| Abstract: | "In early period (1-4 day) after exposure to stress, CBA and C57B1/6 female mice excrete (with urine) volatile components (chemosignals) more attractive for intact males of the same strain than excretions of intact females irrespective of the genotype. In later period, attractiveness of excretions of these mice varies in an undulatory way. The difference in attractiveness between compared groups of females disappears within the period of a month after exposure to stress. Comparison of CBA and C57BL/6 strains shows that, within the period of 1-14 days, males prefer syngenic chemosignals (from mice of the same strain). Thus, a post-stress reversion of the genotype-dependent female olfactory attractiveness for males was observed. Such kind of attractiveness substantially differs from that in intact mice, for which the male preference to allogenic chemical signals (female mice of the same genotype) is natural. Features of male preference to chemical signals of females after their exposure to stress were demonstrated in direct comparison with the attractiveness of allogenic female signals. The normal chemosignalization is becoming restored from two to three weeks after the exposure to stress. The biological significance of the described phenomenon is discussed" |
