摘要: 目的 研究安神补脑液对睡眠剥夺大鼠的学习记忆能力影响, 并从脑源性神经营养因子(BDNF)角度探讨其机理。方法 SD 大鼠, 随机分成正常对照组、正常对照+安神补脑液小剂量组及模型+蒸馏水组及模型+安神补脑液大、小剂量组。灌胃给予安神补脑液2 周后, 用多站台水环境法进行睡眠剥夺造模4 d , 用避暗法测试其学习记忆能力, 并取海马组织用Western blot 法测定BDNF 表达量。结果 与正常对照组比较, 睡眠剥夺大鼠避暗测试潜伏期显著减短, 表明出现学习记忆能力障碍;大剂量安神补脑液给药能显著延长模型大鼠的潜伏期, 表明该药可有效减轻大鼠睡眠剥夺后的学习记忆障碍。安神补脑液也能延长正常大鼠避暗实验的潜伏期。在睡眠剥夺大鼠海马组织BDNF 表达量显著降低,而用安神补脑液干预后模型大鼠BDNF 表达量增加, 在大剂量组出现显著性差异。结论 安神补脑液能提高睡眠剥夺鼠的学习记忆能力, 其机理之一可能与提高海马BDNF 含量有关。

Abstract: AIM: To study the effects of An-Shen-Bu-Nao syruP(AS)on the learning and memory ability and BDNF expression in the hippocampus of sleePdeprivation(SD)rats.METHODS: 75 rats were divided into groups of control , control +AS (0.02 ml·kg-1), SD +distillated water (DW), SD +AS (0.02 ml·kg-1), and SD +AS (0.06 ml·kg-1).All rats were fed with AS or DW for 2 weeks , and they were subjected to sleePdeprivation for 4 days , then the passive avoidance was tested for learning and memory.Also the BDNF expression in the hippocampus was tested with western blot after sacrifice.RESULTS: Compared with the control rats , SD rats had the significantly reduced latency in passive avoidance test , showing the decreased learning and memory ability.SD combined with AS (0.06 ml·kg-1) rats showed significantly longer latency than the SD rats (P<0.05), indicating the better learning and memory ability than the sleePdeprivation rats ;BDNF expression was significantly higher in the rats of SD combined with AS (0.06 ml·kg-1)than the SD rats.CONCLUSION: An-Shen-Bu-Nao SyruPcan effectively improve the learning and memory ability of sleePdeprivation rats , and the enhancement of BDNF expression may contribute to this effect.
