Objective. The objective of this study was to find out the possible antiulcer mechanism of action of Eremomastax speciosa. Method. Carbachol- and histamine-induced hypersecretion, associated with the pylorus ligation technique, were used in rats. Gastric mucosal ulceration, mucus production, pH, gastric volume, and acidity were measured. Results. Histamine and carbachol raised gastric acidity t...

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...

Ulceration of the gastric pars oesophagea is a common problem in intensive pig production that is often detected at slaughter. A survey was carried out at the Pietersburg abattoir in the Northern Province during a 6-month period. In total, 4320 pig stomachs were examined. Gastro-oesophageal ulcers were observed in 5.1% of the stomachs, gastric erosion in 15.2%, and hyperkeratosis in 18.9%. Time...

Recent reports of cytomegalovirus associated colonic and oesophageal ulceration in immunosuppressed patients infected with the human immunodeficiency virus, have focused attention on the possibility that viral infections may in some cases be the initial insult which leads in susceptible subjects to gastrointestinal ulceration. In this case report we describe how systemic primary infection with ...

The anti-ulcerogenic effects of Solanum indicum var. distichum alcoholic extract on aspirin and ethanol induced ulceration in rats with respect to antioxidant status in the gastric mucosa have been investigated. Animals were divided into two main classes, alcohol injury group and aspirin injury group and then each of them was classified into seven subgroups including controls administered salin...

An antibody precipitating urease was found in 171 out of 180 human sera. Data obtained on limited material (50 cases) suggest that the anti-urease titre is appreciably higher in the serum of patients suffering from gastric ulcer. This is a pointer towards a possible antigen-antibody mechanism in the genesis of chronic gastric ulceration.

A 50-year-old female patient complained about watery diarrhea for two weeks. Because of back pain nonsteroidal antirheumatics had been prescribed for months before. The endoscopic and radiologic investigation demonstrated a large gastrocolic fistula due to NSAID-induced gastric ulceration and an acid-induced colitis in the transverse colon. Treatment consisted in partial gastric resection and r...
