the increases in and beta-adrenoceptor densities in essential hypertension were accompanied by enhanced responsiveness alpha- of platelets to 10 microm adrenaline to adrenergic stimulation : the aggregatory response via alpha 2-adrenoceptor stimulation ) was increased , and in lymphocytes isoprenaline ( 0.01 - 100 microm ) produced ( via adrenoceptor stimulation ) greater increases in cyclic amp at each concentration than in control .
