title: The gastroprotective effect of Memora nodosa roots against experimental gastric ulcer in mice.
abstract: Memora nodosa is popularly known as "caroba" and widely found in the Cerrado regions of Brazil. In traditional medicine, the leaves and stems are used for the healing of external ulcer and the roots for abdominal pain. This study investigated the effect of ethanolic roots extract of Memora nodosa (EMN) on the gastric mucosa of mice. In the indomethacin induced gastric ulcer model, the treatments of the animals with EMN at doses of 100, 300 and 1000 mg/kg, p.o., markedly reduced the index of lesions. In the gastric ulcer models induced by ethanol and cold restraint-stress the previous treatment with EMN at dose of 300 mg/kg showed 69% and 43% of protection, respectively. Seven days after food-restriction, the animals treated with EMN (300 mg/kg p.o.) showed reduction in the index of lesion by 65% as compared to control group. The intraduodenal administration of EMN (300 mg/kg) did not alter the gastric acid secretion parameters. The treatment with EMN (300 mg/kg p.o.) did not alter glutathione levels (GSH), but showed an increase of adhered gastric mucus as compared to the control group with lesion. These results showed that EMN has gastroprotective activity probably due with an increase of adhered gastric mucus.
