Methods (1) The experiments of quick decapitation and anoxia under normal pressure model in mice was used to study the effects of LW on acute cerebral ischemia and anoxia.
方法：（1）采用小鼠断头实验和常压耐缺氧实验，观察LW对脑组织急性缺血缺氧的保护作用；
2
We used anoxia test in the natural atmospheric pressure to detect effect of Runshen oral liquid on the mice resistance to anoxia .
