Effect of molecular structure on bile acid-induced alterations in absorptive function, permeability, and morphology in the perfused rabbit colon.
It is shown that of the major primary and secondary bile acids in man, only deoxycholic and chenodeoxycholics acids alter colonic structure and function in the rabbit and that bile acid-induced secretion was invariably associated with increased mucosal permeability and epitheliolysis. Expand
Capacity of the human colon to absorb fluid
Abstract To measure the maximum amount of fluid that can be absorbed by the normal human colon, 4 healthy subjects were studied by metabolic balance. When, in addition to normal dietary intakes, 2Expand
Perfusion of rabbit colon with ricinoleic acid: dose-related mucosal injury, fluid secretion, and increased permeability.
Dose-related changes in net fluid transport and mucosal permeability were also associated with ricinoleate perfusion, and structural and functional alterations may contribute to intraluminal accumulation of fluid and catharsis that can result from administration of ricinolesic acid (castor oil).

Quantification of Helicobacter pylori infection in gastritis and ulcer disease using a simple and rapid carbon-14-urea breath test.
In H. pylori positive patients, breath 14CO2 was found to be similar in patients with and without ulcer disease, suggesting that the number of bacteria is not a determining factor for the onset of ulceration. Expand

Gastric ulcers and Helicobacter heilmannii
Ulcers differ from those associated with H. pylori infection or with the use of NSAIDs, suggesting that H. heilmannii is a possible cause of gastric ulcers. Expand
Are perforated gastroduodenal ulcers related to Helicobacter pylori infection?
It is concluded that patients with perforated ulcers are a heterogeneous group with a recurrent ulcer disease mainly in patients with Helicobacter pylori. Expand
Touch cytology. A quick, simple, sensitive screening test in the diagnosis of infections of the gastrointestinal mucosa.
Cytology was the only positive test in eight, nine, four, seven, and eight patients, respectively, and increased thus the diagnostic yield obtained by histologic examination. Expand
Absorption of nutrients in lactase deficiency
The nutritional consequences of malabsorption in association with primary lactase deficiency in adults are probably minimal and more fluid and nutrient was recovered from the ileum in lactase-deficient subjects after whole milk than in control subjects or in lactases deficiency after hydrolyzed milk.

[Hypersensitivity interstitial pneumopathy and ulcero-hemorrhagic rectocolitis: role of methotrexate].
The case of a 46-year-old man with refractory ulcerative colitis treated with methotrexate who was admitted in the hospital for asthenia, fever, cough and dyspnea and transferred to the intensive care unit due to the development of adult respiratory distress syndrome. Expand
