[Effect of mold mycotoxins on the morphofunctional state of the small intestine of rats].

The entry of metabolites of the Aspergillus flavus mold into the gastrointestinal tract (GIT) with the food for one week causes inhibition of the activity of ATPase, cytochrome oxidase, and alkaline phosphatase; paranecrotic and morphologic changes in the tissue of the smooth muscles of the small intestine are encountered, which, evidently, underlies the disorders of intestinal digestion. The morphofunctional status of the small intestine is restored 5 days after the supply of mold metabolites into the GIT ceases.
