Endothelium-Independent Vasodilatory Effect of Sailuotong (SLT) on Rat Isolated Tail Artery

<div>Effects of potassium channel blockers on SLT extract-induced relaxation on phenylephrine (1 <i>μ</i>M)-preconstricted rat isolated tail artery. Tail arteries were preincubated with either vehicle control (○), tetrethyl-ammonium (TEA, a nonselective potassium channel blocker) (1 mM) (●), glibenclaminde (Glib, an ATP-sensitive potassium channel blocker) (3 <i>μ</i>M) (■), or clotrimazole (KCa, a calcium-activated potassium channel blocker) (5 <i>μ</i>M) (▲) for 30 minutes before construction of the concentration-response curve. Values are expressed as mean ± SEM (<i>n</i> = 5-6).</div>
