We tested the hypothesis that recognized gastroprotective agents exert direct protection against ethanol-induced injury in isolated rat gastric mucosal cells in vitro. If protection exists, we also wanted to identify subcellular targets in the reversible and/or irreversible stages of cell injury. Ethanol-induced cell injury was quantified by measuring plasma membrane leakage (trypan blue exclus...

Gastric ulcer is the most digestive disease found in clinical practice. Punicalagin (PCG) found in pomegranate juice has antioxidant and tissue repair properties. Therefore, the aim of this study was to investigate punicalagin’s gastroprotective effect against ethanol-induce gastric injury. Four groups of rats; first group served as control, group 2: Treated with absolute ethanol (5 ml/kg, po),...

The present study was conducted to evaluate the antiulcerogenic effect and recognize the basic mechanism of action of Tabernaemontana divaricata (L.) R. Br. flowers. T. divaricata flower methanolic extract (TDFME) was screened for antiulcer activity versus aspirin and ethanol induced gastric ulcers at three doses--125, 250, and 500 mg/kg--orally using misoprostol as a standard. Besides histopat...

ment and spice, has been used therapeutically in traditional folk medicine for a wide range of ailments, including wound healing, urinary tract infection, and liver ailments. Although evidence suggests that a C. longa extract also has considerable gastroprotective and antiulcerogenic effects, its mechanism of action remains unclear. The genes encoding four histamine receptor subtypes (H1, H2, H...

Essential oil from Citrus aurantium and the monoterpene limonene are widely used flavoring agents that are found in some common food items. This specie is also used medicinally throughout the world to treat gastritis and gastric disorders. Therefore, biological assays were performed in vivo on essential oil of C. aurantium (OEC) and its majority compound limonene (LIM) to evaluate their effect ...

Simvastatin appeared to have additional benefits beyond their lipid lowering effects, which has led to interest in the use of this class of drugs outside the field of cardiovascular disease. Aim: This study aimed to investigate the possible gastroprotective effect of simvastatin against both indomethacin and cold restraint stress (CRS) induced gastric ulcers in rats and to study its effect on g...

The possibility of using different types of carrageenans (CRG) as matrixes for incorporating of echinochrome A (Ech) was investigated. Ech interacts with carrageenans and is incorporated into the macromolecular structure of the polysaccharide. The inclusion of Ech in carrageenan matrices decreased its oxidative degradation and improved its solubility. The changing in the charge and morphology o...

Manganese is a crucial element for health. In this study, the gastroprotective efficacy of Mn (II) complex (MDLA) against acidified ethanol (HCl/Ethanol)-induced gastric ulceration in rats was evaluated. The animals were distributed into 5 groups. Groups 1 and 2 received carboxymethylcellulose (CMC), group 3 was pretreated with omeprazole, and groups 4 and 5 were given 10 and 20 mg/kg of MDLA, ...

Byrsonima sericea leaves are extensively used in folk medicine in Brazil against gastric disorders. This study investigated the chemical constituents of B. sericea leaf ethanolic extract (BSLE) and its potential gastroprotective activity, with its possible mechanism of the action using ethanol to induce gastric mucosal damage in mice. The phytochemical analysis was carried out to identify the a...

Ghrelin, the endogenous ligand for GH secretagogue receptors, has been reported to influence acid gastric secretion and motility, but its potential gastroprotective effect is unknown. The aims of this study were 1) to examine the effects of central and peripheral administration of ghrelin on ethanol-induced gastric ulcers in conscious rats, and 2) to investigate the possible roles of nitric oxi...
