A new strategy for measurement of brain catecholamines was tested in an animal model. [3H]Norepinephrine was infused intravenously in rabbits to label the peripheral norepinephrine pools. The specific activity of urinary 3-methoxy-4-hydroxymandelic acid was consistently higher than that for 3-methoxy-4-hydroxyphenylglycol (MHPG). Central sympathectomy with 6-hydroxydopamine abolished this difference. Using the formula we propose, it is estimated that 30–50% of urinary MHPG originates from the central nervous system.

AbstractThe adsorption of 1-hydroxyethylidene-1,1 -diphosphonic acid (HEDP) on an iron electrode in neutral aqueous solution has been examined by the radiotracer method. The role of calcium and zinc cations in the adsorption mechanism has also been studied in order to understand the synergistic effect when HEDP is applied together with these cations
