The occurrence of dopamine and related metabolites in the coronary and some other arteries.
1. Bovine coronary and other arteries contain more dopamine (DA) [1400-520 ng g-1] than noradrenaline (NA) [120-500 ng g-1] with high DA/NA ratios (1.8-4.3). Arteries from other species, (pigs, rats, mice or guinea-pigs), contain far less DA (20-60 ng g-1) and have lower DA/NA ratios (0.01-0.06). 2. Bovine arteries also have 3,4-dihydroxyphenylacetic acid (80-290 ng g-1) but not homovanillic acid (less than 20 ng g-1). 3. It remains to be elucidated whether, in the bovine arterial wall, DA is a transmitter or it is associated with chromaffin-like cells.
