Objective: To observe the contribution of Qingnao drop pilula to the alteration of myristoylated alanine-rich C kinase substrate mRNA expression in acute multi-infarction hippocampus.

中文摘要：目的：观察清脑滴丸对急性脑缺血海马MARCKS mRNA表达变化的影响，探讨其对急性脑缺血损害的调节作用。

Qingnao drop pilula can alleciate histomorphology lesion of hippocampus when occurring acute multi-infarction, to turn slower MARCKS mRNA expression, may play a neuroprotective effect role through accommodating PKC-MARCKS signal transduction system.

清脑滴丸可以减轻急性脑缺血时海马组织损伤，下调MARCKS mRNA的过高表达，其机制可能是通过调节PKC-MARCKS信号转导系统而起到神经保护作用。
