[Radioprotective effect of Corynebacterium michiganense polysaccharide]

Antiradiation activity of polysaccharide isolated from phytopathogenic coryneform bacteria Corynebacterium michiganense has been established. It is shown that the introduction of polysaccharide immediately or 2 h after irradiation with the lethal dose promotes maximum survivability of experimental animals (30 and 20%, respectively).
