We investigated the mechanisms underlying the protective action of glucocorticoids against indomethacin-induced gastric lesions. One-week adrenalectomized rats with or without corticosterone replacement (4 mg/kg sc) were administered indomethacin (25 mg/kg sc), and gastric secretion (acid, pepsin, and mucus), motility, microvascular permeability, and blood glucose levels were examined. Indometh...

BACKGROUND AND AIM Lansoprazole, a benzimidazole derivative, is a widely-used proton-pump inhibitor. In addition, it has been reported to have an independent gastroprotective action. Since free radicals and antioxidant mechanisms appear to counter-act tissue-related injury, we studied the effect of lansoprazole on oxidative stress in acid-ethanol gastric injury. As this drug is metabolized in t...

Currently, proton pump inhibitors (PPIs), H2-histamine receptor blockers (H2-blockers), antacids, and anticholinergics are used to treat acid-dependent diseases of the gastrointestinal tract. PPIs considered most effective drugs for treatment However, in real clinical practice, interest remains use antacids diseases. This is due fact that not only adsorb hydrochloric acid gastric lumen (by buff...

BACKGROUND Synthetic steroids, such as 9α-bromobeclomethasonedipropionate, have shown gastroprotective activity. For example, the potent glucocorticoid steroid, beclomethasone dipropionate, has been used for treatment of bowel ulcerations. The purpose of the present study was to evaluate the effect of a synthetic steroid, (20S)-22-acetoxymethyl-6β-methoxy-3α,5-dihydro-3'H-cyclopropa[3α,5]-5α-pr...

Following the characterization of hypoglycemic, gastric emptying inhibitory, and gastroprotective principles and the structure elucidation of calendasaponins A, B, C, and D, two new ionone glucosides (officinosides A and B), and two sesquiterpene oligoglycosides (officinosides C and D), were isolated from the flowers of Egyptian Calendula officinalis. The structures of the officinosides were el...

OBJECTIVES Dalbergia sissoo Roxb. stem bark possesses anti-inflammatory, antipyretic, and antioxidant properties. This plant is used traditionally in the Indian system of medicine to treat emesis, ulcers, leucoderma, dysentery, stomach complaints, and skin disorders. This study was conducted to evaluate the antiulcer effects of D. sissoo stem bark methanol extract (DSME) against the diclofenac ...

BACKGROUND Nanostructured lipid carriers (NLCs), composed of solid and liquid lipids, and surfactants are potentially good colloidal drug carriers. Thymoquinone is the main bioactive compound of Nigella sativa. In this study, the preparation, gastroprotective effects, and pharmacokinetic (PK) properties of thymoquinone (TQ)-loaded NLCs (TQNLCs) were evaluated. METHOD TQNLCs were prepared usin...

The gastroprotective effect of the hexane extract of the leaves of Sesamum indicum (HESI) was investigated in twenty-eight male rabbits. Gastroprotective activity against necrotizing agent induced ulceration was studied. Gastric wall mucus was determined by standard methods. Anti-secretory activity was determined in twelve pyloric-ligated rabbits. Phytochemical and acute toxicity tests were per...

A renewed interest in using nature-originated medicines can be seen throughout the world due to their benefits when compared synthetic or semi-synthetic drugs aspect of increasing quality life human beings. Pogostemon heyneanus Benth is a prominent and well-known medicinal plant Asian countries that recommended with high value traditional practices, Ayurvedic treatments folkloric use. It also k...
