Relaxation and changes in the transmembrane potential of vascular smooth muscle induced by ORM-3819, a novel inodilating compound, were investigated in isolated porcine coronary arteries. Isometric tone was studied on arterial rings precontracted by

Radial artery frequently develops spasm and requires vasodilator therapy during coronary artery bypass graft surgery (CABG). Levosimendan was recently shown to oppose 5-hydroxytryptamine-induced contraction of radial artery (RA) grafts. The aim of th

Objective: Radial arteries are increasingly used as grafts in coronary artery bypass surgery. The surgical preparation and intraoperative management of this conduit artery may affect its early and long-term patencies. We investigated the effects of t

Aims: Functional roles of calcium-activated potassium channels on the mechanical activity of epicardial coronary arteries obtained from a canine model of diabetes were investigated. Methods: Coronary arteries were isolated from healthy, alloxan-diabe

The present study was designed to investigate the functional K+ channels involved in contractions induced by electrical field stimulation in isolated rat penile arteries. Blockers of Ca2+-activated K+ channels (KCa), tetraethylammonium, and of large-

Levosimendan, a new type of inodilator drugs, is known to activate membrane adenosine 3′,5′-triphosphate-sensitive potassium (KATP) channels in some vascular smooth muscles and causes vasorelaxation. The involvement of potassium channels in the m

The purpose of this study was to investigate the vasoactivity of two inhibitors of potassium ion (K(+) ) channels, a potential antiarrhythmic compound, AVE 0118, and 4-aminopyridine (4-AP). Basal and stimulated tones of rat small mesenteric arteries

In the present study the vasorelaxing capacity of cromakalim, an ATP-sensitive potassium-channel (KATP channel) activator, and that of levosimendan, a new positive inotropic and vasodilating drug with calcium sensitizing and potassium-channel-activat

The very fact that a simple molecule such as NO, can play a key bioregulatory function in a number of physiological responses is simply astonishing in view of the fact that most biologically active molecules are rather complex. In order to understand

Vasorelaxation caused by some antifibrinogen RGD (Arg-Gly-Asp-containing) peptides and their basic mechanism of action was studied on rabbit isolated thoracic aortic rings preconstricted with 0.25 μM phenylephrine. GRGDS (Gly-Arg-Gly-Asp-Ser-OH) and
