Why the study?
Does simultaneous potassium and saline loading affect plasma aldosterone levels compared to saline or potassium alone in normal salt-depleted subjects?
Population

No immediate clinical implications for aldosterone assessment; extends physiological models of additive renin-potassium effects in salt depletion.
Does simultaneous potassium and saline loading affect plasma aldosterone levels compared to saline or potassium alone in normal salt-depleted subjects?
In the salt-depleted state, the renin-angiotensin system and potassium are equally important and have an additive effect in the acute regulation of plasma aldosterone levels.
Dluhy et al. (1977) studied this question.
