Catecholamines and their major metabolites in plasma and cerebrospinal fluid of man. 1981

N D Vlachakis, and C Lampano, and N Alexander, and R F Maronde

In 36 patients undergoing elective surgery under spinal anesthesia, plasma and cerebrospinal fluid (CSF) concentrations of catecholamines and their major metabolic products were determined. The development of specific and sensitive radioenzymatic assays make these determinations possible. The levels of norepinephrine, epinephrine, and the O-methylated metabolite, normetanephrine, were greater in the plasma then the CSF, although the difference was significant for norepinephrine and epinephrine only (P less than 0.01 for both) On the other hand the levels of both deaminated metabolites dihydroxyphenylglycol (DOPEG) and dihydroxymandelic acid (DOMA) were greater in the CSF the in plasma, but the difference was significant for DOPEG only (P less than 0.01). Although there was a positive and significant correlation between the levels in plasma and CSF of all these compounds, their concentrations in CSF may reflect metabolism of catecholamines in the central nervous system.

D008875	Middle Aged	An adult aged 45 - 64 years.	Middle Age
D009638	Norepinephrine	Precursor of epinephrine that is secreted by the ADRENAL MEDULLA and is a widespread central and autonomic neurotransmitter. Norepinephrine is the principal transmitter of most postganglionic sympathetic fibers, and of the diffuse projection system in the brain that arises from the LOCUS CERULEUS. It is also found in plants and is used pharmacologically as a sympathomimetic.

D009647	Normetanephrine	A methylated metabolite of norepinephrine that is excreted in the urine and found in certain tissues. It is a marker for tumors.	3-Methoxynoradrenaline,Normetadrenaline,3 Methoxynoradrenaline
D001921	Brain	The part of CENTRAL NERVOUS SYSTEM that is contained within the skull (CRANIUM). Arising from the NEURAL TUBE, the embryonic brain is comprised of three major parts including PROSENCEPHALON (the forebrain); MESENCEPHALON (the midbrain); and RHOMBENCEPHALON (the hindbrain). The developed brain consists of CEREBRUM; CEREBELLUM; and other structures in the BRAIN STEM.	Encephalon

D004837	Epinephrine	The active sympathomimetic hormone from the ADRENAL MEDULLA. It stimulates both the alpha- and beta- adrenergic systems, causes systemic VASOCONSTRICTION and gastrointestinal relaxation, stimulates the HEART, and dilates BRONCHI and cerebral vessels. It is used in ASTHMA and CARDIAC FAILURE and to delay absorption of local ANESTHETICS.
