title: Induction of in vivo sister chromatid exchanges by arecaidine, a betel nut alkaloid, in mouse bone-marrow cells.
abstract: The genotoxicity of arecaidine, an alkaloid of betel nut, was studied on mouse bone marrow cells in vivo by sister chromatid exchange (SCE) method. Arecaidine was administered intraperitoneally to mice at the dose levels of 2.5 mg, 5 mg and 7.5 mg to each mouse weighing 25 +/- 1 g for 5, 10 and 15 days. Significant increase in the number of SCEs was observed in the treated groups, and this increase, although dose-dependent, was not dependent upon the duration of exposure.
