Abstract
The aim of the article. The article is devoted to investigation of of zinc donator acizol influence to rat’s behavior, broken by intrastriatal injection of GABA-A receptor antagonist picrotoxin.
Materials and methods. Adult male Wistar rats with avoidance conditioning reflexes in “shuttle box” and free locomotor activity in “open field” were used. Daily microinjection of picrotoxin (2 mcg/1 mcl) bilateral into rostral neostriatum in term of 15 days were made. Zinc donator acizol was injected intraperitoneal (24 mg/kg).
Results. Steady losses of avoidance conditioning and choreo-mioclonic hyperkinesis of limbs and body, similar with human Huntington’s chorea by picrotoxin were produced. Acizol is contribute to restore avoidance conditioning and to prevent the development of hyperkinesis or essentially extend latency and lover duration of it.
Conclusion. With the early data obtained, there is reason to propose, that acizol, to increasing the zinc content in the body, especially in the brain, is recover damaged cognitive function and to prevent the picrotoxin-induced hyperkinesis. Acizol should be proposed as perspective drug in extrapyramidal hyperkinetic deviation treatment in human.
