20 yıl önce anlayışı bu yana, bir filamanın sokulmasını kapsayan insan inme için MCAO modeli çalışmaları çok sayıda kullanılmıştır. Bunun nedeni o inme (yani, iskemik inme) en sık görülen klinik ne taklit gerçeği esas olarak. striatum serebral korteks daha iskemi karşı daha duyarlıdır ve bu nedenle, iskemik sürenin uzunluğu striatum ve dorsolateral korteks hem de etkilenmiş, ya da sadece striatum olup olmayacağı çevirmek olacaktır. Hem enfarktüs ve reperfüzyon süreleri buna...

İnme bir kişi hastalıktan her 4 dakikada bir ölen ile, dünya çapında ölüm beşinci önde gelen nedenidir. 800.000 üzerinde Amerikalılar sadece hasta için yıkıcı olmayan bir felç, her yıl, acı, ama aynı zamanda aileleri için. İnme yetişkin sakatlık ana nedenidir ve yıllık harcama mevcut olan çok az tedavi seçenekleri olmasına rağmen 36500000000 $ 1 düzeyinde olduğu tahmin edilmektedir. Doku plazminojen aktivatörü (tPA) Sadece Gıda ve İlaç Dairesi (FDA) iskemik inme için ilaç lisanslı. Inme 3-6 saat içinde hastaya uygulandığı ve bu gibi durumlarda bu hastaların 2% 4 yarar Ancak, bu geçerlidir. Nedenle, inme, tekrar üretilebilir, klinik olarak hayvan modelleri, bu hastalık için potansiyel bir terapötik strateji ve tedavilerin geliştirilmesine yardımcı olmak için kullanılır zorunludur. In vitro dikkat etmek önemlidir </em&gt; modelleri, serebral disfonksiyon bazı yönlerini modelleme yararlı iken, bir inme sonrası beyin ve çevrede meydana gelen karmaşık fizyolojik etkileşimleri yansıtan yeteneğine sahip değildir. Sonuç olarak, in vivo modeller gereklidir. inme en yaygın türü, toplam inmelerin% 87 için muhasebe, menşe iskemik olduğunu. Diğer vuruş intraserebral kanama (% 9) ve subaraknoid kanama (% 4), ve orta serebral arter (MCA) bir emboli en sık neden olur. Bu kesintiye hale beyin giren laminer kan akımının neden MCA kökünde belirgin eğri, atfedilebilir. MCA yanal sulkus boyunca internal karotis arter (ICA) ve yolları, doğar nerede dalları ve projeler bazal ganglionlar ve frontal, parietal ve primer motor ve duyusal korteks olmak üzere temporal lob, yanal yüzeyler. Willis Çember olma posterior serebral arterlerin tarafından oluşturulanserebral arter ve posterior iletişim arterlere bağlı. MCAO intraluminal filament veya dikiş modeli en yaygın inme araştırmalarında kullanılan biridir. Ancak, bu modele farklı varyasyonlar bir çift vardır ve bu microfilament dış karotid arter içine takılı olup olmadığını dayalı 3 (ECA, Longa yöntemi olarak adlandırılır), ya da (ICA takılı olup olmadığını Koizumi olarak adlandırılır yöntemi) 4. Filament CCA içinde kesi kanamayı önlemek için kaldırılırsa Longa yönteminde kalıcı 5 bağlanmalıdır ECA ise Koizumi yöntemde, ameliyat tarafındaki karotis arter (CCA) kalıcı olarak bağlanmalıdır . Bu çok daha üstün ve iskemik inme bir daha klinik olarak cerrahi model hissediyorum burada Longa yöntemi kullanılacaktır. Bundan başka, özellikle Longa yöntemi ile bir silikon uçlu monofilin kullanımı, çok üretirgenellikle eksik tıkanıklığı ve / veya subaraknoid kanama 6 üretmek alev körelmiş monoipliklerin, aksine tekrarlanabilir MCAO. Intraluminal filament yöntemi kalıcı veya geçici tıkanma 4,6 modeli olarak kullanılabilir. Geçici modeli gerçekleştirmek için, filament iskemi bir süre sonra çıkartılır (örneğin, 30 dakika, 60 dakika ya da 2 saat) ve reperfüzyon meydana bırakılır. Bu model, bir ölçüde, insanlarda bir tromboembolik pıhtı eritmek için kendiliğinden ya da terapötik müdahale (örneğin, tPA uygulama) sonrasında kan akımının restorasyon simüle eder. Sürekli modeller için, filament, sadece bir zaman süresi (örneğin, 24 saat) yerinde kalır, bu nedenle bir reperfüzyon oluşur. lümen içi filament yöntemin diğer bir avantajı, bir kranyotomi kafatası sağlam kalmasına olanak sağlayan ve intrakranyal basınç ve sıcaklık değişiklikleri önlemek gerçekleştirilebilir gerekmez gerçektir. <p cBu videoda lass = &quot;jove_content&quot;&gt; biz MCAO ve reperfüzyon ikna etmek Longa intraluminal filament yöntemi gerçekleştirmek için nasıl gösterilmektedir. Biz de 18 sayılık nörolojik skoru gerçekleştirmek ve 2,3,5-triphenyltetrazalium klorür (TTC) boyama kullanarak infarkt hacmini belirlemek için nasıl gösterir.

surgical approach for middle cerebral artery occlusion and reperfusion induced stroke in mice

İnme, tüm dünyada ölüm önde gelen nedenidir ve uzun vadeli yetişkin engelli temel nedenlerinden biri olmaya devam etmektedir. vuruşları yaklaşık% 87 iskemik orijinlidir ve orta serebral arter (MCA) topraklarında meydana gelir. Şu anda sadece Gıda ve İlaç Dairesi (FDA) bu yıkıcı hastalığın tedavisi için ilaç onayladı doku plazminojen aktivatörü (tPA) &#39;dir. Bununla birlikte, tPA uygulama için küçük bir terapötik penceresi olan (3-6 saat) ve aslında uygulanan hastaların% 4 etkilidir. Mevcut araştırma potansiyel terapötik hedefleri bulmak için inme patofizyolojisinin anlaşılmasında odaklanır. Böylece, güvenilir modeller çok önemlidir ve MCA oklüzyonu (MCAO) modeli iskemik inme klinik olarak en uygun cerrahi modeli olarak kabul edilir (ayrıca lümen Filament veya sütür modeli olarak adlandırılan) ve oldukça non-invaziv ve kolay tekrarlanabilir. Genellikle MCAO modeli nedeniyle özellikle fare ile, kemirgenler kullanılırBu türler için mevcut tüm genetik varyasyonları. Burada tarif (ve video mevcut) başarıyla güvenilir ve tekrarlanabilir verileri oluşturmak için farelerde (reperfüzyon) ile MCAO modelini nasıl gerçekleştirileceği.

Fareler reperfüzyon süresi ardından 30 dakika MCAO-kaynaklı beyin iskemisi (Şekil 1) uygulandı (24 saat, 1 hafta, burada sunulan, ancak reperfüzyon uzunluğunun değiştirilmesi olabilir). MCAO sırasında ölüm (yaklaşık% 2) çok az oldu. Mesaj iskemi, (ilk 24 saat içinde) ölüm oranı yaklaşık% 26 idi. Lazer Doppler flowmetre öncesi ve MCAO / reperfüzyon sonrası MCA topraklarında kan akım?...
