Resumo: | Epilepsy is the most common neurological disorder, affecting 50 million people worldwide, 40 million of them in developed countries. People of all races, genders, socioeconomic conditions and regions are affected. The pilocarpine (P400) is a cholinergic agonist characterized by inducing seizures evolving to status epilepticus, similar to human temporal lobe epilepsy. The pentylenetetrazole (PTZ) is a GABA antagonist that mimics the small-mal seizures (absence seizure) and tonic-clonic seizures in humans. The strychnine is a potent convulsant and acts mainly as a selective antagonist of postsynaptic inhibition mediated by glycine. Its main action is to increase the excitability of the spinal reflex . The convulsant picrotoxin is an agent that blocks chloride channels activated by gamma-aminobutyric acid. Convulsant agents were administered intraperitoneally, 10 minutes after intravenous administration of carbapenÃmcios With the development of this work, we found that pretreatment with imipenem or meropenem interfere with various neurotransmitter systems when animals are subjected to seizures induced by pilocarpine at a dose of 400mg/kg, 55mg/Kg at a dose of pentylenetetrazole, strychnine and picrotoxin 10mg/Kg 2mg/kg. This has been evidenced by increasing levels of excitatory amino acids such as glutamate and on the other hand, a decrease in levels of inhibitory amino acids such as GABA reinforcing the existence of a possible modulatory pathway of these amino acids in control and development of seizure occurs when pre-treatment with imipenem or meropenem. |
