The effect of oxmetidine 800 mg/day, a new histamine H2-receptor antagonist, on duodenal ulcer healing was compared with cimetidine 1000 mg/day in a two-centre double-blind trial. Ninety-nine patients completed the study. After four weeks, ulcers were healed in 74% of the cimetidine-treated patients and in 78% of the oxmetidine-treated patients (p greater(More)
Combined treatment with cimetidine 1 g daily and cisapride 40 mg daily in patients with endoscopically diagnosed severe reflux oesophagitis was compared with single drug therapy (cimetidine and placebo). At the end of the six to 12 weeks treatment, 11 (46%) of the 24 patients under single drug therapy were endoscopically healed and three were improved. In(More)
The purpose of this single blind controlled multicentre trial was to compare the relative effectiveness of pirenzepine and cimetidine in healing endoscopically proven duodenal ulcers. One hundred and twenty six patients with duodenal ulcer were treated with a daily dose of 100 mg pirenzepine (50 mg each before breakfast and before the evening meal), and 128(More)
Lacunar lesions are small infarctions in the territory of small penetrating arteries of the brain. Because of their small size these lesions can only in part be detected by CT. Clinical symptoms do not always correspond with the lesions visible in the CT. We studied the somatosensory evoked potentials (SEP), the visual evoked potentials (VEP) and the(More)
We report the case of a 66-year-old woman who had a hysterectomy because of uterine tumour. Histological examination showed a leiomyoma with degenerative changes and extensive extramedullary haematopoiesis. There was no evidence of any haematological or systemic disease. Extramedullary haematopoiesis in patients without haematological disorders is very rare(More)
The aim of this article is to find a new experimental text processing model based on mechanisms underlying human brain’s neural processing. A considerable possibility of building such model is reexamining of Shank’s Conceptual Dependency Theory and Story Understanding. We are offering a new approach to the text processing based on Conceptual Dependency(More)
