title: [Hypobaric hypoxia effects on a conditioned avoidance response and on ADP, AMP dopamine and noradrenaline cerebral levels in rats treated or not with naftidrofuryl (author's transl)].
abstract: Hypobaric hypoxia (300 mm Hg = 7180 m) was performed during 30 min. for a day during five consecutive days in rats treated or not with naftidrofuryl (15 mg/kg- i.p. daily). A conditioned avoidance response studied on five days shows a reduction of the performances in control rats but not ir treated ones. AMP and ADP cerebral levels were unchanged in the two groups. Hypoxia induced in control rats a reduction of the catecholamine cerebral levels which was not observed in treated rats. In conclusion the protection afforded by naftidrofuryl seems to be due mainly to a reduction of the catecholamine utilization during hypoxia.
