[Influence of antibodies to the glutamate on convulsive reaction to mice C57Bl/6 in term of chronic epileptogenesis].

It was shown that the preliminary single i.p. injection of antibodies (AB) to glutamate (GLU) 1,5 hours prior to the first injection pentylenetetrazole (prior to the beginning of kindling) did not have an effect on latency period of appearance and the severity of convulsive reactions in the mice of C57Bl/6. The administrations of AB to GLU at the different stages of kindling animals with different severity of seizures did not have an effect on their severity. Thus, AB to GLU did not posses antiepileptic effect. However, AB to GLU posses anticonvulsive action on the acute seizures reaction, inducing an increase in the thresholds of clonic seizures and tonic phase seizures with lethal outcome as well as an extended latency period of occurrance these seizures in mice with enhanced kindling-producing convulsive readiness of the brain. This effect was revealed at the different stages of kindling in animals with the severity of seizures 2-3 and 4-5 marks. Possible to assume, that the mechanisms of chronic epileptogenesis (in this case, in the form kindling-dependent enhanced convulsive readiness of the brain) and those of the acute convulsive reaction are not similar.
