Stroke continues to be an enormous burden for patients and clinicians. Animal stroke models have been used in the laboratory setting for nearly two decades.1 Nevertheless, experimental treatments that work in animals often fail in humans.2 This discrepancy in treatment outcomes may be due to various factors, such as administration routes for drugs used in animal research, drug metabolism and elimination rate, and many other aspects. One of the major complications of stroke, brain edema, is a focus of current research in neuroscience. Mechanisms of brain edema formation involve disturbances in water and electrolyte balance triggered by the arginine-vasopressin (AVP) response to ischemic brain injury.3 Therefore, AVP and its receptors (V1a and V2) are a major focus of research studies of post-ischemic brain edema formation.3
We have developed a methodology to study the effects of mixed arginine-vasopressin (V1a and V2) receptor blocker conivaptan on post-ischemic brain edema in mice.4 Molecular targets of conivaptan5 make the drug a suitable candidate for exploration of its properties in alleviation of brain edema. Furthermore, conivaptan needs to be studied in the context of pathophysiological events of stroke.6 In designing this study, we considered comparing treatment outcomes using two different routes of administration for conivaptan: intravenous (IV)4 and intraperitoneal (IP).7 Effects of the treatments on stroke-induced brain edema were evaluated. Here detailed protocols are described for surgical induction of experimental stroke by middle cerebral artery occlusion (MCAO), and followed by continuous conivaptan treatment using the installation of a jugular IV catheter. After induction of stroke, animals were randomly allocated into the following groups: vehicle or conivaptan (0.2 mg/day) treated IV or IP.

continuous iv infusion is the choice treatment route for arginine-vasopressin receptor blocker conivaptan in mice to study stroke-evoked brain edema

İnme, dünyada morbidite ve mortalitenin en önemli nedenlerinden biridir. İnme, beyin ödemi ve diğer patofizyolojik olaylar nedeniyle karmaşıklaşır. inme-uyarılmış beyin ödemi gelişmesi ve evriminde en önemli oyuncuları arasında hormon arjinin-vasopresin ve reseptörleri, V1a ve V2 olduğunu. Son zamanlarda, V1a ve V2 reseptör blokeri Conivaptan inme sonrası beyin ödemi azaltmak için potansiyel bir ilaç olarak dikkat çekmektedir. Bununla birlikte, vuruş araştırma Conivaptan uygulamaları dahil hayvan modelleri uygulama uygun yolları göre değiştirilmesi gerekir. Burada 48 saat sürekli intravenöz (IV) &#39;sonuçları farelerde deneysel inme sonrası intraperitoneal (İP) Conivaptan tedavileri ile karşılaştırılmıştır. Bu orta serebral arter oklüzyonu Conivaptan (0.2 mg) veya aracın IV tedavisi için boyun damarına sonda yükleme ile kombine edildiği bir protokol geliştirilmiştir. Hayvanların Farklı Gruplar 0.2 ile muamele edilmiştirGünlük Conivaptan veya aracına IP mg bolus. Deneysel inme uyarılmış beyin ödemi, sürekli IV ve IP tedavilerden sonra farelerde değerlendirildi. sonuçların karşılaştırılması Conivaptan Sürekli infüzyon tedavisi Conivaptan IP uygulamasının farklı olarak, farelerde post-iskemik beyin ödemi azaltır olduğunu ortaya koymuştur. Bizim modeli inme ve beyin ödemi bağlamında Conivaptan uygulamaların gelecekteki çalışmalar için kullanılabileceğini düşünmekteyiz.
