1. The aim of this study was to investigate the effect of sertraline, a selective serotonin re-uptake inhibitor, on contractile responses to noradrenaline (NA), KCl, serotonin (5-HT) and electrical field stimulation of rat isolated vas deferens. 2. Pre-treatment with 10(-4) M sertraline showed inhibitory effects on responses to NA, KCl, 5-HT and electrical(More)
PURPOSE To determine the toxicity and clinical effectiveness of accelerated superfractionated radiotherapy with delayed concomitant boost (ASCBRT) in locally invasive carcinoma of the bladder. METHODS AND MATERIALS Between July 1997 and December 2001, 87 patients (unsuitable or refusing cystectomy) with invasive bladder cancer underwent ASCBRT. The mean(More)
Selective serotonin reuptake inhibitors are used in the treatment of psychiatric disorders but are associated with high incidence of sexual dysfunction such as ejaculation disorders by sertraline and fluoxetine, erection disorders by paroxetine. The aim of this study is to evaluate the effects of paroxetine, sertraline and fluoxetine on relaxation of smooth(More)
RATIONALE AND OBJECTIVES MR findings of renal vein thrombosis are not consistent in the literature. Our goal was to evaluate MR findings of kidneys after renal vein occlusion in dogs. METHODS Surgical ligation of renal veins was performed in seven dogs. Of these, five dogs were examined with MRI before surgery, on the day of the renal vein ligation, and(More)
Massive retroperitoneal haemorrhage because of adrenal bleeding following blunt trauma is a rare entity. We describe a 23-year-old woman with massive retroperitoneal haemorrhage as a result of inferior adrenal artery (IAA) disruption following a car accident. Superselective transcatheter embolization of the IAA using polyvinyl alcohol particles was(More)
Digoxin inhibits the membrane-bound ATPase enzyme, resulting in a rise in intracellular sodium and activated outward potassium current, predisposing to arrhythmias. In this study, the effect of ketanserin, thought to block outward potassium currents, was investigated on digoxin-induced arrhythmias. Twenty-four guinea-pigs were studied in four groups(More)
Previous experiments with rat isolated vas deferens have shown that sertraline pretreatment inhibits contractile responses to noradrenaline, KCl, serotonin and electrical field stimulation. In the present study, the aim was to investigate the effects of long-term use of sertraline on contractile responses of rat isolated vas deferens. Fifteen Sprague-Dawley(More)
The aim of the present study is to evaluate whether paroxetine (a selective serotonin re-uptake inhibitor) can modify the contractile responses of isolated vas deferens. Some contractile agents, potassium chloride (KCl), adenosine 5'-triphosphate (ATP), noradrenaline (NA), and electrical field stimulation (EFS) caused contractions both in epididymal and(More)
