Interruption of the corticostriatal pathway by undercutting the frontal cortex resulted after 2 weeks in a 40% reduction of basal acetylcholine (ACh) release in vivo, and in inhibition of the striatal sodium-dependent high-affinity uptake of choline (SDHACU) to the same extent. The lesion, too, completely prevented the rise (about 35%) in striatal ACh(More)
Since 1989 we performed stereotactic radiotherapy treatments of cerebral arterovenous malformations (AVM), estimating three-dimensional (3-D) localization and shape of target volumes by the Leksell stereotactic helmet on two orthogonal radiographic projections. Due to the limitations of this method, we developed a new technique for the localization of the(More)
The effects of nicergoline on basal and K(+)-stimulated release of ACh in the hippocampus of 3- and 19-month old rats has been studied by microdialysis. A significant decrease of basal ACh release (59%) was found in aged vehicle treated rats in comparison to young rats. High-K+ (100 mM) in the perfusate strongly increased the release of ACh by up to 6-fold(More)
Basal and agonist-stimulated phosphoinositide (PI) turnover and inositol 1,4,5 -trisphospate (InsP3) content in rat brain were investigated after chronic nicergoline (SERMION) treatment. Oral administration of nicergoline (5 mg/kg b.i.d. for 7 weeks) enhanced the basal turnover of PI in the cerebral cortex compared to controls. This effect was paralleled by(More)
Tiaspirone, a potential antipsychotic drug, reduced the acetylcholine content of rat hemispheric brain regions (striatum 35%, hippocampus 20%, cortex 32% with no effect on N. accumbens) at an oral dose of 40 mg/kg. Choline content was uniformly raised in the same brain regions. A kinetic study showed that the drug is evenly distributed in the brain.(More)
