A mixture of vitamin B,, and normal gastric juice, instilled through an intestinal tube into the ileum, produces haematological remission in patients with tapeworm pernicious anaemia. When a similar mixture is administered by mouth, this effect fails to occur. This observation constitutes evidence in favour of the view that Diphyllobothrium latum, attached to the proximal portion (jejunum) of the intestine, absorbs the vitamin B,, contained in the food, thus preventing vitamin bound to the intrinsic factor of the gastric juice from reaching the receptors in the distal portions of the small intestine of the host. In genuine pernicious anaemia, remission results from the administration of vitamin B,,+gastric juice both by mouth and into the ileum.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
