to study beta-adrenoceptor antagonist-induced changes in human vascular beta-adrenoceptors , we determined the effects of chronic treatment with different beta-adrenoceptor antagonists without intrinsic sympathomimetic activity ( isa ) on beta 2-adrenoceptor density ( assessed by ( - ) - [ 125i ] -iodopindolol binding ) in human saphenous vein membranes obtained from patients undergoing coronary artery bypass grafting .
