Ellagitannins have shown anti-inflammatory and anti-Helicobacter pylori properties; however, their anti-inflammatory activity at gastric level was not previously investigated. The aim of this research was to evaluate the effects of ellagitannins from Rubus berries on gastric inflammation. Ellagitannin enriched extracts (ETs) were prepared from Rubus fruticosus L. (blackberry) and Rubus idaeus L...

OBJECTIVE To investigate the preventive and therapeutic effects of Danshen Decoction on gastric ulcer in experimental animal models. METHODS The model of water immersion restraint stress ulcer in mice, and the models of acetic acid impaired gastric ulcer and pyloric ligation gastric ulcer in rats were established. The total gastric acid, the activity of pepsin and the amount of gastric wall b...

Previous studies have demonstrated that the gastric mucosa of diabetic rats is highly vulnerable to acute injury but the influence of nonsteroidal anti-inflammatory drugs (NSAID) and their new nitric oxide (NO) releasing derivatives of aspirin (NO-ASA) on the ulcer healing under diabetic conditions has been little studied. In this study streptozocin (STZ, 70 mg/kg injected intraperitoneally) wa...

Ethanol extract of Buchholzia coriacea seed was evaluated for anti-ulcer as well as anti-secretory activity in rats because of its use in Nigerian folk medicine as an anti-ulcer agent. Standard pharmacological methods were used to carry out phytochemical analysis of the plant. Quantitative phytochemical analysis of the ethanol extract of B. coriacea revealed the presence of alkaloids (101.88 ± ...

The literature, and particularly the statistical evaluation of peptic ulcer, is vast and ordinarily there should be little excuse for adding to it, unless one has some definite reason. It is well recognized that all over the world this disease pattern in the last few decades has undergone certain changes with regard to the duodenal-gastric ulcer ratio, sex incidence, and the occurrence of compl...

In this study, the anti-inflammatory and anti-ulcerative effects of metyrosine, a selective tyrosine hydroxylase enzyme inhibitor, were investigated in rats. For ulcer experiments, indomethacin-induced gastric ulcer tests and ethanol-induced gastric ulcer tests were used. For these experiments, rats were fasted for 24 h. Different doses of metyrosine and 25 mg/kg doses of ranitidine were admini...

Helicobacter pylori is an important risk factor for gastric cancer, gastric ulcer, and duodenal ulcer, yet most infected persons do not develop disease. We examined two correlates of acquisition age, sibship size and birth order, to evaluate the hypothesis that early life acquisition of //. pylori is a risk factor for the development of these illnesses. In earlier nested case-control studies of...

Anti gastric ulcer activity of root, stem and leaves of Amaranthus spinosus Linn. was studied against ethanol, hydrochloric acid, indomethacin, stress and pyloric ligation induced gastric ulceration in albino rats. Omeprazole was used as standard anti gastric ulcer drug. Significant anti gastric ulcer activity was noted in root, stem and leaves of Amaranthus spinosus Linn. Root of the plant, ho...
