the contractile response of the rat isolated urinary bladder to kinins is meated by receptors of the b1 and of the b2 types , as this preparation responds to des-arg9-bradykinin ( des-arg9-bk ) , a fairly selective stimulant of receptor b1 and to [ tyr ( me ) 8 ] -bk , a potent agonist on receptor b2 .
