title: [Characteristics of the mutagenic and toxic effects of ethylene imine and its oligomers. Comparative study in the automated SOS-chromotest system and in standard bacterial test systems].
abstract: Raising total positive charge of a chemical mutagen does increase its local concentration in the area of biological target-DNA, and, as a consequence, causes increase in the rate of interaction of a mutagen with the target. Experimental evidence of this idea has been obtained in three test systems: the Ames test, Trp+ reversions in Escherichia coli WP2 and in the automated "SOS-chromotest" system with E. coli PQ 37 ("Labsystems", Finland).
