   <abstract xml:lang="ru">
    <p>Изучено влияние воды с пониженным по отношению к природному содержанием дейтерия на организм различных поколений лабораторных крыс в физиологических условиях, в ходе которых установлено, что наиболее существенное и быстрое снижение равновесия D/H наблюдалось в плазме крови, на 36,2%, а также в лиофилизированных тканях почки (на 15,8%). Менее выраженное уменьшение дейтерия характерно для тканей печени (на 9,3%) и сердца (на 8,5%). Была зафиксирована стабилизация скорости реакций изотопного обмена в крови и тканях изученных органов крыс, начиная со второго поколения. При этом на фоне введения в пищевой рацион воды с содержанием дейтерия 40 ppm также отмечено изменение морфофункциональных показателей у лабораторных животных, связанных с процессами адаптации к субстрессовому воздействию изотопного D/H градиента. В исследовании показано, что модификация только питьевого режима не позволяет существенно изменить содержание дейтерия в тканях метаболически активных органов, в связи с параллельным поступлением дейтерия в составе пищевых веществ растительного и животного происхождения.</p>

    <p>The influence of deuterium depleted water on the body of different rat generations was investigated in physiological conditions. As a result of this study it was established that the most significant and rapid reduction in D/H equilibrium was observed in plasma (by 36.2%), and lyophilized kidney tissues (by 15.8%). Less pronounced deuterium decrease was characteristic of liver tissue (9.3%) and heart (8.5%). Stabilization of the isotopic exchange reaction rate was fixed in the blood and tissues of rats, starting from the second generation. At the same time when deuterium depleted water (40 ppm) was used in dietary intake, the change in morphological and functional parameters in laboratory animals associated with the processes of adaptation to the effects of substress isotopic D/H gradient was also noted. The study shows that modification of only drinking water intake regime can’t significantly change the deuterium content in tissues of metabolically active organs, because of the concurrent deuterium receipt in feed substances of plant and animal origin.</p>
