title: [The role of beta-adrenoreceptors in the mechanism of the hemodynamic action and radiation-protective activity of the copolymer of 2-methyl-5-vinylpyridine with 2-methyl-5-vinylpyridinium-N-oxide].
abstract: In experiment on anesthetized dogs and cats in was shown that the new water-soluble copolymer initiated depressive reaction characteristic for beta-adrenomimetics. This effect was levelled with the help of non-selective adrenoblockator--propranololum. In experiment on dogs the preliminary treatment with propranololum decreased the therapeutic antiradiation efficiency of the copolymer from 68.4 to 8.3%.
