Abstract
Summary
The concentrations of catechol amines with fluorescent absorption spectral characteristics similar to epinephrine and norepinephrine were determined in patients and hospital personnel in a psychiatric hospital. No significant differences were found in blood levels of catechol amines in these two groups. There were also no significant differences observed in the catechol amine levels among the various diagnostic categories within the patient group. L dihydroxyphenylalanine, tyramine, and 5 hydroxytryptamine do not appreciably interfere with the ethylenediamine method. 3 hydroxytyramine had a fluorescent potential equivalent to that of epinephrine and norepinephrine when these compounds were compared in the ethylenediamine method.
