Dopamine surges in hyperadrenergic essential hypertension.
From a total of 61 referred hypertensive patients, 21 were clinically suspected of pheochromocytoma but in none was this diagnosis confirmed. Instead we found nine of the 21 patients had surges of conjugated dopamine during hyperadrenergic periods unaccounted for by rise in norepinephrine (NE) or epinephrine (E). Overall, essential hypertensive (EH) patients had in plasma (ng/ml) higher conjuga...
متن کاملThe meaning of dopamine p - hydroxylase in essential hypertension
1. Resting plasma dopamine B-hydroxylase (DBH) activity and haemodynamic parameters were studied in untreated borderline (twenty-nine) and permanent (twenty-seven) essential hypertensive patients. DBH was also measured in sixty-three apparently healthy subjects. 2. Mean DBH values were not significantly different between the groups. 3. Cardiac output, cardiopulmonary blood volume and the cardio...

متن کاملDopamine D1 receptor gene polymorphism is associated with essential hypertension.
Dopamine has been shown to influence renal sodium excretion through a direct interaction with the dopamine receptor (DR). The dopamine D1 receptor (DRD1) has been localized to the proximal tubules and is known to increase sodium excretion by inhibiting Na-H exchanger and Na,K-ATPase activity. Defective renal dopamine production and/or DR function have been reported in essential hypertension (EH...
متن کاملCentral Dopamine and Serotonin Turnover in Schizophrenia
Comparison of C.S. F. H. V. A and 5-HIAA levels of 20 Schizophrenics and 9 non-schizophrenic controls revealed no statistically significant difference between HVA levels but the 5-HIAA levels were significantly less in Schizophrenics (p < 0.05) than in controls. The significance of these findings is discussed.
