to define the functional role of postsynaptic alpha-adrenoceptors in urethral smooth muscle , we examined the effects of various alpha-adrenergic agonists and antagonists on the contractile properties of the isolated urethra of male and female rabbits and quantified the population of alpha 1-and alpha 2-adrenoceptors , using radioligand receptor binding techniques .
