Notes:
To determine whether testosterone administration was capable of modifying salivary gland carcinogenesis, female mice were given 1 mg of 9,10-dimethyl-1,2-benzanthracene (DMBA) into the left submandibular gland and then Group 1 mice received 5 mg of testosterone propionate and Group 2 mice received vehicle, olive oil, subcutaneously for 8 weeks. Twelve weeks after the start of the experiment, the weight of the left submandibular gland of the Group 2 mice was greater than that of the Group 1 mice. The incidences of submandibular gland carcinoma in Groups 1 and 2 were 41% (12/29) and 57% (17/30), respectively. Epidermal growth factor (EGF) levels of the left submandibular gland were significantly higher in Group 1 as compared with Group 2. These findings indicate that testosterone increases the production of EGF in the DMBA-injected submandibular gland, but does not promote the development of submandibular gland carcinoma.
