Abstract
We investigated the effect of vinpocetine
on brain monoamines in rats with experimentally induced cerebral
ischemia, using fluorescent histochemical techniques. The results indicate that 1)
vinpocetine reversed the decreased brain tissue
levels of catecholamines and serotonin following experimental cerebral
ischemia; 2) the compound also facilitated the turnover of catecholamines and serotonin in the brain. These facts suggest that
vinpocetine, with its proven
actions to facilitate the turnover of rnonoamines in the brain and to improve impaired monoamine metabolism in experimental cerebral
ischemia, might prove effective in augmenting cerebral blood flow.
