Serotonin appears to play an important part in the pathogenesis of essential hypertension. Various studies have shown, that the metabolism of serotonin may be disturbed in some pathological conditions for example in hypertension. It concerns also the changed mechanisms of uptake and release of serotonin. The certain blood vessels may become more hypersensitive to the vasoconstrictor effects of serotonin in patients with hypertension than in normal subjects. During chronic treatment with ketanserin, S2-serotonergic antagonist, blood pressure is reduced in spontaneously hypertensive rats and in humans. This fact can also indicate indirectly, that that serotonin plays a part in the pathogenesis of essential hypertension. The aim of the study was to determine the concentration of free serotonin (S) in the blood of 15 patients with sustained essential hypertension in the mean age 32.8 +/- 1.8, of 23 patients with borderline essential hypertension in the mean age 29.0 +/- 3.0 and of 10 normal subjects in the mean age 31.1 +/- 1.7 years. Plasma free serotonin was determined by fluorometric method. All patients and controls were investigated at the hospital. They were on normosodium diet, without drugs for last two weeks. The fasting blood samples were collected in the supine position. Free serotonin blood concentration was significantly higher in hypertensive group than in normal subjects. The important difference of serotonin blood concentration between two groups of hypertensive patients was noticed. It was significantly higher in group of patients with sustained hypertension, than in group with borderline hypertension (p less than 0.05). Our results are similar to the observations of other authors.(ABSTRACT TRUNCATED AT 250 WORDS)
