The present study was designed to investigate the gastroprotective, analgesic, and antipyretic effects of curcumin (Cur), the major constituent of turmeric. Acetylsalicylic acid (ASA) was used in this study as a standard drug for comparison. The analgesic activity was measured using the Hot-Plate Test. The antipyretic and antiulcer effects were assessed using yeast-induced pyrexia and gastric u...

Aronia melanocarpa (Michx.) Ell. belongs to the Rosaceae family. The purpose of this study is to explore the gastroprotective effect of the Aronia melanocarpa hydro-alcoholic extract (AMHAE) against ethanol-induced gastric ulcer in a rat model. Different concentrations (50, 100, and 200 mg/kg) of AMHAE, or 30 mg/kg of omeprazole, significantly inhibited the gastric injury formation. The ethanol...

Objective: To evaluate the gastroprotective effects of β 3 -adrenoceptor agonists CGP 12177A and SR 58611A, on water immersion plus restraint stress (WIRS)-induced gastric ulceration in rats. Material and Methods: Drugs were administered (5, 10 and 15 mg/kg, p.o. ) 30 min prior to the ulcerogenic procedure. Ulcer index and the score for intensity of intraluminal bleeding were determined. Gastri...

Gastric hyperacidity and gastroduodenal ulcer is a very common global problem today. It is now generally agreed that gastric lesions develop when the delicate balance between some gastroprotective and aggressive factors are lost. The objective of present study is to evaluate the effects of omeprazole on healing of non-steroidal antiinflammatory drug (aspirin) induced peptic ulceration in adult ...

Adherence of neutrophils to the vascular endothelium is an early and critical event in the pathogenesis of gastric injury induced by NSAIDs. Pretreatment with glucocorticoids has been shown to prevent NSAID-induced neutrophil adherence and, in turn, to protect the stomach from injury. Some of the anti-inflammatory effects of glucocorticoids, including inhibition of neutrophil adherence, are med...

Gastric ulcers are a worldwide health problem and their poor healing is one of the most important causes for their recurrence. We have previously reported the remarkable gastroprotective and anti-Helicobacter pylori activities of the methanolic extract (CpMet) of Cyrtocarpa procera bark. This work investigates, in a murine model, the CpMet gastroprotective mechanism and establishes its preclini...

OBJECTIVES Several lines of evidence indicate that neuropeptides exhibit protective properties against gastroduodenal ulcers. Neurotensin, a gut-brain neuropeptide, is implicated in a number of physiological processes in the central nervous system and peripheral tissues including gastrointestinal tract. In the present study, we aimed to investigate the gastroprotective potential of either perip...

Increasing number of evidence suggest that gastric mucosal protection can be induced also centrally. Several neuropeptides, such as TRH, amylin, adrenomedullin, enkephalin, beta-endorphin, nociceptin, nocistatin, ghrelin or orexin given centrally induce gastroprotection and the dorsal vagal complex and vagal nerve may play prominent role in this centrally initiated effect. Since also cannabinoi...

In the present study a hydroalcoholic extract of Syzygium cumini seeds have been investigated for its antioxidant activity in aspirin induced peptic ulcer in rats with the aim of exploring possible correlation between its antioxidant and antiulcer activities. Oxygen free radicals are considered to be important factors in the pathogenesis of peptic ulcer. The level of lipid peroxide was elevated...

A rhamnogalacturonan (RGal) isolated from Acmella oleracea (L.) R.K. Jansen administered by oral route showed gastroprotective activity against acute lesions induced by ethanol. In this study, we investigated the gastric ulcer healing effect of RGal and its mechanisms of action. Intraperitoneal treatment of animals with RGal protected the gastric mucosa against acute lesions induced by ethanol,...
