摘要

目的:观察椎管内注射眼镜蛇毒najanalgesin对大鼠L5脊神经结扎并剪断(spinalnerve ligation and transection,SNL)术后脊髓谷氨酸-天冬氨酸转运体GLAST(glutamate-asparate transporter,GLAST)mRNA表达的影响,探讨najanalgesin脊髓镇痛机制。方法:采用L5SNL模拟神经病理性疼痛,von Frey hair测定大鼠术侧后足50%机械刺激撤足反射阈值(50%paw withdrawal threshold,PWT)判断模型成功,real-time PCR检测SNL 7 d后脊髓L4-L6GLAST ...
