The Role of Nitric Oxide and Prostaglandins in the Effect of Adenosine on Contractility, Heart Rate and Coronary Blood Flow in Guinea Pig Isolated Heart
It is a well-established fact that adenosine and its receptor subtypes (A 1 and A ) are involved in changes of contractility, heart rate and coronary blood flow (CBF) under different circumstances. This study was conducted to evaluate the role of nitric oxide and prostaglandins in development of these changes. For this purpose, Nitro-L-Arginine methyl ester (L-NAME), and indomethacin as inhibit...
متن کاملThe 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 کاملEffect of Aqueous-Ethanolic Extract from Rosa damascena on Guinea Pig Isolated Heart
Objective(s) In the present study, the effects of aqueous-ethanolic extract from Rosa damascena on heart rate and contractility were examined. Materials and Methods Isolated guinea-pig hearts were perfused through aorta in a Langendorff mode. Heart rate (HR) and contractility were determined in the presence of four concentrations of the extract (0.1, 0.2, 0.4 and 1.0 mg %) and isoprenaline (...
متن کاملEffects of 4-(2-Alkylthio-1-benzyl-5-imidazolyl)-Dihydropyridines on the Isolated Rat Colon and Right Atrium Contractility
Objectives In order to provide a pharmacological profile for some newly synthesized dihydropyridines, we investigated their effects on the isolated rat colon segments and the isolated rat atrium contractility. The tested compounds include alkyl ester analogues of nifedipine, in which the ortho-nitrophenyl group at position 4 is replaced by 2-alkylthio-1-benzyl-5-imidazolyl substituent, and nif...
متن کاملEFFECTS OF EPIDURAL ANALGESI A WITH LOW-DOSE BUPIVACAINE AND FENTANYL ON THE PROGRESS OF LABOR AND MODE OF DELIVERY
Background and Objective: Epidural analgesia (EA) has been used to relieve labor pain in many obstetric units, yet controversy persists about its effect on progress and outcome in labor. The purpose of the current study was to evaluate the effect of EA on the rate of cervical dilation and myometrial contractility. Methods: In a 6-month period, 36 women who received standardized EA were mat...
متن کاملEffect of apelin on cardiac contractility in acute reno-vascular hypertension: The role of apelin receptor and kappa opioid receptor heterodimerization
Objective(s): Apelin/APJ system plays an important role in the regulation of myocardial contractility (MC) and blood pressure. Opioid receptors (OPRs) are also important cardiovascular regulators and exert many of their effects through modulating the function of other systems. This study analyzed the interaction between APJ and kappa OPRs (KOR) in cardiac responsiveness to apelin in acute reno-...
