contrast ultrasound targeted treatment of gliomas in mice via drug-bearing nanoparticle delivery and microvascular ablation

Biz permeabilization ve / veya ultrason darbeli parametreleri değişen mikrodolaşımını ablasyonu kontrol edilen minimal invaziv kontrast madde mikrokabarcık tabanlı terapötik yaklaşımlar geliştirmektedir. Özellikle, bu tür yaklaşımlar, ilaç dağıtım ve mikrovasküler ablasyon ile kötü huylu beyin tümörleri tedavi etmek için kullanılabilir olup olmadığını test. 100nm poli (lactide-co-glycolide) (PLAGA) albümin kabuklu mikro kabarcık yapıştırılır nanopartiküller oluşan &quot;kompozit&quot; teslim ajanların ultrason aracılı tahrip edilmesi hedeflenen ilaç taşıyan nanoparçacık teslim kolaylaştırılabilir olup olmadığını belirlemek için ön çalışmalar yapılmıştır . Bu ajanlar, mikrokabarcık nanoparçacık kompozit ajanlar (MNCAs) olarak ifade eder. Ultrason ile subkutan C6 gliomlar hedeflenmiş, mikro kabarcık nanoparçacıkların ve tedavi edilmeyen tümörler üzerinde 8.5 kat artış ile birlikte uygulandığında tedavi tümörleri üzerinde MNCA tedavi edilen tümörlere nanoparçacık teslim anında 4,6 katlık bir artış gözlemledik. Ayrıca, birçok kanser uygulamaları, hedeflenen ilaç, tümör hipoksi ve apoptosis yol açacaktır tümör mikrosirkülasyon, ablasyon ile birlikte teslim gerçekleştirmek için istenebilir inanıyoruz. Bu amaçla, biz, bu yaklaşım, tümör perfüzyon azalması, apoptozis, önemli bir büyüme inhibisyonu ve nekroz ortaya çıkarır olduğunu gösteren olmayan theramal kavitasyon bağlı mikrovasküler ablasyon etkinliğini test ettik. Birlikte ele alındığında, bu sonuçlar bizim ultrason hedefli bir yaklaşım mikrovasküler ablasyon ve / veya aynı anda gliomlar uyuşturucu yükü artırılması yoluyla tümör nekroz oluşturarak tedavi etkinliğini artırmak için bir potansiyele sahip olduğunu göstermektedir.
