title: [Comparative study of the biological properties of various bacterial polysaccharides].
abstract: It was shown that different polysaccharides markedly vary in their toxicity, exert a radioprotective effect when administered both 24 h and 1-4 h before irradiation, enhance and prolong the radioprotective action of S-containing radioprotective agents, and inhibit DNA synthesis in bone marrow which, in all appearance, plays a certain role in the mechanism of their radioprotective action.
