摘要
目的 观察氟哌啶醇对大鼠离体海马脑片和原代神经元的缺糖 缺氧 (OGD)和N 甲基 D 天冬氨酸 (N methyl D aspartate ,NMDA)损伤的潜在保护作用及其机制。方法 海马脑片OGD以无葡萄糖的人工脑脊液中通 95 %N2 +5 %CO2 诱导。通过测定TTC染色后形成的红色产物来分析脑片活性。结果 氟哌啶醇 (1和 10 μmol·L- 1 )抑制OGD损伤 ,抑制率分别为 17 7%和 2 5 %,而D2 多巴胺受体拮抗剂多潘立酮无此作用。NMDA也能显著降低海马脑片及原代神经元的活性 ,而氟哌啶醇可抑制这一损伤作用。结论 氟哌啶醇对大鼠离体海马脑片OGD和原代神经元NMDA损伤有保护作用。
