Preparations effective in a wide range of radiation doses of various intensity were synthesized. Their activity are due to combination of antiradiation and many other pharmacological properties. During acute radiation these preparations protect stem cells pul of critical tissues but under prolonged radiation they normalize the hematological, immune and lipid peroxide oxidation systems. There is no strong correlation between radioprotection and increasing of functional reserve of organism.

In this work the nucleotide sequence of rimantadine- and deytiforine-resistant influenza A strain Leningrad/156/83 (H3N2) was compared with that of A/Victoria/35/72. The influence of aminoacid substitutions in the M2 protein on its secondary structure in the membrane and its role in resistance development was shown.
