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...

Effects of ginger extract on smooth muscle activity of sheep reticulum and rumen

Reticulorumen hypomotility leads to the impaired physiologic functions of the digestive tract. Prokinetic action of ginger has been demonstrated in the laboratory animals and human. The aim of this study was to evaluate the effect of hydroalcoholic extract of ginger on contraction and motility of reticulum and rumen of ruminants. Collected samples of reticulum and rumen from eight sheep were in...

Effect of New Derivatives of Dihydropyridine on Rat Ileal Smooth Muscle in Vitro

In this research we evaluated the calcium channel antagonist activity of various diester analohues of nifedipine on rat ileal smooth muscle.in these analogues,the orthophenyl group at position 4 was replaced by 1 methyl 2-meythylsulfonyl or methylthio 5-imidazolyl.wistar rats(180-250g) were killed by a blow to the head.the intestine was removed above the ileucecal junction and longitudinal smoo...

Hydro-ethanolic Extract of Portulaca oleracea Affects Beta-adrenoceptors of Guinea Pig Tracheal Smooth Muscle

The stimulatory effect of the extract of Portulaca oleracea (P. olerace) on β-adrenoceptor of tracheal smooth muscle was examined. To examine β-adrenoceptor stimulatory effect, concentration response curve to isoprenaline was obtained in pre-contracted tracheal smooth muscle in the presence of three concentrations of aqueous-ethanolic extract, propranolol and saline. Values of EC50 (the effecti...
