The variations between different lots of activated partial thromboplastin time (APTT) produced by three major North American suppliers were evaluated over the past eight years. The authors found significant variations between the heparin sensitivity of the APTT reagents produced under the same name by the same supplier. The variations were so much that,(More)
AIMS To compare gastric acid suppression by netazepide, a gastrin/CCK2 receptor antagonist, with that by a proton pump inhibitor (PPI), and to determine if netazepide can prevent the trophic effects of PPI-induced hypergastrinaemia. METHODS Thirty healthy subjects completed a double-blind, randomized, parallel group trial of oral netazepide and(More)
The aim of this study was to investigate the protective action of a new compound, ranitidine bismuth citrate, in the prevention of aspirin-induced acute mucosal injury to the upper gastrointestinal tract of healthy human volunteers. In a double-blind randomized three-way cross-over study 24 male volunteers received placebo, 900 mg aspirin or 900 mg aspirin(More)
Nicotinic acetylcholine receptor protein has been purified from foetal and adult skeletal muscle by extraction in non-ionic detergent followed by purification on immobilised α-toxin. Purified foetal and adult receptors focused as single, sharp peaks whether directly labelled with (125)I or indirectly labelled with (125)I-α-bungarotoxin. Polyacrylamide gel(More)
The aim was to study the development of human small intestinal microvillus membranes. We compared the protein patterns of human fetal and adult small intestinal microvillus membranes using the high-resolution technique of sodium dodecyl sulphate-polyacrylamide gel electrophoresis. We also examined the synthesis of brush border membrane proteins from the(More)
The in vitro effect of heparin on platelet aggregation was studied in three groups: in 26 subjects recently treated with heparin, in 18 subjects on maintenance hemodialysis, and in 20 normal controls. With the aid of Technicon H6000, platelet counts and platelet aggregations were compared in whole blood samples collected in ethylenediaminetetraacetic acid(More)
Cefuroxime axetil 250 mg twice daily and amoxycillin 250 mg three times daily were compared in an investigator-blind, randomised, parallel group, multicentre study of acute or acute-on-chronic bronchitis. The two compounds had broadly similar efficacy. Analysis of patients on an intention-to-treat basis 24-72 hours after completion of the course of study(More)
