The present behavioral study was undertaken to investigate whether neuronal nitric oxide (NO) synthase mediates the abnormal consequences of increased NMDA receptor-mediated synaptic transmission in models of postural tremor, Parkinson's disease and epilepsy. We used 7-nitroindazole, a selective
Glutamate uptake into synaptic vesicles is a vital step for glutamatergic neurotransmission. Quinolinic acid (QA) is an endogenous glutamate analog that may be involved in the etiology of epilepsy and is related to disturbances on glutamate release and uptake. Guanine-based purines (GBPs) guanosine
Status epilepticus was produced in rats by administering pilocarpine (30 mg/kg, s.c.) 16 h after treatment with LiCl (3 meq/kg, i.p.). After 35 min of status epilepticus, several parameters of cholinergic activity were measured. Seizures had no effect on the in vivo concentration of acetylcholine or
Studies on the purinergic system normally deal with adenine-based purines, namely, adenine nucleotides and adenosine. However, a guanine-based purinergic system may also have important neuromodulatory roles. Guanine-based purines exert trophic effects on neural cells, protect brain slices in a model
