Changes in .ALPHA.-adrenergic receptors in rat brain in vitro by preincubation with .ALPHA.-adrenergic ligands.

Interesting findings on a-adrenergic receptors in brain (1-4) and many peripheral organs (5-9) have been obtained using radiolabeled specific ligands with high specific activity for these receptors.It has been reported that (3H)WB4101, (3H)2-((2',6'-dimethoxy)phenoxy
