Abstract/OtherAbstract:
Following exposure of rats to the arylamine carcinogen 2-aminofluorene, DNA-carcinogen adducts were found in the target tissues of the liver and bladder, and also in circulating leucocytes. This work investigated how paeonol affects arylamine (2-aminofluorene and p-aminobenzoic acid) acetylations in rat leucocytes. Evidence is presented showing that rat mononuclear leucocytes are capable of acetylating 2-aminofluorene and p-aminobenzoic acid. Paeonol promoted 2-aminofluorene and p-aminobenzoic acid acetylation. Cultured lymphocytes produced about twice as much N-acetyl-2-aminofluorene from 2-aminofluorene and 2.2-fold as much N-acetyl-p-aminobenzoic acid from p-aminobenzoic acid as monocytes. After cotreatment with paeonol, the lymphocyte and monocyte cultures indicated that paeonol did increase 2-aminofluorene and p-aminobenzoic acid acetylations.
