Orally ingested non-steroidal anti-inflammatory drugs (NSAIDs) and acid in gastric secretions are gastric irritants that co-exist at the surface of the gastric mucosa. Here, we examined the individual and combined effects of indomethacin, a typical NSAID, and hydrochloric acid on cell death in primary cultures of guinea pig gastric mucosal cells. Indomethacin alone (at concentrations less than ...

The aim of this work was to study the ability of beta-cyclodextrin (beta-CD) or hydroxypropyl beta-cyclodextrin (HP-beta-CD) to ameliorate the induction of gastric ulcers by a nonsteroidal anti-inflammatory drug, indomethacin or piroxicam, in rats exposed to restraint and hypothermic stress at 4 degrees C. Using oral gavage, rats fasted for 72 h were administered the equivalent of a 100 mg/kg d...

Spathodea falcata is used in Indian folk medicine as an antiulcerogenic agent. This study was intended to evaluate the antiulcer property of various extracts of bark of Spathodea falcata at different dose levels in ethanol induced and indomethacin induced gastric ulcer models. It was observed that oral administration of all the extracts shows significant reduction in ulcer lesion index as well ...

ABSTRACT Introduction: Formation of gastric ulcer is a multifactorial process so that vascular changes, mucous secretion, gastric acid and gastrointestinal tract mucous biochemistry are involved in gastric ulcers. Despite therapeutic properties, ibuprofen as a non-steroidal anti-inflammatory drug (NSAID) can cause mucosal lesions in the stomach. In this study, the effect of Matri...

BACKGROUND AND PURPOSE Acemetacin is a non-steroidal anti-inflammatory drug which is rapidly bioconverted to indomethacin, but produces significantly less gastric damage than indomethacin. This study was performed to investigate several possible mechanisms that could account for the gastrointestinal tolerability of acemetacin. EXPERIMENTAL APPROACH The gastric and intestinal damaging effects ...

purpose: to compare the prevalence of glaucoma among peptic ulcer patients with or without helicobacter pylori infection. methods: among 352 patients with an indication of gasterointestinal endoscopy for peptic problems, 120 patients in 18-88 years of age were included for evaluation of glaucoma. according to the results of histopathologic and urease test, they were divided into two groups: hel...

Neutrophil adherence within the gastric microcirculation is thought to be a major step in the pathogenesis of gastric mucosal damage induced by indomethacin. Pentoxifylline, a methylxanthine derivative, prevents leukocyte adherence to vascular endothelium and protects organs from shock by reducing tumour necrosis factor alpha (TNF alpha) concentrations. Rats were treated with 20 mg/kg oral indo...
