Abstract: The effects of similar doses of the values of common external irradiation (0.19 Gy/4 hours and 0.24 Gy/6 months) at single-strand DNA breaks and the level of the hydrogen bonds in this molecule in different cell types (lymphocytes, hepatocytes and splenocytes) linear mice CC57W/mv are discussed. Mice were exposed to γ-fields produced by "hot" particles of emergency 4-th Chernobyl Unit containing the same radionuclides in the proportions. The possibility of leveling the radiation effects using complex biopolymers from Fomes Fomentarius was shown. The ability of melanin-glucan complex to directly counteract the fragmentation of DNA in a model system with lambda phage this macromolecule oxidation products of benzidine and neutralize mutagenic effect in Salmonella typhimurium strains in the classical Ames test was studied
Keywords: ionizing radiation, acute and chronic effects, DNA, fungal biopolymers.
