Изучить в хронических опытах на крысах патоморфологические изменения в почках при инфекции мочевых путей. МАТЕРИАЛЫ И МЕТОДЫ. В эксперименте на крысах применен способ моделирования пиелонефрита, который воспроизведен введением суточной культуры кишечной палочки в количестве 200-500 млн микробных тел в просвет мочеточника, с последующей его перевязкой. РЕЗУЛЬТАТЫ. Установлено, что во все сроки наблюдения после воспроизведения в эксперименте патологических процессов морфологические изменения развиваются в основном в канальцах и интерстиции почек, инфильтративно-продуктивное воспаление с поражением клубочков и фиброзом различной степени выраженности. ЗАКЛЮЧЕНИЕ. Выявлен определенный параллелизм между типом моделирования патологического процесса и интенсивностью развития морфологических изменений в почках. Микроскопические изменения могут служить критериями вовлечения в патологический процесс паренхимы почек и важным прогностическим признаком.</p></abstract><trans-abstract xml:lang="en"><p>AIM OF RESEARCH: To study in chronic experiments on rats pathomorphological changes in kidney in urinary tract infection. MATERIALS AND METHODS: In experimental on rats used pyelonephritis modeling method, which reproduced by introducing daily culture E. Coli in the amount 200-500 mln. microbic bodies into ureter lumen, with its subsequent ligation. RESULTS: It is established that in all observation time after simulated pathological processes considerable morphological changes mainly occurred in the kidneys tubules and interstitial. The changes presented with signs of infiltrative-productive inflammation as well as fibrosis of different levels of intensity. CONCLUSION: A definite correlation between the type of simulated pathological process and the intensity of morphological changes in the kidneys was revealed. Microscopic changes can serve as criteria of kidneys parenchyma involvement in the pathological process as well as to become an important prognostic sign.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>эксперимент</kwd><kwd>инфекция</kwd><kwd>пузырно-мочеточниковый рефлюкс</kwd><kwd>крысы</kwd></kwd-group><kwd-group xml:lang="en"><kwd>experiment</kwd><kwd>infection</kwd><kwd>vesicoureteric reflux</kwd><kwd>rats</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Baek M., Paick S.H., Jeong S.J., Hong S.K., et al.
