Atrial natriuretic peptide(s) (ANP) (Atriopeptin) are peptide hormones that regulate vasodilation. The ANP fragment Atriopeptin III (ANP 127-150) is used to study the regulation of Na+/H+ exchange mediated in erythrocytes by cGMP/guanylate-cyclase activity.

1. In mammalian plasma, many different inhibitors of Na+/K(+)-ATPase are present, but it is not clear whether their net effect on NA+/K(+)-ATPase activity changes during the regulation of electrolyte and fluid balance. We studied Na+/K(+)-ATPase inhibition by plasma extracts in

Human atrial natriuretic peptide (ANP) fragments ANP-(127-150) or ANP-III and ANP-(127-149) or ANP-II activate Na+/H+ exchange in human erythrocytes at concentrations as low as 1 pM. Both ANP-(127-147) or ANP-I and ANP-(129-150) or des-Ser5, Ser6-ANP-III have no effect on erythrocyte

Guanylate cyclase activity in human erythrocytes is investigated by evaluating the intracellular guanosine 3',5'-cyclic monophosphate (cGMP) content in the presence of various agents that exert specific effects on soluble or particulate guanylate cyclase. The increase in the intraerythrocyte cGMP content
