Biosynthesis of Epinephrine and Norepinephrine
as the sympathetic neurohormone has evolved fronm much impressive circumistantial evidence; however, it has not been demonstrated that the biosynthesis of norepinephrine takes place in the sympathetic nerves and ganglia. This paper shows, through the use of labeled precursors, that the sympathetic nerves and ganglia synthesize norepinephrine in a systematic sequence from tyrosine and that this ...
متن کاملDifferent adrenal sympathetic preganglionic neurons regulate epinephrine and norepinephrine secretion.
Brain stimulation or activation of certain reflexes can result in differential activation of the two populations of adrenal medullary chromaffin cells: those secreting either epinephrine or norepinephrine, suggesting that they are controlled by different central sympathetic networks. In urethan-chloralose-anesthetized rats, we found that antidromically identified adrenal sympathetic preganglion...

متن کاملNeuronal reuptake of norepinephrine and production of dihydroxyphenylglycol by cardiac sympathetic nerves in the anesthetized dog.
BACKGROUND Reuptake of norepinephrine by cardiac sympathetic nerves before and during two levels of electrical stimulation of the left ansa subclavia was estimated in anesthetized dogs from the cardiac production of dihydroxyphenylglycol (DHPG), the intraneuronal metabolite of norepinephrine. METHODS AND RESULTS The method depended on the effects of neuronal uptake blockade with desipramine o...
متن کاملCO2 asphyxia increases plasma norepinephrine in rats via sympathetic nerves.
The objective of this study was to determine whether the plasma norepinephrine (NE) increase in rats exposed to CO2 asphyxia was due to adrenal gland release or sympathetic nerve ending (SNS) release. Plasma NE was measured by high-performance liquid chromatography in hypertensive and normotensive rats using the following protocol: control session, CO2 exposure, N2 exposure, reserpine + CO2, an...
