マウスにおける自発脳内出血をモデル化する自家血注入
Summary
このプロトコルで説明されているマウスの脳内出血の自家血注入モデルでは、針のトラックまでの血液逆流、ポンプシステムにおける無抗凝固剤のリスクを最小限に抑えるために二重注入の技術を使用し、システム内のすべてのデッドスペースと拡張可能なチューブを排除。
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.

自発的な基底核出血の再現可能なモデルで自家尾動脈の血液の結果を使用してマウスの脳内出血のこの外科的モデル。マウスにおけるICHのモデルは、病態生理を調査するためにトランスジェニック動物の可用性の利点を提供しているが、その小さなサイズが大きい動物よりも脳神経外科手術はより技術的に困難になります。
