Status epilepticus (SE) is a severe condition that may lead to hippocampal cell loss and epileptogenesis. Some of the mechanisms associated with SE-induced cell death are excitotoxicity, neuroinflammation, and apoptosis.
The objective of the present study is to test the hypothesis that DBS has anti-inflammatory and antiapoptotic effects when applied during SE.
Rats undergoing pilocarpine-induced SE were treated with anterior thalamic nucleus (AN) deep brain stimulation (DBS). Inflammatory changes and caspase 3 activity were measured within 1 week of treatment.
In pilocarpine-treated rats, DBS countered the significant increase in hippocampal caspase 3 activity and interleukin-6 (IL-6) levels that follows SE but had no effect on tumor necrosis factor α (TNFα).
DBS has anti-inflammatory and antiapoptotic effects when given to animals undergoing status.
癫痫持续状态（SE）是一种严重病症，可能导致海马体细胞丢失和癫痫发生。与SE诱导的细胞死亡相关的一些机制是兴奋性毒性、神经炎症和细胞凋亡。
本研究的目的是检验以下假设：在SE期间应用脑深部电刺激（DBS）具有抗炎和抗凋亡作用。
对接受匹鲁卡品诱导的SE的大鼠进行丘脑前核（AN）深部脑刺激（DBS）治疗。在治疗1周内测量炎症变化和半胱天冬酶3活性。
在匹鲁卡品治疗的大鼠中，DBS对抗了SE后海马体半胱天冬酶3活性和白细胞介素-6（IL-6）水平的显著升高，但对肿瘤坏死因子α（TNFα）没有影响。
对处于癫痫持续状态的动物给予DBS具有抗炎和抗凋亡作用。
