Effects of Propranolol

چکیده
In this study we assessed the effects of ,3-adrenergic blockade on cardiac function during exercise. First-pass radionuclide angiography was used to measure left ventricular ejection fraction (LVEF), cardiac output (CO), end-diastolic volume (EDV), end-systolic volume (ESV), stroke volume (SV) and pulmonary transit time (PTT) in 12 normal young men. Studies were first performed at rest and during upright bicycle exercise after 2 days of oral administration of propranolol 320 mg/day. A minimum of 48 hours after cessation of propranolol, hemodynamic measurements were made at rest, during exercise at the same heart rate achieved

متن کاملThe Effect of Oral Propranolol versus Oral Corticosteroids in Management of Pediatric Hemangiomas
BACKGROUND Hemangiomas are the most common benign tumors of infancy. This study evaluated the efficacy of oral propranolol comparing to oral steroids in management of pediatric hemangiomas. METHODS In North India from January 2012 to January 2015, sixty children <6 years old with superficial hemangiomas were divided into 2 groups; oral propranolol vs. oral prednisolone. All participants we...
متن کاملEffect of Propranolol on Angiogenic Factors in Human Hematopoietic Cell Lines in vitro
Background: Beta-adrenergic blocking agents have been broadly used for treatment of many cardiovascular diseases such as arterial hypertension and ischemic heart failure. Anti-tumoral, anti-inflammatory and anti-angiogenesis effects of propranolol (a non-selective beta-adrenergic blocker) have been shown. Angiogenesis (replenish of the pre-existing vascular networks) plays a critical role in s...
متن کاملEffects of histidine and vitamin C on isoproterenol-induced acute myocardial infarction in rats
In the present study, we investigated the effects of histidine and vitamin C (alone or in combination) treatments against isoproterenol (a β-adrenergic receptor agonist)-induced acute myocardial infarction in rats. We used propranolol (a β-adrenergic receptor blocker) to compare the results. Rats were given intraperitoneal injections of histidine (40 mg kg-1) and vitamin C (40 mg kg<...
متن کاملDecrease of Serum Vascular Endothelial Growth Factor, along with its Ocular Level, after the Periocular Injection of Celecoxib and Propranolol in Streptozotocin-induced Diabetic Mouse Model
Background: There is a direct correlation between ocular vascular endothelial growth factor (VEGF) level and progression of pathological outcomes in diabetic retinopathy. In our previous study, the periocular administration of propranolol and celecoxib could significantly reduce ocular VEGF levels in a diabetic mouse model. Here, we investigated the changes of serum VEGF after ...
متن کاملPropranolol–induced Impairment of Contextual Fear Memory Reconsolidation in Rats: A Similar Effect on Weak and Strong Recent and Remote Memories
Introduction: Previous studies have demonstrated that the &beta-adrenergic receptor antagonist propranolol impairs fear memory reconsolidation in experimental animals. There are experimental parameters such as the age and the strength of memory that can interact with pharmacological manipulations of memory reconsolidation. In this study, we investigated the ability of the age and the strength o...
