Effects of endotoxin on the motility, the permeability of mesenteric blood vessel and endogenous substances (electrolyte (Na, K), histamine, serotonin and primary prostaglandin) in the small intestine of mice were investigated. Diarrhea was induced by intraperitoneal injection of Salmonella typhosa
In experiments with rats exposed to 200 Gy radiation it was shown that the diarrhea effect of serotonin under the effect of radiation is implemented via D- and M-type receptors, and that of histamine via H1 and H2 receptors. Serotonin and histamine, that were released under the effect of radiation
Regional changes in concentrations of histamine (HA), serotonin (5-HT) and 5-hydroxyindoleacetic acid (5-HIAA) in the rat brain were investigated after diarrhea induced by castor oil. Significant decreases in body weight were observed from the 3rd day after daily oral administration of castor oil
Effects of various cathartics on charcoal transport, permeability of blood vessels and biogenic amines (serotonin (5-HT), histamine (His), polyamines) in the small intestine of mice were investigated. Diarrhea was induced in mice by oral administration of magnesium sulfate, mannitol, dioctyl sodium
BACKGROUND
Ebastine is a long-acting, second-generation, selective histamine H1-receptor antagonist. A fast-dissolving tablet formulation of ebastine has been developed at 10- and 20-mg doses, with the intention of facilitating administration to patients experiencing problems with swallowing,
Metiamide an histamine H2-receptors antagonist has been used to treat a case of Zollinger-Ellison syndrome characterized by a long standing diarrhea, an important gastric hypersecretion and a moderatly elevated plasma gastrin but without digestive ulceration. At the dose of 600 mg per day, Metiamide
Histamine in food may be responsible for some cases of food intolerance. We previously demonstrated disturbances in the metabolism of ingested histamine in patients with chronic urticaria (CU) and proposed that this could be related to increased intestinal permeability to histamine. The present
Continuous treatment of three Zollinger-Ellison patients with histamine H2-receptor antagonists for 14, 26 and 31 months resulted in effective relief of complaints and marked reduction in gastric acid secretion. In one of the patients the dose of cimetidine had to be doubled after 15 months of
BACKGROUND
Proton-pump inhibitors (PPI) and histamine-2 receptor antagonists (H2RA) are common acid suppressants used in gastrointestinal disorders. The trend of usage in Malaysia has changed from predominantly H2RA to PPI from 2007 to 2008, 3.46 versus 2.87 and 2.99 versus 3.24 DDD (Defined Daily
Lower gastrointestinal tract symptoms occur frequently in runners. The most common complaints are bowel urgency and diarrhea. Many etiologies have been proposed, including enteric fluid and electrolyte imbalance, autonomic nervous system stimulation, ischemia and mechanical trauma. The evaluation
The mechanisms by which bacterial enterotoxins cause secretory diarrheas have been well defined, and the definitions of such mechanisms have been important in developing a consistently successful therapeutic approach. The less common secretory diarrheas, caused by the interaction of hormones of
The objective of this study was to evaluate the effects of antimicrobial drug use, gastric acid-suppressive agent use, and infection control practices on the incidence of Clostridium difficile-associated diarrhea (CDAD) in a 426-bed general teaching hospital in Northern Ireland. The study was
H2-Histamine receptor blocking agents metiamide and cimetidine were assessed in seven patients with Zollinger-Ellison syndrome (serum gastrin greater than 300 microgram/ml, basal acid output greater than 15 meq/h, ratio of basal acid output to maximal acid output greater than 0.5). Intravenous or
