BACKGROUND Pulmonary hypertension secondary to congenital heart disease is a common problem in pediatric patients presenting for open heart surgery. Milrinone has been shown to reduce pulmonary vascular resistance and pulmonary artery pressure in pediatric patients and neonates postcardiac surgery. We aimed to evaluate the postoperative outcome in such patients with three different fixed mainte...

The purpose of this study was to test the hypothesis that oral administration of a low dose of practolol in man produces selective beta-1 receptor blockade, whereas oral administration of a high dose blocks both beta-1 and beta-2 receptors. Normal men were studied 2-4 h after a single oral dose of practolol (1.5 or 12 mg/kg) and after placebo. Effects on beta-1 receptors were studied by measuri...

BACKGROUND Chemotherapy plus radiotherapy is the standard of care for patients with limited stage Hodgkin lymphoma (HL). Radiotherapy is evolving from involved field radiotherapy (IFRT) to involved node radiotherapy (INRT) to decrease radiotherapy-related morbidity. In the absence of long-term toxicity data, dose-volume metrics of organs at risk (OAR) provide a surrogate measure of toxicity ris...

Abstract Purpose The exposition of cardiac conduction system during breast radiation therapy has never been studied, despite the increasing use intensity-modulated therapy, which exposes larger volume to low-dose bath. We evaluated node exposure irradiation with volumetric modulated arc and estimated potential dosimetric benefit proton therapy. Materials Methods Atrioventricular (AVN) sinoatria...

objective: the study was conducted to evaluate cardioprotective effect of silk cocoon (abresham) bombyx mori (b. mori) on isoprenaline-induced myocardial infarction. this study deals with the cocoons, which is called abresham in the unani system of medicine. it is one of the 64 drugs which avicenna has mentioned in avicenna’s tract on cardiac drugs and used in the treatment of cardiovascular di...

background: ketamine is the only anesthetic agent that leads to an increase of blood pressure and heart rate by activation of sympathetic nervous system. however, there is a controversy about this effect of ketamine especially if used in small dosage. we proposed to evaluate the hemodynamic effect of small dose of ketamine during phacoemulsification. methods: one hundred patients of asa physica...

abstract background: doxorubicin is used in treatment of many solid malignancies and lymphomas with poorly understood mechanism underlying tissue injury. rosemary leaves or extracts were found to contain high antioxidant activity almost equivalent to bha (butylated hydroxy anesole) and bht (butylated hydroxy toluene). thus, the possibility of aqueous rosemary leaves extract (re) to ameliorate d...
