Sulfoconjugation of catecholamines, nutrition, and hypertension.
Sulfoconjugation is an important metabolic pathway determining the fate and potential cardiovascular action of ingested phenolic substances. Among the three catecholamines, dopamine (DA) is to the highest degree sulfoconjugated and has the highest affinity toward the phenolsulfotransferase (PST). The concentration of some sulfated catecholamines, particularly of DA sulfate, increases following ...
متن کاملCatecholamines and hypertension.
Ever since the demonstration that the active principle in the adrenal medulla can raise blood pressure (Oliver & Schafer, 1895), catecholamines have been implicated in the hypertensive diseases. The identity of noradrenaline as the neurotransmitter of sympathetic nerves (von Euler, 1946) and the demonstration that an injection of this catecholamine can produce cardiovascular changes similar to ...
متن کاملPlasma Catecholamines and Essential Hypertension
Of 78 comparative studies of plasma catecholamines in patients with essential hypertension and in normotensive controls, most reported higher catecholamine levels in the hypertensives, although only about 40% of the studies were positive (reporting statistically significant hypertensivenormotensive differences). Although there was dramatic variability in catecholamine values within and across s...
متن کاملFree and conjugated catecholamines in human hypertension.
1. Noradrenaline and adrenaline in the adrenal vein of essential hypertensive patients are almost exclusively (99%) unconjugated or free. However only 17% of dopamine is free, the rest is conjugated. The further the site of sampling from the adrenal vein the closer come the free catecholamines to their normal peripheral venous proportion (noradrenaline + adrenaline 20%, dopamine less than 1% of...
متن کامل[Arterial hypertension and increased urinary catecholamines].
We report the history of a 39-year-old-man who suffered from refractory arterial hypertension and who was referred to us for the diagnosis of phaeochromocytoma due to increased urinary free catecholamines. The work-up revealed the diagnosis of cocaine-induced arterial hypertension. The pathogenesis of cocaine-induced arterial hypertension as well as the differential diagnosis of increased urina...
