Оценить функциональное состояние глутатионовой системы у женщин бурятского этноса с инсомнией в климактерическом периоде.   Методы. В исследовании участвовали 94 женщины в возрасте от 45 до 60 лет в перименопаузе (n = 44) и постменопаузе (n = 50) с инсомническими нарушениями (основные группы) и без таковых (контроль). Уровень восстановленного (GSH) и окисленного (GSSG) глутатиона определяли в лизате эритроцитов, концентрацию глутатион-S-трансферазы π и активность глутатионредуктазы – в сыворотке крови.   Результаты. У женщин с инсомнией в обеих фазах климактерия установлено повышение уровня GSH (p &lt; 0.05) с одновременным увеличением соотношения GSH/GSSG (p &lt; 0,05) без каких-либо различий в параметрах глутатион-зависимых ферментов. Сравнительный анализ основных групп показал увеличение соотношения GSH/GSSG (p &lt; 0,05) в постменопаузальном периоде по сравнению с перименопаузой.   Заключение. Учитывая активацию глутатионового звена у женщин бурятского этноса с инсомнией в менопаузе, назначение препаратов глутатионового ряда для коррекции у них свободнорадикального гомеостаза не может быть рекомендовано.</p></abstract><trans-abstract xml:lang="en"><p>   The aim of the study was to assess the functional state of glutathione system in menopausal women of the Buryat ethnic group with insomnia.   Methods. The study involved 94 women aged 45 to 60 years who were divided into perimenopause (n = 44) and postmenopause (n = 50) groups. In each period, a control group and an insomniac group were identified. The reduced (GSH) and oxidized (GSSG) glutathione levels in erythrocyte lysate, the glutathione-S-transferase π concentration and glutathione reductase activity in blood serum were determined.   Results. An increase of the GSH level (p &lt; 0.05) and GSH/GSSG ratio (p &lt; 0.05) both in perimenopausal and postmenopausal women with insomnia were found as compared to controls. There were no differences in the glutathione-depends enzymes parameters. Comparative analysis of the main groups showed an increase GSH/GSSG ratio (p &lt; 0.05) in the postmenopausal period compared with perimenopause.   Conclusion. The study results demonstrate the glutathione link activation in Buryat menopausal women with insomnia. In this regard, the appointment of glutathione preparations for the correction of free radical homeostasis in these groups of women cannot be recommended.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>глутатион</kwd><kwd>глутатионредуктаза</kwd><kwd>глутатион-S-трансфераза</kwd><kwd>инсомния</kwd><kwd>менопауза</kwd><kwd>этнос</kwd></kwd-group><kwd-group xml:lang="en"><kwd>glutathione</kwd><kwd>glutathione reductase</kwd><kwd>glutathione-S-transferase</kwd><kwd>insomnia</kwd><kwd>menopause</kwd><kwd>ethnicity</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Данная работа выполнена в рамках НИР ФГБНУ НЦ ПЗСРЧ с использованием оборудования ЦКП «Центр разработки прогрессивных персонализированных технологий здоровья» ФГБНУ НЦ ПЗСРЧ (Иркутск).
