Нефропротекторный эффект блокады АТ1 рецепторов после острого нарушения уродинамики

Нефропротекторный эффект блокады АТ1 рецепторов после острого нарушения уродинамики

Abstract

THE AIM of the investigation is concrete definition of morphogenetic mechanisms of realization of nephroprotective effect of AT1receptor blockade in rats after degradation of urodynamics which was produced in the model of acute obstruction of the ureter. MATERIAL AND METHODS. The first group (n=30) included animals without pharmacological correction. Rats of the second group (n=30) were given Lozartan (10 mg/kg a day) during 2 weeks after restoration of urodynamics. The morphological state of the kidney was investigated in 7, 14 and 30 days using quantitative criteria. RESULTS. In 7 days in the second group of animals there was optimization of the glomerular and peritubular blood flow with the decreased degree of alteration of the tubules of the cortical and external medullary substance by 26.41% and 48.51% respectively. The specific volume (SV) of infiltrates in the cortex external and internal medulla of the kidney with AT1 receptor blockade was respectively 36.57%, 40.34% (p

ЦЕЛЬЮ ИССЛЕДОВАНИЯ является конкретизация морфогенетических механизмов реализации нефропротекторного эффекта блокады АТ1 рецепторов у крыс после нарушения уродинамики, которое воспроизводили в модели острой обструкции мочеточника. МАТЕРИАЛЫ И МЕТОДЫ. В 1-ю группу вошли животные без фармакологической коррекции (n=30). Крысы 2-й группы (n=30) получали Лозартан (10 мг/кг в день) в течение 2 недель после восстановления уродинамики. Морфологическое состояние почки с использованием количественных критериев исследовали через 7, 14 и 30 суток. РЕЗУЛЬТАТЫ. Через 7 дней во 2-й группе отмечена оптимизация гломерулярного и перитубулярного кровотока при снижении степени альтерации канальцев коркового и наружного мозгового вещества соответственно на 26,41% и 48,51%. Удельный объем (УО) инфильтратов в коре, наружной и внутренней медулле почки КВ, НМ и ВМ органа при блокаде АТ1рецепторов был соответственно на 36,57%, 40,34% (p
