Innervation of mucosal immune cells in the gastrointestinal tract.

There is mounting evidence for interactions between the immune and peripheral nervous systems. Many regulatory molecules are candidate mediators for communication between inflammatory cells and nerves; however, the extent of targeting of neurotransmitters (and interleukins) as intersystem messengers has been somewhat overlooked. Lymphoid tissues are well supplied by nerves and the gastrointestinal lamina propria, which is populated by a variety of immune cell types, is densely innervated. One-half to two-thirds of mast cells are closely apposed to nerves in the intestinal mucosa, in both rodents and humans, and nerve stimulation has been reported to cause mast cell activation. Although less extensively studied, both eosinophils and plasma cells in the gastrointestinal mucosa are also positioned for interaction with nerves, and intra-epithelial leukocytes may be subject to diffusible neurally-derived mediators. Peyer's patches are relatively sparsely innervated but appear to express neuropeptide receptors in inflammatory conditions. Although the nerves in the mucosa have traditionally been thought of as a static component, recent experiments suggest that these may undergo extensive remodelling during nematode-induced inflammation. Such data suggest a dynamic interplay between the immune and nervous systems during inflammatory episodes in the gut, although considerable work is still needed to determine the importance of neuro-immune interactions in gastrointestinal homeostasis and inflammation.

Intestinal obstruction due to Taenia saginata infection: a case report.

Surgical complications of Taenia saginata infection, the bovine tapeworm which man acquires by eating undercooked beef, are mentioned in standard texts; however, none of these seem to give any specific reference. Reported here is one case of acute mechanical intestinal obstruction due to a bolus impaction of Taenia saginata at the level of the ileocaecal valve. The rarity of this clinical presentation as well as the probable mechanism of obstruction are discussed.

[The helminth fauna of the red fox (Vulpes vulpes LINNE, 1758) in Nordhessen and Ostwestfalen. 2. Nematodes].

Between November 1989 and June 1990 a total number of 397 foxes were examined for the presence of nematodes in the stomach and the small intestine and 403 foxes for the presence of Trichinella spiralis larvae. The animals came from the districts of Kassel, Arnsberg and Detmold. In 32.7% of the foxes infections with Toxocara canis were found, in 11.1% Toxascaris leonina, in 3.8% Ancylostoma caninum, in 3.5% Uncinaria stenocephala and in 2.3% Capillaria species. In most cases the number of nematodes per fox was low. Only Toxascaris leonina was frequently found with more than 20 specimen per animal. Trichinella spiralis larvae were not found in any of the foxes.
