title: [Mechanism of the radioprotective effect of catecholamine receptor agonists. Inclusion in the radioprotective effect of different subtypes of beta-adrenoreceptors].
abstract: Isoproterenol of ED50 = 0.16 mumol/kg is highly effective in protecting mice against ionizing radiation and has the high therapeutical index. There are three new indications that isoproterenol exerts its radioprotective action via beta-adrenoceptors. They are: the effect of isoproterenol is prevented by three additional beta-adrenoceptor antagonists, the isoproterenol effect is reproduced by the seven studied beta-adrenoceptor agonists of different chemical structure, and with chemical analogs which fail to stimulate beta-adrenoceptors the radioprotective effect is absent. Both beta 1 and beta 2 adrenoceptor agonists are protective agents. Mechanisms of the radioprotective action are discussed.
