摘要

目的:观察经皮电刺激耳迷走神经支配的耳穴对颞叶癫痫大鼠自发癫痫发作频率、海马区胶质细胞活性及促炎细胞因子白细胞介素(IL)-6、抗炎细胞因子IL-10表达的影响

探讨耳穴刺激对颞叶癫痫的缓解效应及其可能的细胞与分子机制。方法:SD大鼠随机分为正常组、模型组、治疗组

每组12只。采用氯化锂-匹罗卡品多次小剂量重复注射制备慢性颞叶癫痫大鼠模型。对治疗组耳甲腔内耳穴"心""肺""皮质下"进行经皮电刺激干预

每日1次

每次20min

治疗6周。用长时程视频系统监测大鼠的癫痫发作情况

治疗后用免疫荧光与Real-time PCR方法观察癫痫大鼠海马区小胶质细胞标记物Iba 1、星形胶质细胞标记物胶质纤维酸性蛋白(GFAP)及IL-6、IL-10的表达情况。结果:模型组大鼠癫痫自发频率随时间延长显著增加

治疗组大鼠的自发癫痫频率较模型组显著降低(P<0.05)。与正常组比较

模型组大鼠海马CA 1、CA 3区Iba 1、GFAP、IL-6免疫阳性细胞数明显增多(P<0.05)

IL-6mRNA表达水平显著上调(P<0.05)。与模型组比较

治疗组大鼠海马CA 1、CA 3区Iba 1、GFAP、IL-6免疫阳性细胞数明显减少(P<0.05)

IL-6mRNA表达水平显著下调(P<0.05)

IL-10阳性细胞数及mRNA表达水平显著上调(P<0.05)。结论:耳迷走神经支配的耳穴经皮电刺激干预能显著降低慢性颞叶癫痫大鼠的癫痫发作频率

此效应可能与下调海马区胶质细胞活性

下调海马内促炎细胞因子IL-6

上调抗炎细胞因子IL-10的蛋白及基因表达水平密切相关。

Abstract

Objective To observe the effect of transcutaneous otopoint electrostimulaiton(TCOES)on seizure frequency

immunoreactivity of hippocampal gliocytes and expression of proinflammatory cytokine interleukin-6(IL-6)and anti-inflammatory cytokine IL-10 in chronic temporal lobe epilepsy(CTLE)rats

so as to investigate its antiepileptic mechanism.Methods Thirtysix SD rats were randomly divided into control

model and TCOES groups(n=12in each group).The CTLE model was established by intraperitoneal injection(i.p.i.)of lithium chloride(127.2mg/kg)

scopolamine(1mg/kg

20 hafter the 1st injection)and pilocarpine(10mg/kg

30 min after scopolamine injection).Rats of the control group were treated by i.p.i.of normal saline.TCOES(1mA

20Hz)was applied to bilateral otopoint"Heart"-"Lung"-"Subcortex"region for 20 min

once daily for 6weeks.The epileptic attack was observed by a video monitoring system.The numbers of ionized calcium-binding adapter molecule-1(Iba 1)-labeled microgliacytes and glial fibrillary acidic protein(GFAP)-labeled astrocytes in the CA 1and CA 3regions of hippocampus were counted under light microscope after immunostaining

and the expression levels of hippocampal IL-6and IL-10 proteins and genes were determined by immunofluorescence and quantitative real-time PCR

respectively.Results After TCOES intervention

the seizure frequency was significantly decreased in comparison with pre-treatment(P<0.05)

modeling-induced dramatic increase of the numbers of microgliacytes and astrocytes

IL-6immunoactivity in the hippocampal CA 1and CA 3regions

and IL-6mRNA expression in the hippocampus were significantly suppressed(P<0.05)

and hippo-campal IL-10 immunoactivity and mRNA expression were considerably up-regulated in comparison with the model group(P<0.05).Conclusion TCOES intervention has an antiepileptic effect in CTLE rats

which may be associated with its effects in suppressing gliocyte proliferation

suppressing the expression of proinflammatory cytokine IL-6

and up-regulaiting the expression of anti-inflammatory cytokine IL-10 in the hippocampus.
