    Abstract:
    The compound N-methyl-amino-2-nitro-4-N', N'-bis(2-hydroxyethyl)-aminobenzene was tested for mutagenic activity in the sex-linked recessive lethal test with Drosophila melanogaster, the induction of chromosomal aberrations and sister-chromatid exchanges (SCEs) with Chinese hamster ovary (CHO) cells in vitro, and the micronucleus test with mouse bone-marrow cells in vivo. Consistently negative results were obtained with the 3 tests. The SCE tests gave positive results with prolonged treatments. It is concluded that reliable decisions about mutagenic activity cannot be based on the induction, in vitro, of SCEs alone.
