摘要

目的:研究转化生长因子β1（Transforming growth factor beta 1

TGF-β1）和α-平滑肌肌动蛋白（Alpha-smooth muscleaction

α-SMA）的表达差异与幼年和成年大鼠皮层注射FeCl3所致痫性发作的相关性

探讨其在大鼠痫性发作中的可能机制。方法:分别用FeCl3和生理盐水（Normal saline

N.S）注射幼年与成年大鼠皮层

观察大鼠痫性发作情况。ELISA法检测脑脊液（Cerebral spinal fluid

CSF）中TGF-β1变化

RT-PCR和Western免疫印迹法检测注射区域α-SMA表达。结果:只有幼鼠FeCl3组出现癫痫样发作;TGF-β1和α-SMA在幼鼠FeCl3组表达最高。结论:幼年比成年鼠更易并发癫痫发作

且TGF-β1和α-SMA表达更高

推断TGF-β1和α-SMA表达增加是幼鼠更易并发痫性发作的重要机制之一。

Abstract

Objective:To study the correlation between expressions of TGF-β1 & α-SMA and seizures of rats after intracortical injection of ferric chloride and explore its role in occurrence of rats seizure.Methods:Rats(childhood and adulthood) were treated with an intracortical injection of FeCl3 and normal saline

the occurrence of seizures were under observation;TGF-β1 in cerebral spinal fluid(CSF)was tested by ELISA;the expressions of mRNA and protein of α-SMA were detected by RT-PCR and Western blotting.Results:Epilepsy seizure was only observed in FeCl3 childhood group;TGF-β1 and α-SMA expression ranks top 1 in FeCl3 childhood group.Conclusion:Childhood rats were more susceptible to seizure than adulthood rats with higher level of TGF-β1 and α-SMA expressions;implying that the growth of TGF-β1 and α-SMA expressions might be the one of key mechanisms in seizure.
