There is no ideal method for detecting Helicobacter pylori. The 'standard' 13Carbon urea breath test (13C-UBT), which involves collecting eight to 15 breath samples and subsequent costly analysis, was modified by pooling 21 samples of expired breath taken at five minute intervals for 40 minutes into a collecting bag, from which a single 20 ml aliquot was(More)
The efficacy of two doses of balsalazide for the maintenance of remission in patients with ulcerative colitis was compared in a double-blind multicentre trial. Sixty-five patients received a 2 g daily dose, and 68 a 4 g dose. The patient groups were similar at entry for sex, age, and disease distribution. Clinical assessment was carried out at 3-monthly(More)
BACKGROUND Survival of Helicobacter pylori is dependent upon urease in the cytoplasm and at the bacterial surface. We have sought to clarify how alkaline ammonium salts, released from urea by this enzyme, might alter mucus pH and so affect growth and motility of the bacterium in the gastric mucus environment. METHODS Experiments were conducted in vitro to(More)
A double blind trial of prednisolone suppositories in out-patients with idiopathic proctitis is reported. Significant improvement was noted. When prednisolone suppositories were given after the patient had already used suppositories of base alone for three weeks the active treatment was no longer so effective.
Omeprazole is a powerful inhibitor of gastric acid and may suppress Helicobacter pylori by effecting the pKa of H pylori urease, by altering the pattern of infection, or by promoting overgrowth of other bacteria. At routine endoscopy H pylori was detected by histology and culture before and after four weeks' treatment with omeprazole, 40 mg each morning. A(More)
