Дане дослідження виконано для вивчення індукованих фотоперіодом змін біомаркерів окиснювального стресу у щурів різного віку та різною фізіологічної реактивністі, що
оцінюється за різною стійкістю до гіпоксії. Дослідження проведено на 96 щурах-самцях лінії Вістар, розділених на 16 груп залежно від стійкості до гіпоксії (НР, низькорезистентні, ВР, високорезистентні) та віку (6 та 21 міс.). Дослідження проводилися в чотири фотоперіоди: зима (січень), весна (березень), літо (липень) та осінь (жовтень). Нижчі рівні біомаркерів окиснювального стресу (p < 0,05) спостерігалося у молодших щурів у порівнянні зі старшими щурів, а також у високорезистентних щурів порівняно з низькорезистентними продуктів як основних індикаторів окиснювального стресу – збільшуються з віком, а влітку це призводить до подальшого підвищення в порівнянні з іншими сезонами. Крім того, біомаркери окиснювального стресу були нижчими (p < 0,05) взимку, ніж в інші сезони, особливо у високорезистентних щурів. Рівень загальної антиокиснювальної активності (ОАА) у тканині печінки 6-місячних щурів був достовірно вищим (p < 0,05) порівняно зі значеннями у щурів старшого віку. Подібно, більш високий рівень ОАА було виявлено в тканині печінки високорезистентних щурів порівняно з низькорезистентними. У дорослих високорезистентних щурів зберігався високий рівень ОАА із мінімальними змінами протягом року. Слід зазначити, що різниця в ОАА була вищою для груп дорослих тварин з високою резистентністю до гіпоксії взимку, навесні та влітку, що може свідчити про ефективні механізми, що перешкоджають утворенню активних форм кисню, та системи їх елімінації.
