Eigenblut Injection zu Spontane intrazerebrale Blutungen in Mäuse-Modell
Summary
Die Eigenblut Injektion Modell der intrazerebralen Blutung bei Mäusen in diesem Protokoll beschriebenen Verwendungen der doppelten Einspritzung Technik, um das Risiko von Blut Reflux bis die Nadel Spur, keine Antikoagulanzien in das Pumpsystem zu minimieren, und eliminiert alle Totraum und erweiterbar Schlauch in das System.
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.

Discussion
Dieses chirurgische Modell intrazerebralen Blutungen in Mäusen unter Verwendung autologer Schwanzarterie Blutwerte in ein reproduzierbares Modell der spontanen Basalganglien Blutung. Eine ICH-Modell bei Mäusen hat den Vorteil der Verfügbarkeit von transgenen Tieren zu Pathophysiologie untersuchen, jedoch macht ihre geringe Größe neurochirurgische Verfahren technisch schwieriger als in größeren Tieren.
Die Collagenase-Modell und die Eigenblut Injektion Modell sind zwei etablierte Model…
