摘要 目的 :探讨岗田酸所致的氧化应激反应与谷氨酸转运体功能的关系及银杏叶制剂的影响。方法 :采用侧脑室注射岗田酸法测定假手术对照组、岗田酸注射组、岗田酸注射组加银杏叶制剂组皮层、海马谷氨酸转运体功能的变化及SOD活性 ,MDA含量的变化。结果 :岗田酸注射组谷氨酸转运体功能降低 (P <0 0 5 ) ,SOD活性降低(P <0 0 5 ) ,MDA含量升高 (P <0 0 5 ) ,岗田酸注射组加银杏叶制剂组 ,谷氨酸转运体功能较岗田酸注射组有明显恢复 (P <0 0 5 ) ,与对照物无明显差异。SOD活性回升 (P <0 0 5 ) ,MDA含量下降 (P <0 0 5 )。结论 :大鼠注射岗田酸后 ,皮层、海马谷氨酸转运体功能降低 ,可能与氧化应激产生的自由基有关 ,银杏叶制剂通过抗氧化应激反应 ,恢复谷氨酸转运体功能来发挥保护作用。
