[Dopamine hydro-natriuresis. - II) Interactions of dopamine and expansion of extracellular liquid volume].


We have observed that in the presence of salt retention (DOCA pretreatment) dopamine (DA) promoted a hydro-natriuretic effect; in contrast in salt depletion (natriuretic pretreatment) the changes in sodium tubular reabsorption and in urinary flow were non significant. The present study was designed to identify the possible mechanisms underlying the hydro… (More)
