Bu yöntem beynin içine çok hassas yerlere ilaçlar veya viral vektörlerin en sunmak için çok yararlı olan bu video gösterdi. Bu tekniğin başlıca avantajlarından bazıları hedefleme nokta enjeksiyonları doğruluğu ve beyin lezyon ve sistem zarar 1, 2, 5, 6 küçük boyutlu güvenilirliğini. Sonra teknik mistargeting aralığında standardize 50 mm veya 1, 2 daha az. Hücre nakli aynı zamanda daha geniş, 100-150 mikron 7-9, iğneler kullanılarak yapılabilir. Bu nedenle ...

targeting of deep brain structures with microinjections for delivery of drugs, viral vectors, or cell transplants

Beyin parankimi içine Microinjections ilaçlar, viral vektörlerin veya hücre nakli sunmak için önemli prosedürler vardır. Bir enjeksiyon iğnesi, yörünge sırasında ürettiği beyin lezyonu sadece beyin küçük ama aynı zamanda bazen çoklu enjeksiyon ihtiyaç vardır özellikle fare beyinde önemli bir husustur. Biz burada cam kılcal iğneler beyin hasarı önemli ölçüde azaltır ve kemirgen beyin içine hassas bir hedefleme sağlar 50 mikron lümen üretmek için bir yöntem gösteriyor. Bu yöntem, küçük hacimli bir teslimat (20 100 nl), kanama riskini azaltır sağlar ve beyin parankimi içine ilaç pasif difüzyon en aza indirir. Farklı boyutta kılcal cam tüpler kullanarak veya iğne lümen değişen, çeşitli madde ve hücreler enjekte edilebilir. Cam kapiller tüp ile Microinjections enjeksiyon teknikleri ve küçük kemirgenler minimum teminat hasar hedefleyen derin beyin önemli bir iyileşme temsil eder.
