The present study was performed to evaluate the effect of 3rdV injection on water intake of brain natriuretic peptide (BNP), which is structurally different from the atrial natriuretic peptide. BNP was recently isolated from porcine brain and appears to have a different precursor than the family of atrial natriuretic peptides. Central administration of BNP 3rdV decreased water intake. At a dose of 2.0 nmol/rat, BNP partially inhibited dehydration-induced water intake and completely blocked the stimulatory effect of 478 pmol/rat angiotensin II in rats.

D000804 Angiotensin II An octapeptide that is a potent but labile vasoconstrictor. It is produced from angiotensin I after the removal of two amino acids at the C-terminal by ANGIOTENSIN CONVERTING ENZYME. The amino acid in position 5 varies in different species. To block VASOCONSTRICTION and HYPERTENSION effect of angiotensin II, patients are often treated with ACE INHIBITORS or with ANGIOTENSIN II TYPE 1 RECEPTOR BLOCKERS.

D020097 Natriuretic Peptide, Brain A PEPTIDE that is secreted by the BRAIN and the HEART ATRIA, stored mainly in cardiac ventricular MYOCARDIUM. It can cause NATRIURESIS; DIURESIS; VASODILATION; and inhibits secretion of RENIN and ALDOSTERONE. It improves heart function. It contains 32 AMINO ACIDS.
