[Attraktive and aversive for intact individuals volatile excretion of male mice induced a thymus dependent antigen].

Immunization of male mice of the CBA and C57BL/6J strains with sheep red blood cells (SRBC) induce excretion of urinary volatile components (VC), modifying the behavioral reactions of intact males CBA strain. In early times after injection of 1 x 10(8) SRBC per mouse results in secretion of attractive VC, whereas injection of 1 x 10(9) cells per mice induces secretion of aversive VC. Regular for normal and the observed also in the early stages of attraction of intact males CBA to VC immunized syngeneic males CBA (relatively VC immunized with allogeneic C57BL/6) was lost from 3 to 14th day after the introduction of SRBC in the dose of 1 x 10(8) cells/mice and with the 9th on the 14th day after the introduction of SRBC in the dose of 1 x 10(9). The biological significance of the antigen induced chemosignaling in animals is discussed.
