Abstract:
AIM To investigate the protective effects of three flavonoids quercetin,rutoside and flavone on the intestinal mucosal injury induced by burn in mice. METHOD The change of injury index of small intestine was assayed and the content of protein and DNA were measured. DTNB method were adopted to measure the GSH content in the intestinal mucosa. The level of DNA damaged were determined by measuring the fluorescence. RESULTS The condition of injury of intestinal mucosa were improved in varying degrees after these favonoids were given introgastrically for 3 days. The injury index of intestinal mucosa decreased and the content of protein,DNA and GSH increased. The degrees of DNA damage were reduced also.Quercetin was the most effective one among these three flavonoids. CONCLUSION The flavonoids of quercetin, rutoside and flavone have obvious protective effects on burn induced intestinal mucosal injury, and the mechanism may be related to its antioxydation function.
