The effect of dopamine on renal cortical blood flow in baboons with experimentally induced obstructive jaundice. 1978

L Bomzon, and P B Wilton, and M C Kew

The effect of dopamine hydrochloride on renal blood flow in bile duct ligated baboons was assessed using the 133Xe washout technique. Intrarenal infusions of dopamine in different concentrations did not significantly increase renal cortical blood flow. On the contrary, over the lower dose range, the normal dopamine-induced renal vasodilatation was abolished in the jaundiced state. An in vitro experiment that measured the perfusion pressure of an isolated rabbit kidney perfused with normal and jaundiced baboon plasma confirmed the in vivo results. These observations suggest that dopamine would not be of value in treating the renal failure that may develop in patients with obstructive jaundice.

D004298 Dopamine One of the catecholamine NEUROTRANSMITTERS in the brain. It is derived from TYROSINE and is the precursor to NOREPINEPHRINE and EPINEPHRINE. Dopamine is a major transmitter in the extrapyramidal system of the brain, and important in regulating movement. A family of receptors (RECEPTORS, DOPAMINE) mediate its action.
