Патофизиологические механизмы бактериального эндотоксикоза при странгуляционной кишечной непроходимости

Патофизиологические механизмы бактериального эндотоксикоза при странгуляционной кишечной непроходимости

Abstract

В эксперименте на 12 беспородных собаках и 20 крысах породы Вистар исследованы патофизиологические механизмы развития бактериального эндотоксикоза при странгуляционной. кишечной непроходимости методом сцинтиграфии с бактериальным радиопрепаратом (меченными технецием-99m бактериями D. coli), приготовленным по оригинальной методике. Количественную оценку процессов бактериальной транслокации проводили путем расчета индекса транслокации (ИТ). Результаты исследования продемонстрировали, что формирование бактериального эндотоксикоза при странгуляционной кишечной непроходимости у собак и крыс происходило за счет транслокации бактерий E. coli из просвета ущемленного отдела тонкой кишки в брюшную полость с последующим развитием системной бактериемии за счет перитонеальной резорбции. Таким образом, патофизиологические механизмы и пути развития бактериемии в условиях странгуляционной кишечной непроходимости у мелких (грызуны) и крупных (млекопитающие) лабораторных животных однотипны что позволяет считать эти закономерности универсальными.

We analyzed pathophysiological mechanisms of bacterial endotoxicosis at the strangulated intestinal obstruction. in 12 pedigreeless dogs and 20 Wistar rats by the method of scintigraphy with bacterial radiopreparation (E. Coli bacteria tagged by technecium-99m) made by original methodology. Quantitative assessment of processes of bacterial translocation was performed by the calculation of translocation index (TI). The results of the research showed that formation of bacterial endotoxicosis at the strangulated intestinal obstruction, in dogs and rats arose from the translocation of E. Coli bacteria from lumen of strangulated section of small intestine to the abdominal cavity with further development of system bacteriemia due to peritoneal resorption. So pathophysiological mechanisms and ways of development of bacteriemia in conditions of strangulated intestinal obstruction in small (rodents) and large (mammals) laboratory animals are similar that allows to consider these regularities universal.
