to assess the possible relation between catecholamine responses and adrenoceptor affinity and density , we compared the effect of noradrenaline , isoprenaline and ouabain on the right ventricular muscle strips from normal and cardiomyopathic hamsters with alpha 1- and beta-adrenoceptor characteristics assessed by radioligand binding methods .
