Эксперименты проводились на крысах стока Wistar — конвенциональных и с SPF статусом. Исследовались динамика систолического артериального давления (САД), межисистольного интервала (МСИ) и компонентов спектра вариабельности сердечного ритма (ВСР) через 1, 2 и 8 недель после клипирования почечной артерии. Установлено, что конвенциональные и SPF животные различаются по исходным параметрам. У SPF крыс САД ниже, МСИ и ВСР больше, по сравнению с конвенциональными животными. У крыс с SPF статусом подъем САД через 8 недель после стенозирования почечной артерии был ниже, по сравнению с конвенциональными животными. Отмечены общие моменты в динамике вазоренальной гипертензии двух групп животных: увеличение маркеров активности симпатической нервной системы спектра ВСР в первые недели после клипирования почечной артерии, устойчивая вазоренальная гипертензия развивалась не у всех клипированных крыс, а также тенденция уменьшения длины МСИ при развитии устойчивой вазоренальной гипертензии. Кроме того, у крыс с SPF статусом наблюдалось существенное уменьшение ВСР через 8 недель после клипирования почечной артерии. В итоге, хотя вазоренальная гипертензия развивалась лучше в группе конвенциональных крыс, динамика вариабельности МСИ была более четко выражена у животных с SPF статусом, к тому же для выявления изменений компонентов спектра ВСР требовалось меньшее количество животных с SPF статусом, чем конвенциональных.</p></abstract><trans-abstract xml:lang="en"><p>The aim of this study was to investigate the effects of the quality of laboratory rats on the dynamics of vasorenal hypertension in model “2 kidneys, 1 clamp”. Experiments were conducted on rats strain Wistar - conventional and SPF status. The dynamics of systolic blood pressure (SBP), beat-to-beat interval (RR) and components of the spectrum of heart rate variability (HRV) were explored via 1, 2 and 8 weeks after renal artery clipping. It was found, that conventional and SPF animals differ in basic parameters. SPF rats have a SBP below, RR and HRV more, compared to conventional animals. Through 8 weeks after renal artery clipping in rats with SPF status rise SBP was lower, compared to conventional animals. Marked similarities in the dynamics of vasorenal hypertension for both groups of animals: increase sympathetic nervous system activity markers of spectrum HRV in the initial weeks after renal artery clipping, stable vasorenal hypertension did not develop in all clipped rats, and the tendency to decrease the length of RR in the development of stable vasorenal hypertension. In addition, there was a significant reduction in HRV through 8 weeks following renal artery clipping in SPF rats. As a result, although vasorenal hypertension developed better in the group of conventional rats, the dynamics of variability of RR was more pronounced in animals with SPF status, besides, fewer animals with SPF status were required to detect changes in the components of the HRV spectrum than conventional animals.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>конвенциональные животные</kwd><kwd>SPF статус</kwd><kwd>вазоренальная гипертензия</kwd><kwd>вариабельность сердечного ритма</kwd></kwd-group><kwd-group xml:lang="en"><kwd>conventional animals</kwd><kwd>SPF status</kwd><kwd>vasorenal hypertension</kwd><kwd>heart rate variability</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при поддержке гранта РНФ 14-15-00745-П.</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Каркищенко Н.Н.
