title: [Mechanism of the radioprotective effect of catecholamine receptor agonists. Inclusion in the radioprotective effect of both subtypes of alpha-adrenoreceptors].
abstract: alpha-Adrenoceptor agonists of both main groups, i. e. arylalkylamines and imidazolines, have a pronounced radioprotective effect. Their chemical analogs, which fail to stimulate alpha-adrenoceptors, do not protect mice. The effect of phenylephrine, adrenaline, and noradrenaline comes into play via alpha 1-adrenoceptors and that of clonidine, via alpha 2-adrenoceptors and also via alpha 1-adrenoceptors. Adrenoceptor agonists can probably manifest their radioprotective action via both subtypes of alpha-adrenoceptors. Possible intracellular mechanisms of the radioprotective action are discussed.
