title: [Effect of intermitent hypoxia on ultrastructure and prooxidant-antioxidant balance in the soft tissue of the periodontium in acute immobilization stress].
abstract: The changes of prooxidant-antioxidant balance and morphofunctional state of soft tissue of paradontum under the acute immobilization stress, intermittent hypoxia and its complex influence were investigated. It was shown, that intermittent hypoxia can stimulate own endogenous mechanisms of nonspecific resistance, such as antioxidant protection in soft tissue of paradontum. Normalization of the prooxidant-antioxidant balance under immobilization stress after intermittent hypoxia essentially improved the morphofunctional state of tissue investigated with decrease of edema and improvement of mitochondria apparatus ultrastructure.
