Vasogenic Beyin ödemi kan - beyin bariyerini (BBB) bozulma nedeniyle iskemik inme önemli bir komplikasyonu ve inme hasta1,2sağkalım oranı önemli bir belirleyici kalır. Kan - beyin beyin kapiller endotel hücreleri tarafından (BCECs) kurdu ve farklı nörovasküler bileşenler (Örneğin, BCECs, perisitlerden, astroglial ve nöronal hücrelerin3arasında sıkı kavşak) oluşur, bariyerini (BBB), sağlar bir Merkezi sinir sistemi (MSS) ve periferik dolaşım4,5arasında uzman ve dinamik arabirim. İskemi-reperfüzyon yaralanmalar gibi hakaret BBB işlevsel bütünlüğü bozabilir ve lökosit sonuçta beyin iltihabı ve birincil beyin yaralanmaları tetiklemek beyin parankimi dolaşan sonraki penetrasyon yol 6 , 7. hayvan modelleri felç oluşumunu takip BBB disfonksiyon kesin tespiti için ihtiyaç vardır.

an in vivo assessment of blood-brain barrier disruption in a rat model of ischemic stroke

İskemik inme vasogenic serebral ödem ve kan - beyin bariyerini (BBB) imha aracılık ettiği sonraki birincil beyin hasarı yol açar. Fareler indüklenen iskemik inme ile kurulan ve in vivo modelleri BBB işlevsel bütünlüğü araştırmak için kullanılan. Evans mavi (EB) spektrofotometrik algılama beyin örneklerinde iskemik yaralanma ile araştırma ve geliştirme yeni tedavi yöntemleri için güvenilir gerekçe sağlayabilir. Bu yöntem tekrarlanabilir sonuçlar üretir ve özel ekipman gerek olmadan herhangi bir laboratuvar geçerlidir. Burada, indüksiyon Sıçanlarda iskemik inme takip EB ekstravazasyonu algılamayı görüntülenmeyecektir ve teknik kılavuz mevcut.

Karşı sahte ile çalışan fareler sol hemisfer sağ hemisfer EB düzeylerinde anlamlı bir fark yoktu (1.06 ± 0,1 µg/g ve 1,1 ± 0,09 µg/g, sırasıyla). Rakamlar 2A-2B, indüksiyon geçici iskemi gösterildiği gibi (90 dk iskemi / 24 h reperfüzyon) EB seviyesi önemli bir fark neden (10.41 ± 0,84 µg/g, p < 0.001) ile karşılaştırıldığında ilgili iskemik sıçan sol yarıküre'deki sham çalışan fareler yarımkürede. Toplu olarak, bu bulgular ...
