Fluoroquinolone antiinfective drugs exhibit phototoxic, photogenotoxic, and photocarcinogenic activities in experimental systems which may be interrelated. Clinafloxacin (CLX), a new fluoroquinolone, is a potent antiinfective agent being developed fo

In this article, an integrated in vivo genotoxicity testing philosophy and a practical approach, as applied to pharmaceuticals, are described. Recently, there has been an effort to integrate the rodent (primarily rat) micronucleus assay with routine

Acute, subacute, and chronic toxicity studies, carcinogenicity bioassays, and reproductive and genetic toxicology studies were performed with quinapril, an ACE inhibitor used in the treatment of hypertension. Acute toxicity is minimal in rodents, and

Apoptosis or programmed cell death is a biological event that is biochemically and morphologically distinct from cellular necrosis. Nonetheless, its relationship has not been studied in terms of a cytogenetic endpoint such as micronucleus formation.

While HMG-CoA reductase inhibitors such as fluvastatin, lovastatin, pravastatin and simvastatin demonstrate lack of in vitro and in vivo mutagenicity and clastogenicity in bacterial and mammalian cells, long term rodent carcinogenicity studies result

Bone marrow and spleen toxicity, clastogenicity and aneugenicity were analyzed in the CD1 mouse using an antikinetochore antibody (AKA) procedure (Krishna et al., Mutation Res., 282, 159–169, 1992). Further, to verify the fluorescence micronucleus

The genotoxicity of pirmenol was tested in the E. coli and S. typhimurium mutagenesis assay, an in vitro mammalian cell chromosome-aberration assay and an in vivo mouse micronucleus assay. The E. coli tester strain WP2s was exposed to concentrations

An improved antikinetochore antibody technique was established in the mouse micronucleus assay to simultaneously evaluate toxicity, clastogenicity and aneugenicity induced by various test agents. The procedure involved the use of cellulose column fra
