The dynamics of intestinal mucosal mast cells and the major mucosal mast cell protease were followed during the course of laboratory infections of mice with Hymenolepis diminuta and H. microstoma. The effects of the drug cyclosporin A (CsA), which is both immunosuppressive and selectively
Comparative studies were made of two populations of Sprague-Dawley rats infected with Hymenolepis diminuta. The time course of infection, the development of mucosal mastocytosis and the levels of rat mucosal mast cell (MMC) protease (RMCP II) in serum and in jejunal mucosal tissues were monitored at
N-acetyltransferase activities with p-aminobenzoic acid and 2-aminofluorene were determined in Hymenolepis nana, a cestode found in the intestine of the Sprague-Dawley rats. The N-acetyltransferase activity was determined using an acetyl CoA recycling assay and high pressure liquid chromatography.
It is well known that the destrobilation and later expulsion are characteristics of multiple Hymenolepis diminuta infections in rats. This process is suggested to be mediated by a variety of host cellular responses. It has also been suggested that immunoglobulin (Ig) E may have a beneficial role for
Infection with helminth parasites triggers strong and stereotypic immune responses in humans and mice, which can protect against specific experimentally-induced autoimmune diseases. We have shown that infection with the rat tapeworm, Hymenolepis diminuta, confers a protective effect on FCA-induced
