Healing-promoting action of rhinax with dual action on chronic gastric and duodenal ulcers induced by acetic acid in rats.

ABSTRACT

Healing promoting actions of Rhinax, a multiconstituent herbal preparation, was investigated in chronic gastric and duodenal ulcer models induced by acetic acid in rats and the effects were compared with those of famotidine by gross of histological evaluation. Rhinax markedly promoted the well balanced healing of gastric ulcer at oral does of 25-100 mg/kg x 2 /day, as evidenced by the reduction of ulcer, regeneration of mucosa and proliferation of connecitve tissue. Rhinax caused an increase in gastric mucosa secretion in all the regenerated mucosa around the gastric ulcers. Famotidine failed to promote the healing of gastric ulcers at 100 mg/kg x 2/ day p.o. Rhinax also significantly accelerated the healing of acetic acid -induced duodenal ulcers as well famotidine. These results indicate that Rhinax is characterised by a potent promoting action on the healing of chronic ulcers, suggesting that the increase in gastric mucus secretion might be associated with the antiulcer action of Rhinax in rats.
