The aim of the study was to determine if there is a difference between ileal and faecal assays for determining amino acid and N digestibilities in adult human subjects. Comparison of true ileal amino acid and N digestibilities was also made between adult human subjects and growing pigs to establish the usefulness of the pig as a model animal. Five subjects(More)
A high-fiber diet may protect against colon cancer because of the butyrate generated in the colon by bacterial fermentation of nonstarch polysaccharides. Butryrate can reverse neoplastic changes, at least in vitro, and resistant starch (RS) represents a source of butyrate in vivo. We examined the effects of replacing normal maize starch in the diet of rats(More)
The spatial relations between bacteria and the affected tissues can indicate pathogenic mechanisms. This study was undertaken to define the spatial relation of Helicobacter pylori to the human gastric mucosa. Antibodies against gastric mucus and ruthenium red were used to stabilise the glycoprotein structure of the mucus and glycocalyces in antral biopsy(More)
Sucralfate protects the stomach against a number of experimental damaging agents and is efficacious in the treatment of peptic ulcer disease. It binds with acidity to the base of an ulcer to form a protective barrier. Sucralfate also enhances prostaglandin synthesis and release in the mucosa. In this study, the rat stomach was examined to determine(More)
The digestion of cellulose, hemicellulose, and lignin has been investigated in humans. Two groups of subjects were studied--healthy subjects with an ileostomy and normal subjects. Both were put on a fixed diet of known cellulose, hemicellulose, and lignin content. From the feces excreted the fiber components were measured by the acid and neutral detergent(More)
Four-hundred-and-fifty-six patients with ulcerative colitis (UC) and 137 patients with Crohn's disease (CD) attended public hospitals within Auckland between 1969 and 1978. Polynesians comprised 15% of the population at risk but accounted for only 0.4% of UC cases and no CD cases. Annual incidence rates were 5.4/100,000 Caucasians for UC and 1.75 for CD. CD(More)
Rat jejunal disaccharidases were measured after feeding high fat fibre-free, high fat pectin, high fat cellulose, high fat galactomannan and high fat tannin diets for 27 weeks. Compared with the high fat fibre-free diet, pectin lowered both lactase and sucrase levels (p less than 0.025). Galactomannan and tannin lowered only the lactase level (p less than(More)
Two patients with hemobilia are presented. The first patient, with alcoholic liver disease, had a percutaneous liver biopsy. Subsequently he developed jaundice, with an enlarged tender gallbladder, biliary colic, and gastrointestinal bleeding. Hemobilia was demonstrated by superselective hepatic angiography and bleeding was stopped by intraarterial infusion(More)
Changes in the plasma and urine levels of the trace metal zinc have been followed in a series of 37 adult patients totally supported by intravenous alimentation. Copper has also been determined in more recent cases. In such a seriously ill group, although urinary zinc loss may be very high at the height of catabolism, severe plasma depletion does not occur(More)
