Экспериментальных животных делили на 4 группы: 1  –получала оротовую кислоту (ОА –Orotic acid, Калия оротат, ОАО АВВА РУС, Россия) в исходной форме (оксо-таутомер), 2-я – получала гидрокси-таутомер ОА после механомодификации в течение 1 часа, 3-я –получала дигидрокси-таутомер ОА после механомодификации в течение 6 часов.На гистологических препаратах печени оценивали площадь гепатоцитов; диаметр и площадь центральной вены, междольковой вены и артерии, желчного протока; рассчитывали коэффициент Визотто.</p></sec><sec><title>Результаты</title><p>Результаты. Морфометрические  данные  анализа  микрососудистого  кровеносного  русла  печени при метионин-обусловленной гипергомоцистеинемии свидетельствуют об общем увеличении диаметра и площади, изменения затрагивают как системы притока, так и оттока крови на органном уровне. Введение ОА оказывает нормализующий эффект на сосудистое русло печени, однако результат от воздействия неодинаков: наиболее выраженным действием обладает гидрокси-таутомерная форма препарата, что объясняется  изменением  дисперсности  препарата  (без  изменения  кристаллической  решетки),  увеличением скорости  растворения в  воде  и  водных  растворах,  повышением  числа функционально  активных групп  в гетероцикле гидрокси-формы  ОА. Таким  образом,  наибольшую  эффективность  в  отношении  гипергомо-цистеинемической  вазодилятации  микрососудов  кровеносного  русла  печени  проявляет  гидрокси-таутомер  оротовой  кислоты,  что  предполагает  целесообразность  дальнейшего  ее  изучения  в  условиях клинической апробации.</p></sec></abstract><trans-abstract xml:lang="en"><p>The aim of  the  study  was  to  analyze  the  microvasculation  of  the  liver  in  administration  of  tautomeric forms of orotic acid for a methionine-induced liver pathology to assess the efficacy of the modified drugs and the potentialof their clinical use.</p><sec><title>Material and  methods</title><p>Material and  methods. The  study  included  30  white  outbred  rats,  that  were  simulated  methionine induced hyperhomocysteinemia by the administration of methionine, dosage 0.15 g/100 g of the body we ight, via food  during  4  weeks.  Animals  with  hyperhomocysteinemia  were  divided  into  4  groups:  animals  of  group  1  received orotic acid (OA) in the initial form (oxo-tautomer), animals of group 2 received hydroxy–tautomer OA after mechanomodification for 1 hour, animals of group 3 received dihydroxy-tautomer OA after mechanomodification for 6 hours. Histological preparations of the liver were used to evaluate the area of hepatocytes; diameters and areas of the central vein, the interlobular vein and artery, the bile duct, and the Visotto coefficient were calculated.</p></sec><sec><title>Results</title><p>Results. Morphometric  data  of  the  hepatic  microvascular  bloodstream  with  simulated  hyperhomocysteinemia evidenced a general increase in the diameter and area of blood vessels, changes affected the system of blood inflow and outflow at the organ level. Administration of OA had a normalizing effect on the liver bloodflow, but the effects were different: the most pronounced effect was detected in administration of the hydroxy-form of the preparation, this can be explained by a modificationin the dispersion of the preparation (without changing the crystal lattice), an increase in the rate of dissolution in water and aqueous solutions, an increasein the number of functionally active groups in the heterocycle of the hydroxy-form of OA. Thus, the hydroxy-tautomer of orotic acid had the greatest efficacy relating to vasodilation of microvessels of the liver bloodstream in hyperhomocysteinemia; the fact suggesting feasibility of its further study in the clinical environment.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>гипергомоцистеинемия</kwd><kwd>печень</kwd><kwd>кровеносное микрососудистое русло</kwd><kwd>орото-вая кислота</kwd><kwd>таутомерные формы оротовой кислоты</kwd><kwd>механомодифицированные препараты</kwd></kwd-group><kwd-group xml:lang="en"><kwd>hyperhomocysteinemia</kwd><kwd>liver</kwd><kwd>bloodflow</kwd><kwd>orotic acid</kwd><kwd>tautomeric forms of orotic acid</kwd><kwd>mechanomodified preparations</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">Болдырев В.В., Авакумов Е.Г.
