梗塞エリアの中央動脈閉塞技術と可視化を使用したマウスにおける虚血性脳卒中および虚血 - 再灌流の誘導

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.
