Abstract:
AIM: To quest the relationship bwteen BDNF and seizures. METHODS: BDNF and other correlative proteins in the hippocampus of audioepileptic rat (P77PMC) have been detected by immunohistochemistry at different stages of seizures including quiet stage, preconvulsive stage, convulsive stage and postconvulsive stage. Wistar rats were served as controls. RESULTS: At quiet stage, the BDNF in the hippocampus of P77PMC were less than that of control group and stepped up after stimulation, trkB in the hippocampus of P77PMC were high at every stages, but PY20 were increased only after stimulation. NPY in the hippocampus of P77PMC were in a low level before seizures. CONCLUSION: The endogenetic BDNF may alter the excitement of P77PMC by adjusting the expression of NPY in hippocampus and activating its receptor trkB.
