The purpose of the present work to investigate the striatal neurotransmissors level in adult rats after status epilepticus induced by pilocarpine. Wistar rats were treated with a single dose of pilocarpine (400 mg/kg; s.c.; P400) and the controls received saline. Adult animals were closed observed for behavioural changes during 1h. In this period, the animals that developed status epilepticus and survive this acute phase of seizures had the brains removed and striatal neurotransmissors level determiden by HPLC. The concentration of dopamine, serotonine, dihydroxyphenylacetic acid was reduced and an concentration increase in 5-hydroxyindolacetic acid. Didn't observed alteration in 4-hydroxy-3-methoxy-phenylacetic acid. These results suggest that cholinergic activation can interage with dopaminergic and serotonergic systems in acute phase of the convulsive process in rat mature striatum.Downloads
