title: Neuronal accumulation and metabolism of 3H-1-norepinephrine in rat portal vein: evidence in relation to possible uneven alpha receptor distribution.
abstract: The rate of accumulation and metabolism of 3H-1-norepinephrine in the neuronal plexus of rat portal vein produces a small transmitter concentration gradient across the longitudinal smooth muscle layer which cannot account for the prejunctional supersensitivity observed and suggests localization of the alpha-adrenergic receptors adjacent to the nerve plexus.
