    AbstractSennosides and related compounds are presumed to be severe cell poisons after prolonged ingestion. Some histological and ultrastructural studies in animals and man with such laxative misuse have revealed myenteric plexus and colonic epithelium injuries; but others have failed to point out identical data. In a first histological and ultrastructural study in mouse, we were unable to find any intestinal mucosa injury after long-term sennoside ingestion. In a second long-term experiment, we compared the effects of sennosides and 1,8-dihydroxyanthraquinone (synthetic anthracene derivative) on the mouse jejunum and colon. Electron microscopic observations showed nervous myenteric plexus abnormalities only in 1,8-dihydroxyanthraquinone-treated animals. These results suggest that sennosides have a good intestinal mucosa tolerance as opposed to aglycosidic-related compounds.
