Biochemical and behavioural effects of hypoxic hypoxia in rats: study of the protection afforded by ergot alkaloids.

Abstract:

:The conditioned avoidance response and the cerebral levels of dopamine and noradrenaline have been studied in control rats and in rats submitted to a hypobaric hypoxia. A protection against the effects of hypoxia was induced by both dihydroergocornine (20 microgram/kg) and dihydroergocryptine (100 microgram/kg), and the noradrenaline level did not decrease. This stabilization of cerebral noradrenaline level seems to be the main protection factor observed.
