Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Barks of Ximenia americana are used by the population to treat gastrointestinal inflammatory disorders. Indomethacin is a non-selective non-steroidal anti-inflammatory drug that induces marked gastrointestinal damage. AIMS OF THE STUDIES To evaluate the gastroprotective activity of total polysaccharides contained in the extract (TPL-Xa) or tea (Tea-Xa) of Ximenia americana barks in the mice gastric damage induced by indomethacin. MATERIALS AND METHODS TPL-Xa was obtained by a combination of NaOH extraction and ethanol precipitation. Tea-Xa was prepared in distilled water boiled during 5 min. Animals received p.o. 0.9% NaCl (saline - control group), TPL-Xa (1-90 mg/kg) or Tea-Xa 1 h before gastritis induction by indomethacin (20 mg/kg). Mice were sacrificed 7 h after gastritis induction and analyzed for the following parameters: stomach lesions measurement; histological evaluation; myeloperoxidase (MPO) activity; nitrate/nitrite and cytokine levels; leukocyte adhesion and rolling by intravital microscopy. RESULTS TPL-Xa reduced macroscopic and microscopic damage, MPO activity (59%), leukocyte rolling (86%) and adhesion (84%), nitrite/nitrate ratio (100%) and IL-8 (69%), but increased IL-4 (50%). Tea-Xa (12.8 yield; 39.3% carbohydrate, including 25.8% uronic acid; 4% protein) reduced macroscopic damage (62%) and MPO activity (50%). CONCLUSION TPL and Tea of Ximenia americana barks ameliorate the gastric injury induced by indomethacin in mice, an effect that was dependent on the reduction of neutrophil infiltration.

Abstract
Here, we have evaluated the protective effect of the NO donor cis-[Ru(bpy)2(SO3)NO](PF6) (FOR0810) in experimental models of gastric damage induced by naproxen or ethanol in mice, and the involvement of soluble guanylate cyclase (sGC) and ATP-sensitive K(+) channels (KATP) in these events. Swiss mice were pre-treated with saline, ODQ (a soluble guanylate cyclase inhibitor; 10 mg kg(-1)) or glibenclamide (a KATP channels blocker; 10 mg kg(-1)). After either 30 min or 1 h, FOR0810 (3 mg kg(-1)) was administered. At the end of 30 min, the animals received naproxen (300 mg kg(-1)) by gavage. After 6 h, the animals were sacrificed and gastric damage, myeloperoxidase (MPO) activity, and TNF-α and IL-1β gastric concentrations were evaluated. In addition, the effects of FOR0810 on naproxen-induced mesenteric leukocyte adherence were determined by intravital microscopy. Other groups, were pre-treated with saline, ODQ or glibenclamide. After either 30 min or 1 h, FOR0810 was administered. At the end of 30 min, the animals received 50% ethanol by gavage. After 1 h, the animals were sacrificed, and gastric damage, gastric reduced glutathione (GSH) concentration and malondialdehyde (MDA) levels were determined. In naproxen-induced gastric damage, FOR0810 prevented gastric injury, decreased gastric MPO activity and leukocyte adherence, associated with a decrease in TNFα and IL-1β gastric concentrations. FOR0810 also prevented ethanol-induced gastric damage by increase in GSH levels and decrease in MDA levels. ODQ and glibenclamide completely reversed FOR0810's ability to prevent gastric damage by either naproxen or ethanol. We infer that FOR0810 prevented gastric damage through the activation of both sGC and KATP channels, which triggered a decrease in both free radical and cytokine production via the blocking of neutrophil adhesion and infiltration.
