Norepinephrine Infusion
To study the possible role of catecholamines in platelet activation, platelet aggregation stimulated by AI?P, collagen, arachidonic acid and l-epinephrine, thromboxane B2 (TXB2) formation and plasma levels of catecholamines and renin were studied in healthy men both before and after 6 days of propranolol treatment (40 mg three times daily) under control conditions and during sympathoadrenergic ...
متن کاملHuman norepinephrine metabolism. Its evaluation bydministration of tritiated norepinephrine.
It has become increasingly apparent that evaluation of human norepinephrine metabolism simply by assay of catecholamines in urine is inadequate for differentiation of many physiological or pathological states. In an attempt to examine norepinepherine metabolism in the human subject, tritium-labeled d,l-norepinephrine was administered to 11 normal adults and the definitive turnover rates and rel...
متن کاملCardiac Norepinephrine Depletion
Since there is an overall augmentation of sympathetic nervous activity in patients with congestive heart failure while adrenal medullary function is normal and neurotransmitter stores are diminished in the heart, investigation was directed to the functional status of adrenergic receptors and available norepinephrine stores in the peripheral vascular beds. Blood flow, determined plethysmographic...
متن کاملNorepinephrine Metabolism in Humans
The present study was undertaken to quantify more precisely and to begin to address the problem of heterogeneity of the kinetics of distribution and metabolism of norepinephrine (NE) in humans, by using compartmental analysis. Steadystate NE specific activity in arterialized plasma during I3HINE infusion and postinfusion plasma disappearance of [3HINE were measured in eight healthy subjects in ...
متن کاملNorepinephrine and Neural Interrupts
Experimental data indicate that norepinephrine is critically involved in aspects of vigilance and attention. Previously, we considered the function of this neuromodulatory system on a time scale of minutes and longer, and suggested that it signals global uncertainty arising from gross changes in environmental contingencies. However, norepinephrine is also known to be activated phasically by fam...
