title: Effects of isoproterenol on chemical carcinogenesis with DMBA in mouse salivary glands.
abstract: Histopathological studies were conducted on experimental carcinogenesis in mouse salivary glands using D L-isoproterenol hydochloride (isoproterenol) and 9 10-dimethyl-1 2-benzanthracene (DMBA). DMBA was administered once at 1 mg/0.02 ml in olive oil to the salivary glands, and isoproterenol was injected intraperitoneally at 1 mg/0.05 ml saline solution three times a week for 2 weeks at different periods during the oncogenic process. Salivary glands treated with carcinogen showed a relatively constant sequence of changes and developed epithelial and mesenchymal tumors irrespective of isoproterenol administration. Isoproterenol did not influence the development of another type of tumor; however, it did retard the oncogenic processes.
