    Abstract:
    In experiments on mice C57Bl/6 was studied effects of citicoline (500 mg/kg, i.p.) on development of chronically epileptization of the brain--pentylenetetrazole (PTZ) kindling (30 mg/kg PTZ, i.p. during 24 days) and on acute generalized seizures (i.v., 1% solution of PTZ with the speed of 0.01 ml/s). It was shown that daily injection of citicoline an hour before the introduction of PTZ had no effect on development of chronically epileptization of the brain --PTZ-kindling (the latency of seizures appearance and their severity). However, citicoIine posses anticonvulsive effects on acute seizures in kindled mice. In animals with increased seizure susceptibility of the brain caused by kindling and severity of seizures 2-3 points injection citicoline after 14 days of kindling had anticonvulsive effect, increasing the threshold clonic seizures. Injection of citicoline during 24 days of kindled animals and severity of seizures 3-5 points caused the increase of thresholds as clonic and tonic phase of seizures with lethal outcome. Thus, the anticonvulsant effect of citicoline more pronounced in the long-term use.
