more recently we have demonstrated that alpha-adrenergic receptors , assessed by ligand binding with 3h-prazosin , increased nearly twofold in ischemic myocardium by 30 minutes ( bmax = 14 + 2 to 27 + 3 fmol/mg prot ) and remain elevated during early reperfusion ( 12 + 1 to 18 + 1 ) before returning to control values by 15 minutes after reperfusion .
