...Gerald P. MCCANN; Helen CAHILL; Stephen KNIPE; Douglas F. MUIR; Paul D. MACINTYRE; W. Stewart HILLS 5-Hydroxytryptamine (5-HT; serotonin) has been implicated in the perception of exercise-induced fatigue. Sumatriptan is a selective 5-HT 1B/D receptor agonist which does not cross the blood–brain...

...D. BUNTON; A. MACDONALD; T. BROWN; A. TRACEY; J. C. MCGRATH; A. M. SHAW We compared 5-hydroxytryptamine (5-HT)- and U46619-mediated contractions in bovine pulmonary conventional arteries (CA) and supernumerary arteries (SA). The effects of the NO synthase inhibitor N G -nitro- l -arginine methyl...

...V. C. Menys; C. C. T. Smith; P. Lewins; R. D. T. Farmer; M. I. M. Noble 1. In view of the importance of 5-hydroxytryptamine in coronary thrombosis, we wanted to know whether a potentially protective decrease in platelet 5-hydroxytryptamine could be achieved by treatment with an inhibitor of 5...

...Jay D. Coffman; Richard A. Cohen 1. The involvement of plasma 5-hydroxytryptamine in normal subjects during sympathetic stimulation and in patients with Raynaud's phenomenon was studied. 2. Arterial and venous plasma levels of 5-hydroxytryptamine were measured in normal subjects in a warm room...

...A. Graham; E. W. F. W. Alton; D. M. Geddes 1. 5-Hydroxytryptamine has been suggested as a candidate for an endogenous inhibitor of airway sodium transport. Amiloride, an inhibitor of epithelial sodium channels, has therapeutic potential in disorders of airway ion transport such as cystic fibrosis...

... levels and low platelet 5-hydroxytryptamine (serotonin) levels during basal periods. After a glucose load, late peaks of dopamine and free 5-hydroxytryptamine, which coincided with the symptoms but not with the nadir of plasma glucose, were observed. Type II showed a low basal plasma noradrenaline...

In vitro , muscarinic activation by pilocarpine increased the pineal metabolic production of hydroxyindole derivatives up to 5-hydroxytryptamine and produced a less marked stimulation of melatonin biosynthesis. 3. Electrical field stimulation of pineal gland slices caused similar...

At moderate and heavy levels of exercise, the results are compatible with a role for 5-hydroxytryptamine in pressure regulation...
