Villi were examined by both light and scanning electron microscopy.Results: Acetylsalicylic acid induced severe lesions in duodenal mucosa of rabbits, including erosions, epitheliumdisorganization, and cell vacuolization, increasing as well the amount of mononuclear and caliciform cells. Damage wasmuch more severe in animals treated for 28 days. In groups receiving Plantago ovata husk, a significant attenuation ofacetylsalicylic acid-induced lesions was already observed in group treated for 14 days, becoming more evident in thosetreated for 28 days, all of them with duodenal cytoarchitecture normal and similar to control animals.Conclusions: These findings suggest that Plantago ovata husk may protect intestinal mucosa probably by limitingacetylsalicylic acid penetration into epithelial cells, although further studies are needed to confirm the same effect inother experimental models of induced mucosal damage and to elucidate the mechanisms of fiber protection.
