Abstract:
:In the brain, injury-induced gliosis and axonal sprouting have been regarded as age-dependent repairing processes with, unfortunately, epileptogenic effects. The present study examines whether brains injured at different developmental stages become more or less susceptible to experimentally-induced status epilepticus. In 6- and 30-day-old Wistar rats (P6s and P30s, respectively), a mechanical injury was performed in the cortex of the left cerebral hemisphere. On postnatal day 60, all the animals and naïve controls received single intraperitoneally pilocarpine injections to evoke status epilepticus. During a 6-h period following the injection, the animals were observed continuously and motor manifestations of seizure activity were recorded and rated. Seven days after pilocarpine injection, the animals were perfused and their body and brain weights recorded. When compared to controls, P6s showed neither significant variations in their epileptic behavior nor in brain and body weights. In relation to controls and to P6s, P30s presented an extremely high mortality, a significant loss of body weight and much longer-lasting seizures of much higher intensity. The data provide evidence that the long-term variations in susceptibility to experimentally-induced status epilepticus are determined by differences in the brain response to injury at different stages of postnatal development.
