Postirradiation volatile secretions of mice: syngeneic and allogeneic immune and behavioral effects.

The immune response in immunologically and olfactorily high- and low-reactive CBA and C57Bl/6 mice is almost similarly decreased after exposure to volatile secretions of syngeneic animals exposed to ionizing radiation in a dose of 4 Gy. In the preference/avoidance test intact animals prefer secretions of irradiated syngeneic and allogeneic animals to those of intact animals, while without irradiation animals of both strains prefer syngeneic secretions. C57Bl/6 mice differ from CBA animals by lower sensitivity.
