چکیده
A sensitive and specific double-isotope dilution method for assaying norepinephrine and epinephrine separately is described. The method is based on enzymatic conversion of these two catecholamines to their respective metanephrines and was applied successfully to measurement of resting plasma concentrations of norepinephrine and epinephrine in normal subjects with the finding that norepinephrine (0.20 ± 0.08 fig/liter) normally constitutes approximately 80% of the plasma catecholamine content and epinephrine (0.05 ± 0.03 fig/liter) 20%.

متن کاملSerial determination of plasma catecholamines in myocardial infarction.
SUMMARY By the use of a precise and sensitive double-isotope derivative technic, plasma cate-cholamine concentration was measured at 2-hour intervals in 10 patients during the first 48 hours of myocardial infarction. Plasma catecholamine concentration was elevated in most patients, but to an extremely variable degree. In each patient, however, the values were rather stable during the study peri...
متن کاملRadioenzymatic determination of epinephrine, norepinephrine and dopamine in 0.1 ml plasma samples: plasma catecholamine response to submaximal and near maximal exercise.
A sensitive enzymatic isotope derivative method for simultaneous determination of epinephrine, norepinephrine, and dopamine in 0.1 ml plasma samples is described. The assay consists basically of 1. conversion of epinephrine, norepinephrine, and dopamine into their respective methyl-derivates in the presence of catechol-O-methyltransferase and S-adenosylmethionine-[3H]methyl, 2. extraction of th...
متن کاملThe effect of short-term caffeine-beet juice supplementation on catecholamine changes, lactate and Rating of Perceived Exertion before intense anaerobic activity in runners: A double-blind randomized clinical trial study
Background and Purpose: Intense anaerobic activity is used to improve anaerobic power and lactate threshold .The aim of this study was to investigate the changes in catecholamines, rating of perceived exertion and lactate supplementation with short-term caffeine and beet juice before intense anaerobic activity in runners. Methodology: In this study, 30 high performance runners (age: 27.5±3.8 y...
متن کاملDevelopment of a Simple and Sensitive Terbium Sensitized Fluorescence Method for Determination of Epinephrine and Norepinephrine in Serum
A simple, rapid, selective and highly sensitive fluorimetric method for determination of two catecholamines, i.e. norepinephrine (NE) and epinephrine (EP), in serum samples was developed. The method is based on the fluorescence sensitization of terbium (Tb3+) by complexation with both catecholamines in the presence of lanthanum (La3+), as a co-cation, and in a Na...
