The effect of aqueous extract of pomegranate seed on rat uterine smooth muscle contractility
Introduction: Considering the importance of uterine contractions in uterus retraction and reducing post-partum hemorrhage and the current findings on the effect of the alcoholic extract of pomegranate seed on the uterine contractility, only few studies were made on this issue. In the present study the cumulative effect of the aqueous extract of pomegranate seed on the uterine smooth muscle c...

متن کاملPeroxynitrite reversibly inhibits Ca(2+)-activated K(+) channels in rat cerebral artery smooth muscle cells.
Peroxynitrite (ONOO(-)) is a contractile agonist of rat middle cerebral arteries. To determine the mechanism responsible for this component of ONOO(-) bioactivity, the present study examined the effect of ONOO(-) on ionic current and channel activity in rat cerebral arteries. Whole cell recordings of voltage-clamped cells were made under conditions designed to optimize K(+) current. The effects...
متن کاملCa binding of intestinal smooth muscle myosin B.
By means of both centrifugation and filtration techniques, the Ca binding activity of intestinal myosin B was studied. The binding capacity of myosin B was Ca dependent and was approximately linear when the concentration of Ca in the medium ranged from 10(-4) to 10(-7) M. The Ca sensitivity of ATPase activity in the same range of Ca concentration exhibited a sigmoid curve. The Scatchard plot of...
