Plasma dopamine-beta-hydroxylase activity in oral contraceptive hypertension.
A prospective study was undertaken to evaluate the relative contribution of changes in sympathetic nervous system activity, as reflected by changes in dopamine-beta-hydroxylase (DBH) activity, to the pathogenesis of oral contraceptive-induced hypertension. Precontraceptive and serial post contraceptive determinations of blood pressure, plasma renin activity (PRA), DBH activity, and changes in b...
متن کاملSerum dopamine-beta-hydroxylase activity.
Dopamine-yS-liydroxylase, the enzyme which converts dopamine to norepinephrine, is released into the perfusate upon stimulation of the isolated perfused adrenal gland and after stimulation of the nerves to the isolated perfused spleen. This study was undertaken to determine whether dopamine-/?hydroxylase activity could be detected circulating in blood. By using a sensitive new enzymatic assay, ...
متن کاملEffect of beta-adrenergic blockade on plasma dopamine-beta-hydroxylase activity and triiodothyronine in hyperthyroidism.
The effect of propranolol on plasma dopamine-beta-hydroxylase activity and triiodothyronine was investigated in twelve subjects with Graves' disease. Plasma DBH activity, serum triiodothyronine and thyroxine were determined beforehand and electrocardiograms were recorded on the same days as the blood samples were taken. Propranolol administration was associated with clinical amelioration in blo...
متن کاملPlasma norepinephrine concentration and plasma dopamine-beta-hydroxylase activity in patients with congestive heart failure.
The relationship between plasma norepinephrine (NE), epinephrine (E) and dopamine-beta-hydroxylase activity (DBH) was studied in 90 cardiac patients (New York Heart Association [NYHA] classes I-IV), 85 healthy control subjects and 18 competitive skiers. The cardiac patients in NYHA classes III and IV had significantly higher NE (p less than 0.001) and lower DBH (p less than 0.001) levels than t...
متن کاملLack of correlation between serum dopamine-beta-hydroxylase activity and blood pressure in middle-aged men.
The activity of serum dopamine-beta-hydroxylase (DBH) was measured in 1194 asymptomatic middle-aged men with diastolic blood pressure ranging from 75 to 125 mm Hg during the baseline examination of a multifactorial intervention program for primary prevention of coronary heart disease. No correlation was present between serum DBH activity and systolic (r = -0.01, NS) or diastolic (r = +0.02, NS)...
