Atrial natriuretic peptide and aldosterone secretions, and atrial natriuretic peptide-binding sites in kidneys and adrenal glands of pregnant and fetal rats in late gestation in response to a high-salt diet

In pregnant and fetal rats, a high-salt diet decreases aldosterone secretion but does not alter ANP secretion or receptor binding, suggesting ANP is not involved in regulating water and electrolyte balance during salt loading in this model.
