Result:Results show that AchT immunoreactive neurons locate in dorsolateral and dorsomedial to genu of the facial.Few neurons scatter in the parvocellular nucleus.

结果：大鼠胆碱乙酰转移酶阳性传出性前庭神经元分布在面神经膝内侧E群、背外侧E群及脑桥尾侧网状核，以内侧E群为主。

The mechanism may be related to reducing brain cholinesterase activity, inhibiting the accumulation of aluminium ions in brain, maintaining the normal level of Glu/GABA.Key words:Prepared Radix Rehmanniae; Learning and memorizing; Dysmnesia

结论熟地黄对于化学药品所致记忆障碍模型小鼠具有增强其学习记忆和空间记忆能力的作用，其作用机制可能与改善中枢胆碱能神经系统功能，降低脑内Al3 含量，保护脑组织及维持脑内Glu/GABA的正常水平有关。

The mice were then challenged with inhaled methacholine and respiratory system impedance tracked for the following 10 minutes. Respiratory elastance was estimated from each impedance measurement.
