Разработка методики воспроизведения сосудистого спазма при нетравматических субарахноидальных кровоизлияниях in vivo на модели лабораторной белой крысы для оценки морфологических изменений сосудов головного мозга крысы в динамике. Сравнение спазмогенного эффекта венозной и артериальной аутокрови. Материалы и методы. Исследование было выполнено на 18 беспородных белых крысах массой 180-220 г. Всем животным осуществляли двукратное введение венозной и артериальной аутокрови в затылочную цистерну. Оценку неврологического статуса животных проводили ежедневно в течение всего эксперимента. Для морфологического исследования мозг забирали на 3-и, 4-е, 5-е, 6-е и 7-е сутки. Оценку микропрепаратов проводили на уровне верхней трети базилярной артерии. Микропрепараты окрашивали с применением специализированных гистохимических окрасок (по Грамм-Вейгерту, по Lie). Описание микропрепаратов проводили на светооптическом микроскопе Leica DM 1000 при увеличении 400-1000 раз, микрофотосъемку выполняли на цифровой камере Leica EC 3. Результаты. Были выявлены прямые качественные признаки сосудистого спазма в виде уменьшения диаметра просвета базилярной артерии, утолщения стенки сосуда, сморщивания внутренней эластической мембраны, гиперконтрактурных изменений гладкомышечных клеток. Сосудистый спазм выявлялся с 4-х суток от введения крови, с максимальной выраженностью на 5-е сутки и признаками разрешения на 6-7-е сутки. В головном мозге на уровне моста выявлены нарушения капиллярного кровотока, которые могут являться прямым признаком ишемии вследствие перенесенного спазма. Разницы между спазмогенным эффектом венозной и артериальной крови выявлено не было. Заключение. Предложенная модель введения аутокрови в затылочную цистерну крысы является адекватной для дальнейшего изучения сосудистого спазма, методов его профилактики и лечения при нетравматических субарахноидальных кровоизлияниях.</p></abstract><trans-abstract xml:lang="en"><p>Objective. To study the morphological changes in basilar artery and brain tissues during experimental nontraumatic subarachnoid haemorrhage using laboratory white rat as well as to compare the spasmogenic effect of venous and arterial autologous blood. Materials and methods. The study was performed using 18 laboratory white rat weighing 180-220 g. Venous and arterial autologous blood was injected in cistern magna twice. Neurological assessment of the animals was performed daily. Brain for morphological study was taken out at the 3rd, 4th, 5th, 6th and 7th day. Microscopy assessment was performed at the level of the upper third of the basilar artery using special histochemical stains (by Gram-Weigert, by Lie). Slide description was performed at the light microscope Leica DM 1000 with an increase of 400-1000 times, photomicrography was performed using digital camera Leica EC 3. Results. The direct qualitative evidences of cerebral vasospasm (reduction in luminal diameter of the basilar artery, thickening of the vessel wall, internal elastic membrane wrinkling, hypercontractive changes of smooth muscle cells) were identified. Vasospasm was detected on the 4th day, with maximum expression at day 5 and regression by 6-7 day. The direct indicators of brain ishemia in the form of capillary blood flow violations were identified at the pons level. There was no difference in spasmogenic effect comparing venous and arterial blood. Conclusion. The suggested model of autologous blood injection in cisterna magna of the rat is adequate and appropriate for further study of the cerebral vasospasm after nontraumatic subarachnoid haemorrhage as well as for investigation of the methods for cerebral vasospasm prevention and treatment.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>нетравматическое субарахноидальное кровоизлияние</kwd><kwd>сосудистый спазм</kwd><kwd>экспериментальная биологическая модель</kwd><kwd>белая крыса</kwd><kwd>nontraumatic subarachnoid haemorrhage</kwd><kwd>cerebral vasospasm</kwd><kwd>in vivo rat model</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">Krylov V.V., Gusev S.A., Gusev A.S., Titova G.P.
