  • Title: [Damage to the hemato-encephalic barrier during one-time immobilization stress].
    Author: Belova TI, Iunson Iu.
    Journal: Biull Eksp Biol Med; 1983 Jul; 96(7):3-4. PubMed ID: 6683574.
    Abstract:
    Intravenous injection of trypan blue followed by treatment of the brain according to the Falc-Hillarp was used for morphological study of the blood-brain barrier in control rats and in animals exposed to the 6.5-hour stress. The density of the blood-brain barrier as regards the macromolecules in control animals was found to be liable to noticeable areal variations. The zones of primary increased barrier permeability were found near the basal surface of the brain. Prolonged single immobilization stress gave rise to destructive changes in the blood-brain barrier in the reticular formations of the midbrain and medulla oblongata. Besides, in control animals, there was a slight increase in permeability of the brain areas marked by the reduced barrier density.
