The effect of alcohol-aqueous extract (1:1) from Rhodiola rosea L. roots on the processes of learning and memory is studied on rats. Several methods of active avoidance with negative and positive reinforcements are used, as well as of passive avoidance. Using the maze-method with negative (punitive) reinforcement, it has been found that Rhodiola extract in(More)
Ethopharmacological techniques were used to study the behaviour of the offspring of mice treated with different drugs before and after parturition. The "standard opponent" test was used and the animal's behaviour was recorded on videocassettes. It was found that ethyl alcohol, glutamate, cyproterone acetate, medroxyprogesterone acetate, corticosterone and(More)
The effects of adafenoxate (Adf), meclofenoxate (Mf), piracetam (Pc), and citicholine (CCh) on scopolamine (Scop)--impaired memory and exploratory behavior (experiments on rats) and on physical capabilities (experiments on mice) were studied. In the experiments with scopolamine (2 mg/kg i.p.) we used the step-through passive avoidance method to determine(More)
In experiments on albino rats, the authors studied the effects of meclofenoxate and Extr. Rhodiolae roseae on the memory-impairing action of convulsant electroshock. "Step-down" passive avoidance training with negative reinforcement was used to trace the changes in memory. Meclofenoxate administered i.p. in a dose of 100 mg/kg body weight for five days(More)
1. The effects of Adafenoxate (Adf), meclofenoxate (Mf) and citicholine (CCh) administered at a daily dose of 100 mg/kg for 7 days on the levels of noradrenaline (NA), dopamine (DA) and serotonin (5-HT) in the frontal cerebral cortex, striatum, hippocampus and hypothalamus of rats were studied. 2. Adafenoxate increased the NA level in the striatum and(More)
