Abstract

A decrease of taurine in hippocampus of the line of rats with pendulum movements (PM), predisposed to audiogenic epilepsy, was shown. Taurine (aminoethanesulfonic acid) is known to be an anticonvulsant drug. The aim of the present work was to verify the predictive validity of taurine in rats with pendulum movements (PM). In neonatal period the exogenous taurine administration did not influence a convulsive activity at the age of 1.5 and 3 months in PM rats. The increase in the number of audiogenic seizures after taurine injections was found in adolescent period in 1.5 months and in prolonged point – in 3 months. The number of abortive seizures decreased under acute injection of taurine in adult PM rats, but the level of ictal and postictal indicators restored one month later, at the age of 4 months. Obtained results indicate the absence of effect of taurine administered to rats in the neonatal age, while at the long-term scale, the rats showed the increasing seizure activity under the action of taurine in adolescent period and confirm the predictive validity of this drug in adult PM rats.
