[Age-dependent characteristics of blood plasma oxidative and antioxidative reactions to the hypobaric hypoxia and different duration of the photoperiod].
The effect of hypobaric hypoxia (6 hours everyday 7 days) under different duration of the photoperiod on oxidative (malonic aldehide and dienal conjugates) and antioxidative (catalase and superoxide dismutase activity) systems in the blood plasma of adult and infantile albino male rats were investigated. It is concluded that there is an age-dependent reaction of oxidative and antioxidative systems to the combined action of hypobaric hypoxia and different duration of the photoperiod. Reactions of pro- and antioxidative systems of adult and infantile rats were approximately the same under the conditions of a long-term darkness-and hypoxia but in the infants they were less manifested under the combined action of hypoxia and natural light or long-term lightening. Hypoxia combined with all varieties of photoperiod activate antioxidative system in both age groups but only in infantile rats the process of peroxidation was reducing.
