摘要(Abstract):
目的观察β-榄香烯对神经病理性疼痛模型大鼠神经功能保护及对模型大鼠脊髓背根神经节ERK mRNA、CREB mRNA、BDNF mRNA表达的的影响。方法建立神经病理性疼痛大鼠模型,对各组大鼠进行热痛觉过敏行为测试;Realtime PCR检测模型大鼠脊髓背根神经节ERK mRNA、CREB mRNA,以及BDNF mRNA表达。结果假手术组无明显神经功能障碍;与模型组比较,中药组(β-榄香烯)能明显上调模型大鼠热板及机械刺激后的痛阈(P<0.05或0.01),且ERK mRNA、CREB mRNA以及BDNF mRNA的表达较模型组明显上调(P<0.05或0.01)。结论β-榄香烯可改善模型大鼠热痛觉,上调神经病理性疼痛模型大鼠脊髓背根神经节ERK mRNA、CREB mRNA、BDNF mRNA表达从而促进神经元修复。
