Effects of the administration of aqueous extract of de Sedum dendroideum on the histopathology of erosive induced gastritis by means of indomethacin in rats.

OBJECTIVE

To evaluate the effects of acute administration of Sedum dendroideum on the gastric histopathology of rats after the administration of indomethacin.

METHODS

Twenty four Wistar rats were randomized into three groups, submitted to feeding privation for 24 hours prior to the oral administration of 50 mg/Kg of indomethacin and during the experimental period of six hours. The control group (C) was giving distilled water, the extract group (E) was treated with the extract of Sedum dendroideum and the group Omeoprazole (O) received 20 mg/Kg of omeoprazole. All the treatments were carried out thirty minutes prior to the administration of indomethacin. After six hour, the stomach of the animals was extirpated for histopathological analysis, which took into account the presence of erosive gastritis, hyperemia and sub mucosa edema.

RESULTS

In group C, eight out of eight animals presented that type of lesion, in group E, this number was the same and in group O, three out of the eight rats presented erosive gastritis.

CONCLUSIONS

Sedum dendroideum extract did not produce reduction in the erosive gastritis process. As expected, the treatment with omeoprazole produced a major reduction, when compared with the control group.
