Cyclooxygenase-1 (COX-1) has been regarded as a constitutively expressed enzyme that generates prostaglandins for gastrointestinal integrity. We attempted to clarify the association between potentially functional polymorphisms (T-1676C and A-842G/C50T) in the COX-1 gene promoter and gastroduodenal disorders in a Japanese population. The study was performed with 480 stocked DNAs from subjects (g...

Aloe buettneri A. Berger is commonly used in traditional Togolese medicine to treat inflammatory and gastric ulcers. The present study examined the gastro-protection effect of the hydro-alcoholic extract of A. buettneri on mucus production and gastric pH. A gastric ulcer is induced by ethanol 95° alone (1 mL/kg body weight), after pre-treatment with indomethacin (300 mg/kg) or by utilising L-NA...

BACKGROUND The relation between Helicobacter pylori infection and non-steroidal anti-inflammatory drug (NSAID)-associated peptic ulcers remains unclear; in particular, it is not known whether H pylori plays a part in the healing and recurrence of these ulcers. AIMS To evaluate prospectively in a consecutive series of arthritis patients receiving longterm NSAID treatment the prevalence of pept...

The objective of this study was to investigate the prevalence of gastric mucosal injury induced by nonsteroidal anti-inflammatory drugs (NSAIDs) in patients with rheumatoid arthritis (RA). Upper gastrointestinal endoscopy was performed on 100 RA patients treated with NSAIDs. Patient factors potentially contributing to the development of NSAID-induced gastric mucosal injury were identified by lo...

BACKGROUND Basic fibroblast growth factor (bFGF) promotes angiogenesis and healing of gastric ulcers in rats, and bFGF expression is up regulated in such ulcers. However, little is known about expression of bFGF in human gastric mucosa. AIMS To investigate bFGF expression in intact human gastric mucosa and gastric ulcers and to determine whether low bFGF content or altered binding by mucosa i...

The importance of prostaglandin E(2) in various pathophysiological events emphasizes the necessity of understanding the role of PGE synthases (PGESs) in vivo. However, there has been no report on the functional relevance of microsomal PGES-1 (mPGES-1) to the physiological healing processes of gastric ulcers, or to angiogenesis, which is indispensable to the healing processes. In this report, we...

Gastric ulcers were found in 10 of 114 blue marlin, Mu&uim nigricuns, and 2 of 3 black marlin, M. indica, examined from 1%7 to 1969 at the Hawaiian International Billfmh Tournament. Parasitic nematodes were found imbedded in the base of ulcers in one blue marlin and two black marlin. The gross and microscopic morphology of the ulcers is given and possible causes are discussed. The most likely c...

AIM: To determine the prevalence of antralization at the edge of proximal gastric ulcers, and the effect of H. pylori eradication on the mucosal appearances. METHODS: Biopsies were taken from the antrum, body and the ulcer edge of patients with benign proximal gastric ulcers before and one year after treatment. Gastric mucosa was classified as antral, transitional or body type. H. pylori positi...

Gastric ulcer is a serious condition that results from the wearing/tearing of stomach mucosa. A physiological equilibrium maintained between mucosal defense and aggressive factors. In this study, effectiveness medicinal plants (Hypericum perforatum) in management gastric was compared to omeprazole, well-known drug for ulcer. This study involved numerous groups male rats comprising following: fi...

BACKGROUND To analyze risk factors associated with gastro-duodenal ulcers and erosions in children. METHODS Open, prospective, multicenter, case-control study carried out in 11 European countries in patients with gastric or duodenal ulcers/erosions and 2 age-matched controls each. Possible risk factors were recorded. Logistic regression models were performed with adjustment for centers and ag...
