Dopaminergic control of prolactin and blood pressure.

Dopaminergic control of prolactin and blood pressure.

Dopaminergic control of prolactin and blood pressure: altered control in essential hypertension.

This study examines the influence of dopamine on plasma catecholamine, prolactin (PRL), and mean arterial pressure (MAP) responses to upright posture and isometric handgrip exercise and the recumbent circadian PRL and MAP patterns in essential hypertension. Nine men with sustained essential hypertension and nine ageand weight-matched normotensive controls were studied after they had reached met...

The intrarenal renin-angiotensin and dopaminergic systems: control of renal sodium excretion and blood pressure.

T he renin–angiotensin system (RAS) is a coordinated hormonal cascade critical to the control of renal sodium (Na +) excretion and blood pressure (BP). 1 Angiotensin II (Ang II), the principal RAS effector peptide, binds to 2 distinct receptors, the Ang type-1 receptor (AT 1 R) and the Ang type-2 receptor (AT 2 R) with high affinity. The vast majority of actions of Ang II are transmitted via AT...

Dopaminergic control of sympathetic tone and blood pressure: evidence in primary hypertension.

Bromocriptine (Br) was used to test the hypothesis that central dopaminergic mechanisms modulate sympathetic nerve tone, and that when dopaminergic control is deficient there may result enhanced noradrenergic activity and elevated blood pressure (BP) in some patients with primary hypertension. Seven hypertensive patients (age 29 ± 3 years) were studied after a single oral dose of Br (2.5-5.0 mg...
