简介：
Overview
This article describes a surgical procedure to induce ischemic stroke in a mouse model by occluding the middle cerebral artery. The method allows for the external cerebral artery to remain intact, facilitating direct treatment infusion into the affected hemisphere.
Key Study Components
Area of Science
- Neuroscience
- Stroke Research
- Animal Models
Background
- Ischemic stroke is a critical area of study in neuroscience.
- Understanding treatment impacts on stroke severity is essential.
- Maintaining the external cerebral artery during occlusion is advantageous.
- This model can be used for both permanent occlusion and temporary ischemia.
Purpose of Study
- To reliably induce ischemic stroke in mice.
- To explore the effects of various treatments on stroke outcomes.
- To provide a model for studying stroke mechanisms and therapies.
Methods Used
- Mouse anesthesia with isoflurane and oxygen.
- Placement of a silicone-coated suture for artery occlusion.
- Monitoring of respiratory rate and reflexes during surgery.
- Post-stroke treatment infusion through the external cerebral artery.
Main Results
- The procedure successfully induced ischemic stroke.
- External cerebral artery remained intact for treatment infusion.
- Potential for further research into stroke therapies.
- Method demonstrated reliability and reproducibility.
Conclusions
- This model is a valuable tool for stroke research.
- It allows for direct treatment application post-occlusion.
- Further studies can build on this foundational technique.
What is the main goal of this surgical procedure?
The main goal is to reliably induce ischemic stroke while keeping the external cerebral artery intact for treatment infusion.
How is the mouse prepared for the surgery?
The mouse is anesthetized with isoflurane and placed on a prepared surgery surface.
What are the advantages of this stroke model?
The model allows for direct infusion of treatments into the affected hemisphere after stroke induction.
Can this method induce both permanent and temporary ischemia?
Yes, the protocol can be applied for both permanent occlusion and temporary ischemia followed by reperfusion.
What monitoring is required during the procedure?
The respiratory rate and reflex responses of the mouse must be monitored to ensure proper anesthesia.
What impact does this research have on stroke treatment?
This research can help answer key questions regarding the effectiveness of treatments on stroke severity.
