[Biochemical characterization of central alpha-adrenergic receptors].

Successively are learned in this paper general characteristics of cental alpha-adrenergic receptors and individualization of alpha 1- and alpha 2-adrenergic sub-groups, biochemical factors which are able to affect fixation of their respective ligands and finally physiological and pathological variations of alpha 1- and alpha 2-adrenergic receptors, which will allow to discuss their participation in different regulations and disorders.
