Objective:To establish an ex-vivo epileptic model by investigating hippocampal neurons epileptiform discharge induced by magnesium-free extracellular fluid. Methods:Neonatal Wistar rats(<24h old) were adopted to draw hippocampal neurons for primary culture
and the neurons were identified by immunofluorescence of NSE. On day 9
neurons were treated with magnesium-free extracellular fluid for 3h
then
the discharge activity at certain time points were recorded by whole-cell patch clamp. Results:Through identification
the purity of cultured neurons was high to 100%. After treated with magnesium-free extracellular fluid for 3h
the neuronal epileptiform activity was observed
which continued to exist until the culture fluid returned to be normal for 24h. Conclusion:Epileptiform discharges of neurons exposed to magnesium-free extracellular fluid for 3h were stabile
hich provided a new epileptic model for pathogenetic research of epilepsy.
