compound, and labeling is found principally in the cytoplasm, whereas in the target cells there is a high degree of labeling in both the cytoplasm and the nuclei.
