[Shigella antigens in early pathogenetic therapy of experimental acute radiation sickness].

In experiments on gamma-irradiated hamsters it is shown that antigens, obtained from Sh. flexneri and sonnei by the sparing method, have a radioprotective therapeutic action. The antigens exhibit the immunostimulating activity which is perhaps one of the aspects of the mechanism involved in the formation of resistance to infectious complications in irradiated animals and of the favourable radioprotective effect.
