Выявлено, что при концентрациях реагентов выше 500 мкМ наблюдается лавинообразное накопление активных продуктов взаимодействия гемоглобина и реагентов системы «NaNO2+H2O2», предположительно, феррилгемоглобина, диоксида азота и пероксинитрита, что и инициирует окислительный взрыв в эритроцитах. Сопровождающее окислительный стресс закисление цитозоля до pH 6,5 активирует производство этих активных агентов в реакциях с внутриклеточным гемоглобином. Выдвинута гипотеза о наличии положительной обратной связи в механизме развития окислительного стресса в клетках с участием гемсодержащих белков.</p></abstract><trans-abstract xml:lang="en"><p>The conditions of development of impetuous oxidative stress in red blood cells (oxidative outburst) caused by red blood cell interaction with reagents of system «NaNO2+H2O2» with hemoglobin participation were studied. The avalanche accumulation of reactive species such as ferryhemoglobin, nitrogen dioxide, and peroxynitrite in the reaction of hemoglobin with reagent of the system «NaNO2+H2O2» was revealed at reagent concentration higher than 500 mМ. The intracellular acidosis down to pH 6,5 which accompanies the cellular oxidation stress activates the reactive species production in the hemoglobin reactions. Hypothesis of positive feedback presence in the mechanism of oxidative stress development with hemeprotein participation in cells was advanced.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>окислительный взрыв</kwd><kwd>активные формы азота</kwd><kwd>гемоглобин</kwd><kwd>эритроциты</kwd><kwd>oxidative stress</kwd><kwd>reactive nitrogen species</kwd><kwd>hemoglobin</kwd><kwd>red blood cell</kwd></kwd-group><kwd-group xml:lang="en"><kwd>окислительный взрыв</kwd><kwd>активные формы азота</kwd><kwd>гемоглобин</kwd><kwd>эритроциты</kwd><kwd>oxidative stress</kwd><kwd>reactive nitrogen species</kwd><kwd>hemoglobin</kwd><kwd>red blood cell</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">Суханова Л.Я., Каменская В.В.
