[Effects of "pheromone-like" pyrazine-containing substances on stability of genetic apparatus in bone marrow cells of the male house mouse (Mus musculus L.)].

There was studied effect of female house mouse pheromone 2,5-dimethylpyrazine and other pyrazine-containing substances on the genetic apparatus stability of dividing bone marrow cells of male mice of the strain CBA. Differences in action of the used chemosignals are revealed. Role of the method of action on induction of analyzed mitotic aberrations is shown. Spectrum of the aberrations is analyzed. Dependence of cytogenetic activity of the used substances on their structural peculiarities and significance of the revealed effects are discussed.
