title: [Ultrastructural manifestations of blood-tissue barrier reactions to acute hypoxia in old animals].
abstract: Readjustments occurring in different blood-tissue barriers (the brain, endocrine glands, heart, liver, jejunum) in response to acute hypoxia in old animals develop against the background of the preceding age-specific changes, including the adaptive ones. This results, first, in a significant narrowing of the adaptive reaction range and, second, acceleration and deepening of destructive processes in tissues and prolongation of the restoration period.
