目的:观察酸枣仁总皂苷对老年阴血亏虚证失眠大鼠脑组织谷氨酸(Glu)、γ-氨基丁酸(GABA)及GABA A受体表达的影响。方法:将Wistar大鼠随机分为空白对照组(等容生理盐水),模型组(老年阴血亏虚证失眠组,等容生理盐水),阳性对照组(安定0.18 ...目的:观察酸枣仁总皂苷对老年阴血亏虚证失眠大鼠脑组织谷氨酸(Glu)、γ-氨基丁酸(GABA)及GABA A受体表达的影响。方法:将Wistar大鼠随机分为空白对照组(等容生理盐水),模型组(老年阴血亏虚证失眠组,等容生理盐水),阳性对照组(安定0.18 mg·kg-1·d-1),酸枣仁总皂苷低、高剂量组(15,30 g·kg-1·d-1)。用D-半乳糖致亚急性衰老、环磷酰胺及氢化可的松致阴血亏虚,及自制改良多平台法剥夺快动眼睡眠(REM)48 h,制作阴血亏虚证候失眠老年大鼠模型。造模后各组灌胃给药3周,采用高效液相法检测脑皮质、海马部位Glu,GABA含量;免疫组化染色及RT-PCR法检测脑皮质、海马部位GABA A R的表达变化,并考察酸枣仁总皂苷对这些指标的影响。结果:与空白对照组比较,模型组大鼠脑皮质及海马Glu,GABA含量显著升高(P<0.01,P<0.05),且Glu/GABA增高;脑皮质及海马部位的GABA A R免疫化学累积吸光度明显较高(P<0.01);皮质部位GABA A R mRNA的表达均显著上调(P<0.01),经酸枣仁总皂苷干预后各指标明显下降(P<0.01,P<0.05)。结论:酸枣仁总皂苷治疗阴血亏虚证老年失眠的机制可能与减少脑内氨基酸毒性作用,下调大脑皮质及海马部位GABA A R的表达有关。展开更多
