The effects of tabernanthine on serotonin (5-HT) levels were determined in several brain areas of rats exposed to various simulated altitudes (1800, 5200, 7000 m). The 5-HT synthesis inhibitor, para-chlorophenylalanine (PCPA), was used to dissociate the effects occurring at synthesis and release
The central effects of tabernanthine on noradrenaline and dopamine turnover times were studied in the hypothalamus, the striatum and the remainder of the brain of normal and hypobaric hypoxic rats, the latter state corresponding to 5,200m (410mm Hg) and 7,000m (320mm Hg). Catecholamine cerebral
Tabernanthine increased the synthesis and elimination of catecholamines (CA) in the striatum and the rest of the brain, but not in the hypothalamus. These data provide evidence that tabernanthine may activate CA turnover of some brain structures by acting at 2 steps of the metabolic pathway. The
