| Abstract: | Effect of snuff extract (SE) on cell proliferation as measured by 3H thymidine (TdR) uptake, induction of ornithine decarboxylase (ODC) and aryl hydrocarbon hydroxylase (AHH) was studied in primary embryonal mouse tongue cultures. Cultures treated with SE in combination with 7,12-dimethylbenz(a)anthracene (DMBA) showed inhibition of cell proliferation and decrease of ODC and AHH activities, compared to control, DMBA, and DMBA + 12-O-tetradecanoylphorbol 13-acetate treated cultures. |
