Effect of gap junction blockers on hippocampal ripple energy expression in rats with status epilepticus / 中国当代儿科杂志

ABSTRACT

OBJECTIVES@#To study the effect of gap junction blockers, quinine (QUIN) and carbenoxolone (CBX), on hippocampal ripple energy expression in rats with status epilepticus (SE).@*METHODS@#A total of 24 rats were randomly divided into four groups: model, QUIN, valproic acid (VPA), and CBX (@*RESULTS@#Ripple expression was observed in the hippocampal CA1, CA3, and dentate gyrus regions of normal rats. After 10 minutes of PILO injection, all groups had a gradual increase in mean ripple energy expression compared with 1 day before modeling, with the highest expression level before chloral hydrate injection in the model, VPA and CBX groups (@*CONCLUSIONS@#The change in ripple energy can be used as a quantitative indicator for early warning of seizures, while it cannot predict seizures in the interictal period. Gap junction blockers can reduce ripple energy during seizures.
