Study of glutamate transporter function of hippocampus in seizures rats induced by KA / 临床神经病学杂志

ABSTRACT

Objective To study the change of glutamate transporter (GluTs) function of hippocampus in seizures rats induced by KA, and explore the role of GluTs in the mechanism of epilepsy.Methods 60 adult male Wistar rats were randomly divided into two groups: KA group(Ⅰ group) and control group(Ⅱ group). Each group was randomly divided into five subgroups according to different time after kindling, including 4 h, 24 h, 48 h, 5 d,and 7 d after injection. GluTs function was studied by means of assay of 3H-L-glutamate uptake in synaptosomes and tissue sections of hippocampus.Results The function of GluTs in synaptosomes was singnificently decreased at any time (all P
