[Serotonin, histamine and catecholamine levels in patients with the hyperprolactinemia syndrome].

A total of 76 patients aged 18-39 with hyperprolactinemia were studied for the blood levels of serotonin and histamine and for the urinary ones of epinephrine, norepinephrine, dopa and dopamine. Blood levels of serotonin and histamine were recorded increased whereas the urinary levels of catecholamines were decreased. No correlation was shown between the intensity in the production of lactogenic hormone and those abnormalities found in the levels of the above mentioned amino groups.
