[Hemodynamic, functional and biochemical effects of hypobaric hypoxia in rats treated with cytidine diphosphocholine]

Treatment with cytidine diphosphocholine (20 mg/kg i.p.) in rats induces, during acute hypoxia, a reduction of vegetative responses (no modification of cerebral blood flow), a protection of conditioned avoidance response and a stabilization of dopamine and noradrenaline cerebral levels.
