Participation of 5-HT1-Like Receptors and 5-HT2 Receptors in Serotonin-Induced Contraction of Human Isolated Coronary Arteries 5-HT1-Like Receptors Resemble Cloned 5-HT1Dp Receptors
Background Serotonin may contract human large coronary arteries through two 5-hydroxtryptamine (5-HT) receptors, 5-HT1-like and 5 -HT2. These 5-HT1-like receptors resemble both cloned 5-HT1D receptor subtypes, 5-HT'1D, and 5 -HT1Ds. Although these subtypes have similar pharmacology, 5-HT1Dg receptors appear to have lower affinity for ketanserin than 5-HT1Di receptors. We assessed the relative p...
متن کاملMuscarinic receptor subtype in isolated dog and monkey facial vein.
Using the cannula inserting method, we investigated vascular responses to ACh and McN-A-343 (a M1-agonist) in isolated and perfused canine and simian facial veins in non-preconstricted conditions. ACh usually induced only a vasoconstriction, but McN-A-343 did not induce any significant vasoconstriction. It is concluded that canine and simian facial veins contain very few receptors of the muscar...
متن کامل5-Hydroxytryptamine(1F) receptors do not participate in vasoconstriction: lack of vasoconstriction to LY344864, a selective serotonin(1F) receptor agonist in rabbit saphenous vein.
Recently, several novel approaches to the treatment of migraine have been advanced, including selective 5-hydroxytryptamine (or serotonin) 1B/1D (5-HT(1B/1D)) receptor agonists such as sumatriptan and 5-HT(1F) receptor agonists such as LY344864. Many 5-HT(1B/1D) receptor agonists have been identified based on their ability to produce cerebral vascular contraction, whereas LY344864 was identifie...
متن کاملA comparison of the effects of 5- and 6-hydroxydopamine on the isolated canine saphenous vein.
We studied and compared the effects of 5- and 6-hydroxydopamine (5- or 6-OHDA) on venous tone and on adrenergic and nonadrenergic responses of the isolated canine saphenous vein. In the tissue bath, both 5- and 6-OHDA caused increases in tone and abolished adrenergic responses to transmural nerve stimulation. Effects of 6-OHDA were blocked by desmethylimipramine. 6-OHDA reduced norepinephrine l...
متن کاملSelective retention of the great saphenous vein to prevent saphenous nerve injury during varicose vein surgery.
OBJECTIVE To explore the selective retention of the great saphenous vein trunk below the knee to prevent saphenous nerve injury during varicose vein surgery. PATIENTS AND METHODS This research was a single-center prospective randomized trial. From January 2009 to January 2012, 280 patients of varicose veins in the great saphenous vein were treated and divided into two groups of 140 cases each...
