[Serotonin in arterial hypertension]

Serotonine was determined in 67 patients, 39 with arterial hypertension and 28--with normal arterial pressure. The patients are grouped into three: first group--males and females with confirmed atherosclerosis without and with systolic hypertension; the second group covers males with atherosclerosis without and with systolic hypertension and the third group --males and females with hypertonic diseases, II stage, the basic disease being complicated by atherosclerosis. The highest serotonine values were found in the patient groups without and with systolic hypertension, hypertonic disease with systolic-diastolic hypertension in males with diagnosed atherosclerosis. Serotonine impressed to be relatively lower in the females with hypertonic disease and atherosclerosis. Some humoral factors in females are presumed to be probable causes for those differences but further studies are still necessary.
