Abstract Consumption of mustard oil adulterated with argemone oil leads to a clinical condition, commonly referred to as "Epidemic Dropsy." Since in vitro studies have shown that sanguinarine, an active benzophenanthridine alkaloid of argemone oil, intercalates DNA molecule, the in vivo clastogenic and DNA damaging potential of argemone oil was investigated in mice. Swiss albino mice were intraperitoneally administered 0.5, 1.0, 2.0 and 4.0 ml/kg body wt. of argemone oil to analyze chromosome aberrations and micronucleus test, while 0.25, 0.5, 1.0 and 2.0 ml/kg body wt. were given for alkaline comet assay. The frequencies of chromosomal aberrations and micronucleated erythrocytes formation in mouse bone marrow cells increased in a dose-dependent manner following argemone oil treatment. However, significant induction in chromosomal aberrations (83\%) and micronucleated erythrocytes formation (261\%) were observed at a minimum dose of 1.0 ml/kg. The results of comet assay revealed DNA damage in blood, bone marrow and liver cells following argemone oil treatment. Olive tail moment (OTM) and tail DNA showed significant increase in bone marrow (35-44\%) and blood cells (25-40\%) even at a dose of 0.25 ml/kg body wt. of argemone oil. In liver cells, OTM was significantly increased (20\%) at a dose of 0.25 ml/kg, while all the comet parameters including OTM, tail length and tail DNA showed significant increase (31-101\%) at a dose of 0.5 ml/kg. These results clearly suggest that single exposure of argemone oil even at low doses produces genotoxic effects in mice. (c) 2004 Wiley-Liss, Inc.
