[Dynamics of oxygen tension in the brain and subcutaneous adipose tissue of newborn rats during anoxia and reoxygenation].
The oxygen tension (pO2) in the brain and subcutaneous tissue of newborn rats was studied during anoxia and reoxygenation with hyperoxic gas mixtures. The level of pO2 in both tissues during anoxia fell from 10-30 mm Hg to 0 mm Hg. When newborn rats were reoxygenated with 50% or 100% O2, the oxygen tension in the brain and subcutaneous first increased and then decreased in spite of the hyperoxic inhalation. The decrease of pO2 in the subcutaneous during hyperoxia was more pronounced than that in the brain. Data obtained are discussed.
