Dopamine and Noradrenaline Levels in Peripheral Tissues of Several Mammalian Species

Abstract

Tissue levels of dopamine and noradrenaline [norepinephrine] were compared in atrium, spleen, mesenteric artery, vas deferens and renal cortex of sexually mature rats, guinea-pigs, ferrets, rabbits and cats. Dopaminergic autonomic axons are apparently present in the cat renal cortex, as was previously reported for the dog. Such nerves are probably sparse or absent in the kidneys of the other species examined.
