摘要 目的探讨热休克蛋白70(HSP70)在不同发作级别的癫痫大鼠海马结构的表达及意义。方法采用戊四氮致痫模型,随机分为对照组和模型组,模型组按癫痫发作级别又分为Ⅰ级、Ⅲ级、Ⅴ级组。采用免疫组织化学方法观察不同级别癫痫发作海马内HSP70表达的变化;常规病理学染色观察各组海马区神经元的受损情况。结果对照组与Ⅰ级组海马结构内未见HSP70免疫反应阳性细胞,而Ⅲ级组、Ⅴ级组海马各区的HSP70阳性细胞数与对照组比较逐渐增多(P<0.05)。病理检查发现,Ⅲ级、Ⅴ级组海马结构内存在受损异常神经元,Ⅴ级组更明显。结论戊四氮致痫癫痫模型中,随着发作级别的增加,海马结构内神经元损伤渐加重,HSP70的表达亦逐渐增加,提示海马结构HSP70的表达与癫痫发作严重程度有关。
