The roots of Dipsacus asper (DA) have been used as a tonic and analgesic agent in traditional Chinese medicine for the treatment of osteoporosis, low back pain, knee pain, and as an anti-inflammatory agent. Few studies have reported pharmacological gastric activities. In this study, we investigated the effects of dipsacussaponin C (DSC) and 70% ethanol and water extracts of DA on gastritis and ...

Metastasis is a major cause of cancer-related mortality in patients with gastric cancer. Ursolic acid, a pentacyclic triterpenoid compound derived from medicinal herbs, has been demonstrated to exert anticancer effects in various cancer cell systems. However, to the best of our knowledge, the inhibitory effect of ursolic acid on the invasive phenotype of gastric cancer cells has yet to be repor...

Study was aimed to evaluate the possible antisecretory and antiulcer activity of crude bark extract of Acacia catechu and its action against indomethacin an non steroidal anti inflammatory drug (NSAID) plus pyloric ligation induced gastric ulcers in rats. Administration of crude extract of Acacia catechu (400mg/kg/day p.o.) significantly reduced ulcer index when compared with indomethacin induc...

Introduction: The incidence rate of gastric erosions and ulcers in diabetic patients are higher due to failure of mucosal antioxidant defense and maintain enough blood flow. The present study evaluated the gastro-protective effect of sodium hydrosulfide (NaHS) against indomethacin-induced gastric lesions in diabetic rats. Methods: In order to test anti-ulcer activity of NaHS against indomet...

In an attempt to minimize the gastric ulcerogenicity of 6-methoxyindan-1-acetic acid and 5,6-dimethoxyindan-1-acetic acid exhibiting high anti-inflammatory activity, we synthesized their esters, amides and nitrile derivatives. It was found that the anti-inflammatory activity of ethyl esters were almost equal to those of parent acids and phenylbutazone while other derivatives were less potent. T...

Gastric mucosal cells, particularly parietal and chief cells, are usually affected by exogenous, and endogenous stimuli-induced gastritis. The integrity of these cells and their alterations are involved in the pathogenesis of numerous gastric disorders. Omeprazole, a gastric acid secretion blocker, is commonly used for gastrointestinal diseases due to its antioxidative stress and anti-inflammat...

BACKGROUND Nonsteroidal anti-inflammatory drugs are widely used in Brazil in spite of the known risks associated with their use, but investigation of their side effects conducted in this country has been far from sufficient. This study investigates the use of NSAIDs among patients undergoing upper endoscopy in the Hospital das Clínicas of the Federal University of Minas Gerais and the associati...

BACKGROUND ML 3000 ([2,2-dimethyl-6-(4-chlorophenyl)-7-phenyl-2,3-dihydro-1H-pyrrolizine-5-yl]-acetic acid) is an inhibitor of both cyclooxygenase and 5-lipoxygenase in vitro, and shows promise as a novel non-steroidal anti-inflammatory drug (NSAID). Unlike conventional NSAIDs which are associated with gastric ulcerogenic effects, ML 3000 causes little or no damage to the gastric mucosa, even t...

Nonsteroidal anti-inflammatory drugs elevate gastric acid secretion, possibly contributing to their ability to interfere with gastric ulcer healing. Inhibitors of cyclooxygenase-2 have been shown to delay experimental gastric ulcer healing. In the present study, we tested the hypothesis that cyclooxygenase-2-derived prostaglandins modulate gastric acid secretion. Studies were performed in norma...

− In this study we investigated the effects of Magnolia Bark (MB) extract and its constituents, such as honokiol and magnolol, on gastritis in rats and the growth of human gastric cancer cells. The MB extract, honokiol, and magnolol showed the acid-neutralizing capacities, the antioxidant activities, and the inhibitory effect on the growth of Helicobacter pylori (H. pylori.) at the dose of 50 μ...
