Herbal medicines appeared promising in prevention of many diseases. This study was conducted to investigate the gastroprotective effect of Curcuma xanthorrhiza leaf in the rats induced gastric ulcer by ethanol. Normal and ulcer control received carboxymethycellulose (5 mL/kg) orally, positive control was administered with 20 mg/kg omeprazole (reference drug) and 2 groups were received 250 mg/kg...

Morinda citrifolia is a member of the Rubiaceae. It is a Shrub or compacted to twisted small tree up to 8 m high with square stems and large stipules between nodes and petioles. Leaves are opposite, petiolate, glossy, mostly ovate, 15-35 cm long. Flowers white, up to 15 mm long, with a tubular corolla and 5 spreading lobes, the flowers borne on a globose syncarp. Fruit a large fleshy syncarp up...

BACKGROUND/AIMS Aging gastric mucosa is known to have decreased mucosal defenses and increased susceptibility to injury by nonsteroidal anti-inflammatory drugs. Depending on the type of nonsteroidal anti-inflammatory drug (NSAID), the underlying mechanisms and the extent of damage to the stomach or intestine may differ. This study was performed to evaluate the acute gastric damage caused by dif...

This study examined the effects of indomethacin and rofecoxib on normal and Helicobacter pylori (H. pylori)-infected gastric mucosa of Mongolian (M.) gerbils. M. gerbils (6-wk-old) were orally administered H. pylori (ATCC43504, 2 x 10(8) CFU/ml) after fasting for 24 hours. Beginning 3 mo after inoculation, indomethacin (2 mg/kg, s.c) or rofecoxib (10 mg/kg, p.o.) was administered once daily for...

In this study, histopathological and immunohistochemical evaluations were made on the damage to gastric tissue in peptic ulcer model induced by indomethacin, it was investigated whether plants Hypericum perforatum Rosa spinosissima have a therapeutic effect. order create an model, 25mg/kg indomethacin administered orally rats other groups, except sham control group, 2 doses, 24 hours apart. tre...

A group of novel nitric oxide (NO) donating chalcone derivatives was prepared by binding various amino chalcones with different NO donating moieties including; nitrate ester, oximes and furoxans. Most of the prepared compounds showed significant anti-inflammatory activity using carrageenan-induced rat paw edema method compared with indomethacin. The prepared compounds exhibited more protection ...

experimental acute gastric ulcer is produced by the intraperitoneal injection of a single dose of indomethacin. acetazoleamide, a potent carbonic anhydrase inhibitor, has significantly prevented the occurrence of these ulcers. its probable mechanism is discussed.

To elucidate the role of cyclooxygenase (COX)-2 in ulcer healing, we compared the effects of NS-398 (COX-2-selective inhibitor) and indomethacin (nonselective COX inhibitor) on the healing of acetic acid-induced gastric ulcers in rats. Prostaglandin E2 (PGE2) production was elevated in ulcerated tissue, but remained unaffected in intact tissue. COX-2 mRNA was only detected in the ulcerated tiss...

In search of novel gastroprotective agents, mangiferin, a naturally occurring glucosylxanthone from Mangifera indica L. (Anacardiaceae), was evaluated in mice on gastric injury induced by ethanol and indomethacin. The effects of mangiferin on gastric mucosal damage were assessed by determination of changes in mean gastric lesion area or ulcer score in mice and on gastric secretory volume and to...
