Characterization of the beta-adrenergic receptors in the lower urinary tract of the cat.
The corpus-fundus and the outlet region of the urinary bladder of the cat was studied in vitro to characterize the beta-adrenergic receptors. In the corpus-fundus only beta1-receptors were found in contrast to the outlet region where the beta-receptors had both beta1-and beta2-characteristics.
