| Abstract: | The current study aims to determine the healing activity of water soluble polysaccharide-rich fraction of a wild mushroom, Termitomyces eurhizus (TEps) against the indomethacin induced gastric ulceration in mice model. Gastric tissue histology, myeloperoxidase (MPO) activity, cyclooxygenases (COX) 1 and 2 expression, prostaglandin E2 (PGE2) synthesis, and modulation of pro/anti inflammatory cytokines expression were studied for this purpose. Histological study shows that TEps (20 mg/kg) effectively healed the gastric ulceration. Based on biochemical results, the healing capacities of TEps could be attributed to reduction of MPO activity and protection of mucosal mucin content. Enhanced synthesis of PGE2 by modulation of COX-1 and COX-2 expression and a prominent shift of cytokines expression from pro (TNF-α, IL-1ß) to anti inflammatory (IL-10) side are also held responsible for ulcer healing. The preliminary study highlights the anti-ulcerogenic property of polysaccharide-rich fraction of Termitomyces eurhizus and opens an alternative cure for NSAID induced gastroduodenal diseases. |
