Summary

自体血注射在本议定书中所描述的小鼠脑出血模型,采用双色注塑技术,以最大限度地减少了针轨道,在泵送系统中没有抗凝血剂的血液回流的风险,并消除了所有死在空间和系统扩展的油管。

Abstract

Investigation of the pathophysiology of injury after intracerebral hemorrhage (ICH) requires a reproducible animal model. While ICH accounts for 10-15% of all strokes, there remains no specific effective therapy. The autologous blood injection model in mice involves the stereotaxic injection of arterial blood into the basal ganglia mimicking a spontaneous hypertensive hemorrhage in man. The response to hemorrhage can then be studied in vivo and the neurobehavioral deficits quantified, allowing for description of the ensuing pathology and the testing of potential therapeutic agents. The procedure described in this protocol uses the double injection technique to minimize risk of blood reflux up the needle track, no anticoagulants in the pumping system, and eliminates all dead space and expandable tubing in the system.

Protocol

1。制备设备擦拭的立体框架,用75%乙醇和泵,以尽量减少细菌污染。 消毒汉密尔顿注射器和熔融石英针。 注意:如果使用化学灭菌,使用前一定要在无菌水冲洗数次。 石蜡纸的表面,并用75%乙醇擦拭,晾干。 2。制备注射鼠标注意:有交付给你的动物设施在手术前至少7天,让他们适应环境,以新的环境和减轻压力的小?…

Discussion

这在小鼠的自发性基底节出血重现模型中使用自体尾动脉的血液结果脑出血的手术模型。在小鼠的脑出血模型提供的转基因动物研究病理生理学的可用性的优势,但其体积小,使神经外科手术技术上更比在较大的动物困难。

胶原酶模型和自体血液的注入模型实验性脑出血的两个行之有效的模型。虽然胶原酶模型提供了一个简单的过程和高度重现性出血 2,使用细菌蛋?…
