title: [The effect of cholecystokinin octapeptide on ethanol-induced changes in motor activity and in dopamine metabolism in the nucleus accumbens of the rat brain].
abstract: The effect of intraventricular injection of cholecystokinin-octapeptide (CCK-8) in doses of 0.1875; 0.375; 0.75 and 1.5 micrograms/rat on the extracellular level of dopamine (DA) and its metabolites (DOPAC and HVA) after intraperitoneal injection of 1.5 g/kg ethanol was studied by microdialysis in n. accumbens of the brain of freely moving rats. CCK in a dose of 0.75 mg had no effect on the DA level, but significantly reduced the ethanol-induced increased DOPAC and HVA level. The effect of intraventricular injection of 0.75 microgram/rat CCK-8 on the motor activity of rats after intraperitoneal injection of ethanol (1.5 g/kg) was studied by the open field method. CCK-8 blocked the ethanol-induced inhibition of rat motor activity.
