简介：
Overview
This study modifies an existing experimental method to enhance reproducibility by establishing a middle cerebral artery occlusion (MCAO) mouse model. The oral administration of Glycyrrhizae Radix et Rhizome (GR) methanol extract (GRex) post-stroke induction significantly reduced total infarction volume compared to the untreated control group.

What is the MCAO model?
The MCAO model is a widely used experimental method to simulate stroke in animal studies.
How is GRex prepared?
GRex is prepared by incubating Glycyrrhizae Radix et Rhizome in methanol for five days and then filtering the solution.
What are the benefits of using GRex?
GRex has shown potential neuroprotective effects, reducing infarction volume in stroke models.
Why is reproducibility important in research?
Reproducibility ensures that results are reliable and can be confirmed by other researchers.
Who conducted the visual demonstration of the MCAO procedure?
The procedure was demonstrated by Se-Eun Lee, a student in the laboratory.
