[The study of the additive antioxidative activity of total natural lipid antioxidants]. / Izuchenie additivnogo antiokislitel'nogo deistviia summy prirodnykh antioksidantov lipidov.

Kinetics of methyl oleate and ethylbenzene oxidation was studied in presence of tocopherol homologues alpha, beta, gamma, delta, tocopherol derivatives C6 and C11, ubichinol QH2-9, which were isolated from natural lipids. Effects of various natural antioxidants in mixtures were interindependent.

[Effect of ionol and eleutherococcus on changes of the hypophyseo-adrenal system in rats under extreme conditions]. / Vliianie ionola i éleuterokokka na izmenenie organov gipofizadrenalovoi sistemy krys pri ékstremal'nom vozdeistvii.

Total adaptational syndrome, developed in response to a number of stress situations, is of importance in formation of accommodation reactions. Long-term and severe effects of the syndrome caused morphological and functional alterations in various tissues and body systems: adrenal gland hypertrophy, involution of thymus and spleen, ulcerous impairment of gastric mucosal membrane. At the same time, lipid peroxidation was increased while accumulation of the peroxidation products was observed, which are responsible for various body impairments.

[Chemiluminescent characteristics of ubiquinones]. / Khemiliuminestsentnye kharakteristiki ubikhinonov.

The paper deals with peculiarities of antioxidative activity of natural antioxidants (exemplified by ubiquinones) which permit their participation in the control of peroxidation intensity of membrane lipids. Ability of different ubiquinone forms to react with peroxide radicals is evaluated by chemiluminescent method. It has been shown that only reduced forms with free hydroxyl groups are highly effective.
