МАТЕРИАЛ И МЕТОДЫ. Самцы крыс Wistar на протяжении 3 недель получали в виде питья 1%-ный раствор этиленгликоля. В моче, собранной за сутки, определяли концентрацию оксалата, кальция и фосфора, а также активность маркерных ферментов лактатдегидрогензы (ЛДГ), γ-глютамилтрансферазы (ГГТ) и N-ацетил-β-D-глюкозаминидазы (НАГ). Гистохимически методом Косса на почечных срезах крыс определяли наличие кальций-позитивных отложений. РЕЗУЛЬТАТЫ. Ежедневное употребление крысами этиленгликоля сопровождалось развитием гипероксалурии, что обусловлено повышенным образованием в печени ионов оксалата и созданием оксалатного сверхнасыщения в канальцевой моче. В ходе экспериментов выяснилось, что ферментативная активность мочи на фоне этиленгликоля существенно увеличивалась. Активность НАГ выросла почти в 20 раз, ГГТ – в 3,7 раза. Активность ЛДГ, повышавшаяся к исходу первой недели в 7,5 раза, затем постепенно возвращалась к исходному уровню. Эти изменения свидетельствуют о повреждении мембран клеток канальцев, сопровождающимся цитолизом, а также о выраженном нарушении функции почечных канальцев. Морфологическое исследование срезов почек показало наличие многочисленных кальций-позитивных депозитов, локализованных в основном на поверхности почечного сосочка. ЗАКЛЮЧЕНИЕ. В результате экспериментов с длительным потреблением крысами этиленгликоля получены неопровержимые свидетельства развития кальций-оксалатного нефролитиаза. На это указывают развившиеся гипероксалурия, ферментурия и наличие кальций-позитивных включений на поверхности почечных сосочков. Перечисленные изменения являются признаками экспериментальной мочекаменной болезни у крыс.</p></abstract><trans-abstract xml:lang="en"><p>THE AIM of the investigation was to study kidney functions in rats under conditions of experimental oxalate nephrolithiasis. MATERIAL AND METHODS. Male Wistar rats were given drinking water with 1% solution of ethylene glycol during 3 weeks. The concentration of oxalate, calcium and phosphorus was determined in daily urine. Activity of marker enzymes lactate dehydrogenase (LDG), γ-glutamil transferase (GGT) and N-acetyl-β-D-glucosaminidase (NAG) was also determined. The presence of calcium-positive deposits on kidney slices was determined by the Koss histological method. RESULTS. Daily using ethylene glycol by rats was followed by the development of hyperoxaluria, which was due to increased formation of oxalate ions in the liver and appearance of oxalate supersaturation in tubule urine. In the experiments it was shown that enzymatic activation of urine against the background of ethylene glycol was substantially increased. Activity of NAG became 20 times higher, GGT – 3.7 times higher. LDG activity which had become 7.5 times higher by the end of the first week, then gradually returned to the initial level. These changes are evidence of injuries to the tubule cell membranes, followed by cytolysis and of pronounced impairment of the renal tubule function. Morphological investigation of kidney slices has detected numerous calcium-positive deposits localized mainly on the renal papilla surface. CONCLUSION. Experiments with continuous intake by rats of ethylene glycol have given an irrefutable proof of progression of calcium-oxalate nephrolithiasis. It points to the developed hyperoxaluria, fermenturia and the presence of calcium positive inclusions on the renal papilla surface. The above changes are signs of experimental urolithiasis in rats.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>этиленгликоль</kwd><kwd>нефролитиаз</kwd><kwd>функция почек</kwd></kwd-group><kwd-group xml:lang="en"><kwd>ethylene glycol</kwd><kwd>urolithiasis</kwd><kwd>kidney function</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">Тиктинский ОЛ, Александров ВП.
