Acta méd. colomb; 41 (4), 2016
Resumen Introducción: la detección de vasorreactividad pulmonar en hipertensión pulmonar es importante para determinar el beneficio del tratamiento con calcioantagonistas a largo plazo. En los últimos años se ha utilizado el iloprost como alternativa para la realización de la prueba con buenos res...

A prospective, randomized, single - blind study comparing intraplaque injection of thiocolchicine and verapamil in Peyronie's Disease: a pilot study

Int. braz. j. urol; 42 (5), 2016
ABSTRACT Objectives: To compare the response to tiocolchicine and verapamil injection in the plaque of patients with Peyronie's disease. Materials and Methods: Prospective, single-blind, randomized study, selecting patients who have presented Peyronie's disease for less than 18 months. Thiocolchicine 4...

Levobupivacaine induces vasodilatation, but not vasoconstriction, in rat mesenteric artery

Introduction: Levobupivacaine (LEVO) can replace analgesia because it exhibits low toxicity and causes minor vasoconstriction, enabling its use in patients in whom vasoconstrictors are contraindicated. Objective: We aimed to evaluate the effects of LEVO in isolated rat superior mesenteric artery by usin...

Jabuticaba-Induced Endothelium-Independent Vasodilating Effect on Isolated Arteries

Arq. bras. cardiol; 107 (3), 2016
Abstract Background: Despite the important biological effects of jabuticaba, its actions on the cardiovascular system have not been clarified. Objectives: To determine the effects of jabuticaba hydroalcoholic extract (JHE) on vascular smooth muscle (VSM) of isolated arteries. Methods: Endothelium-denu...

Sobrevida a mediano plazo en los pacientes con hipertensión arterial pulmonar en la era de terapias vasodilatadoras específicas del territorio vascular pulmonar

Rev. méd. Chile; 144 (7), 2016
Background: Pulmonary arterial hypertension (PAH) is a rare and progressive disease. Long-term survival remains poor despite of advances in specific vasodilator therapy. Aim: To describe the survival rate in a cohort of PAH patients in two referral centers in Chile. Patients and Methods: One hundred fift...

Tratamiento anticoagulante y vasodilatador para el síndrome de Nicolau tras la administración de una inyección de bencilpenicilina benzatínica intramuscular a un niño de cuatro años de edad

Arch. argent. pediatr; 114 (3), 2016
El síndrome de Nicolau (SN) es una complicación rara de la inyección de ciertos fármacos por vía intramuscular, intrarticular o subcutánea, que produce necrosis isquémica de la piel, las partes blandas y el tejido muscular circundante. La bencilpenicilina benzatínica es uno de los antibióticos m...

The Labdane Ent-3-Acetoxy-Labda-8(17), 13-Dien-15-Oic Decreases Blood Pressure In Hypertensive Rats

Arq. bras. cardiol; 106 (6), 2016
Abstract Background: Labdane-type diterpenes induce lower blood pressure via relaxation of vascular smooth muscle; however, there are no studies describing the effects of labdanes in hypertensive rats. Objective: The present study was designed to investigate the cardiovascular actions of the labdane-ty...

Effect of Nebivolol on MIBG Parameters and Exercise in Heart Failure with Normal Ejection Fraction

Arq. bras. cardiol; 106 (5), 2016
Abstract Background: More than 50% of the patients with heart failure have normal ejection fraction (HFNEF). Iodine-123 metaiodobenzylguanidine (123I-MIBG) scintigraphy and cardiopulmonary exercise test (CPET) are prognostic markers in HFNEF. Nebivolol is a beta-blocker with vasodilating properties. Ob...

The possible protective effects of dipyridamole on ischemic reperfusion injury of priapism

Int. braz. j. urol; 42 (1), 2016
ABSTRACT Purpose To investigate the protective effects against ischemia reperfusion injury of dipyridamole in a model of induced priapism in rats. Materials and Methods Twenty-four male Sprague-Dawley rats were divided into four groups, control, P/R, P/R+DMSO and P/R+D. 3ml blood specimens were colle...

Deficiency of sex hormones does not affect 17-ß-estradiol-induced coronary vasodilation in the isolated rat heart

Braz. j. med. biol. res; 49 (5), 2016
The relaxation of coronary arteries by estrogens in the coronary vascular beds of naive and hypertensive rats has been well described. However, little is known about this action in gonadectomized rats. We investigated the effect of 17-ß-estradiol (E2) in coronary arteries from gonadectomized rats, as we...
