title: [Adaptation to low intensity positive radial acceleration during early ontogenesis].
abstract: In 5, 12, and 25 day old laboratory rats of our own breeding LD50 for positive radial acceleration of the intensity of 5 g, 7.5 g and 10 g was established. Resistance was found to decrease with age. All animals exhibited full adaptation on repeated exposure to acceleration of 5 g or 7.5 g, and even 10 g over a period corresponding to 20% duration of the lethal dose for the initial age applied 3 times a day in 3 hour intervals. The resistance of the animals to oxygen deficiency was significantly increased as demonstrated by the survival of all animals 3 hours after their exposure to 10 g acceleration in a dose lethal for the given age. Adaptation is presumed to occur at tissue level.
