| O Iimura, K Shimamoto, N Ur. Dopaminergic activity and water-sodium handling in the kidneys of essential hypertensive subjects: is renal dopaminergic activity suppressed at the prehypertensive stage? Journal of cardiovascular pharmacology. vol 16 Suppl 7. 1991-05-23. PMID:1708026. |
these findings suggest that renal dopaminergic activity is already suppressed at the prehypertensive stage, and a reduction in the conversion from l-dopa to dopamine in the proximal tubules may contribute to the attenuation of renal dopaminergic activity in fh(+) subjects. |

both a dopaminergic antagonist, haloperidol (10(-5) and 10(-4)m), and an alpha-adrenoceptor antagonist, phentolamine (10(-7) to 10(-5)m), attenuated the contraction to 10(-3)m dopamine. |

however, the contraction could only be abolished by phentolamine at 10(-4) m. thus, in canine tracheal smooth muscle, the contractile response to dopamine is predominantly through the activity of alpha-adrenoceptors and the role of dopaminergic receptors is vague. |
