In a prospective study in 1224 patients referred for upper alimentary endoscopy, reflux oesophagitis was found in 195 (16%) of the patients and hiatus hernia in 249 (20%). In patients with reflux oesophagitis a coexisting hiatus hernia was found in 68%. The weight-for-height index (W/H1.8), which expresses the degree of overweight, was significantly higher(More)
Comparative pharmacologic studies have indicated that the cardiac beta 2 adrenoceptors of vertebrate species are "adrenaline" receptors; i.e., the distribution of beta 2 receptors in the heart seems to be related to the amounts of adrenaline in the sympathetic nerves and in the circulation, and the beta 2 receptors seem to be stimulated mainly by(More)
In absence of beta-receptor blocking agents, alpha-adrenergic inotropic effects could be demonstrated in the rat myocardium for the synthetic alpha-agonists phenylephrine and methoxamine, but not for the naturally occurring catecholamines, adrenaline and noradrenaline. Other synthetic alpha-agonists were without effects. In the presence of the beta-receptor(More)
One hundred and thirty-seven consecutive outpatients with non-ulcer dyspepsia (NUD) and erosive prepyloric changes (EPC) were randomly allocated to double-blind treatment with 400-micrograms misoprostol tablets twice daily or placebo for 4 weeks. Misoprostol had a significant worsening effect on epigastric pain, nausea, meteorism, lower abdominal pain, and(More)
Functional beta-adrenoceptor populations in the human heart were studied in vitro in electrically-paced strips of the right auricular and ventricular myocardium. The relative potency of selected agonists in producing inotropic responses (Tmax, T'max) in the presence of blockers for neuronal and extraneuronal uptakes was found to be as follows: isoprenaline(More)
Inotropic effects via cardiac alpha-adrenoceptors were studied in electrically driven auricular strips (1 Hz, 37 degrees C) from patients treated with beta-blockers for months prior to open heart surgery. Marked alpha-mediated positive inotropic effects were demonstrated with adrenaline (A), noradrenaline (NA) and phenylephrine (PHE) in the presence of(More)
The etiology of chronic fatigue syndrome (CFS)/myalgic encephalomyelitis (ME) is unknown. In Norway, a vaccine against Neisseria meningitides group B was administered to teenagers in 1988--1989 in a protection trial. In order to estimate the relative risk of CFS/ME according to vaccine history, we conducted a case-control study in 2007, with 201 cases(More)
