BIOLOGICAL EFFECTS OF IONIZING RADIATION ON MOLECULAR LEVEL
Under the sponsorship of the International Agency for Atomic Energy in Vienna, a scientific symposium was convened by the Czechoslovak Academy of Sciences and the Czechoslovak Atomic Commission on July 2 to 6 in Brno to deal with the radiation effects on albumins and nucleic acids. Papers on the following subjects were presented in six sessions: Drasil, Czechoslovakia, reported on processes in irradiated tumor cells; Belyayeva, USSR, studied the changes in albumins during first post-irradiation phases; Kanazir, Yugoslavia, and his collaborators dealt with changes of the nucleic-acid structure, synthesized in bacteria after exposure, and, in another paper, with the favorable effects of high-polymerized desoxyribonucleic acid on the metabolic activity of the liver and intestines in rats exposed to a lethal dose; Lazurkin, USSR, studied the kinetics of processes leading to formation of free radicals in albumins during exposure; Cherkasova, USSR, dealt with the post-irradiation metabolism of albumins in the central nervous system; Benes and Soska, CSSR, reported on the effects of some pyrimidine precursors of desoxyribonucleic acids on the resumption of nucleic-acid synthesis after it had been stopped by ionizing radiation; Karpfel, CSSR, reported on increased cell division rate and formation of abnormal chromosomes in irradiated marrow of animals to which intact desoxyribonucleic acid was previously administered; Petrova, Czechoslovakia, dealt with the direct and indirect effects of radiation on Zygnema algae; Skalka, Czechoslovakia, and his collaborators studied radiation effects on the bond between desoxyribonucleic acid and albumin; Hradecna, Doctor, Czechoslovakia, dealt with radiation effects on some functions of lambda-phage; Drobnik, Czechoslovakia, reported on effects of internally administered phosphorus on diploid yeast cells.
