Dynamic Ileus

Today, the histological criteria for differential diagnosis of dynamic ileus due to peritonitis and mechanical obstruction of the intestine remain undeveloped. In this regard, the aim of the work was to establish the difference in morphological changes occurring in the intestinal wall during dynamic and mechanical ileus in the experiment. The experiment was conducted on 33 sexually mature Wistar rats. In 15 animals of the first group, mechanical ileus was modeled by ligation of the lumen of the small intestine at the middle of the distance between the duodenojejunal junction and the ileocecal angle. In 15 rats of the second group, a dynamic ileus model was formed in the form of peritonitis by introducing fecal suspension into the lumen of the abdominal cavity. The control group included 3 animals who underwent laparotomy without the formation of mechanical ileus and peritonitis. For histological examination, fragments of the intestinal wall were sampled 1 cm above the site of the obstruction with mechanical ileus and the portion of the small intestine with peritonitis. Statistical processing was performed in an Excel package using parametric statistics methods. It was stated that with mechanical ileus purulent inflammation develops in the intestine wall beginning from the mucous membrane spreading over wall thickness which can cause its destruction within 48 hours; with dynamical ileus purulent inflammation develops in the intestine wall, it captures particularly serous and muscle layers without causing violations of mucosa cover structure and without intestine wall destruction within 48 hours. Under experimental dynamic ileus, changes in the mucous membrane were reactive in nature and consisted of manifestations of compensatory-adaptive and regenerative processes in response to a violation of the trophism of various structures of the intestinal wall.

The elemental composition of amino acids is similar to that of the major structural components of the epithelial cells of the small intestine and other tissues. Therefore, their subcellular localization and concentration measurements are not possible by x-ray microanalysis. Radioactive isotope labeling: I131-tyrosine, Se75-methionine and S35-methionine have been successfully employed in numerous absorption and transport studies. The latter two have been utilized both in vitro and vivo, with similar results in the hamster and human small intestine. Non-radioactive Selenomethionine, since its absorption/transport behavior is assumed to be the same as that of Se75- methionine and S75-methionine could serve as a compound tracer for this amino acid.

Crystalline Nature

Trichinella spiralis induces a profound mastocytosis and eosinophilia in the small intestine of the infected mouse. Mouse mast cells (MC) store in their granules various combinations of at least five chymotryptic chymases [designated mouse MC protease (mMCP) 1 to 5], two tryptic proteases designated mMCP-6 and mMCP-7 and an exopeptidase, carboxypeptidase A (mMC-CPA). Using antipeptide, protease -specific antibodies to these MC granule proteases, immunohistochemistry was done to determine the distribution, number and protease phenotype of the MCs in the small intestine and spleen 10 to >60 days after Trichinella infection of BALB/c and C3H mice. TEM was performed to evaluate the granule morphology of the MCs between intestinal epithelial cells and in the lamina propria (mucosal MCs) and in the submucosa, muscle and serosa of the intestine (submucosal MCs).As noted in the table below, the number of submucosal MCs remained constant throughout the study. In contrast, on day 14, the number of MCs in the mucosa increased ~25 fold. Increased numbers of MCs were observed between epithelial cells in the mucosal crypts, in the lamina propria and to a lesser extent, between epithelial cells of the intestinal villi.
