| Abstract: | The level of adducts in DNA of rats treated with 2-aminofluorene (2-AF) and 2-acetylaminofluorene (2-AAF) was compared at the times from 1 h till 28 days after injection. The highest amount of DNA adducts was observed 12 h after treatment with 2-AF and 24 h after treatment with 2-AAF, and reached values of about 18 and 21 fmol per micrograms DNA, respectively. Participation of the nonacetylated form, dG-C8-AF, in the total amount of DNA adducts was only slightly greater in rats treated with 2-AF then in those treated with 2-AAF. |
