title: [Effects of nicotinic cholinoreceptor ligands and nootropic drugs on the spontaneous exploratory activity in a labyrinth in mice].
abstract: We have studied the effects of nicotine (0.125, 0.25, and 0.5 mg/kg) and mecamylamine (0.5, 1.5, and 3 mg/kg) in comparison to reference cognition-enhancing drugs piracetam (100 and 300 mg/kg) and meclofenoxate (20, 50, and 100 mg/kg) administered to male C57BL mice intraperitoneally 30 min prior to behavioral test. The behavioral drug effect was evaluated as influencing the activity in visiting arms of a closed plus-maze. Piracetam (300 mg/kg) and meclofenoxate (100 mg/kg) improved the exploratory activity. Mecamylamine (0.5 mg/kg) also improved the exploratory activity, while nicotine (0.5 mg/kg) deteriorated it.
