title: [Changes in the physical condition, vestibular function and bone system in rats exposed to long-term rotation].
abstract: The unrestrained rats were rotated for 21 and 30 days at 1.1 and 2.0 G. The exposure did not deteriorate their equilibrium function or physical condition, i. e. static and dynamic endurance. However, the exposure decreased the reactivity and sensitivity of the semicircular canals. Bone parameters-longitudinal and transverse bone growth, metaepiphysis morphometry-indicated that the rats developed an acute stress-reaction accompanied by an inhibited growth of limb bones during the first 7 days of rotation. By experimental day 30 the animals became adapted to the new environment.
