Sempatik sinir sistemi ve düşük kardiyak vagus aşırı aktivite yüksek kan basıncı (tansiyon)1olarak katkıda bulunur. Kronik olarak yükseltilmiş böbrek sempatik çıkış katekoiamin salgılanmasını artırır ve kalp-damar/böbrek sistemleri2,3zararlı sonuçları ile renal kan akımı azalır.

quantifying acute changes in renal sympathetic nerve activity in response to central nervous system manipulations in anesthetized rats

Böbrek sempatik sinir etkinliği (RSNA) ve ortalama arteriyel basınç kardiyovasküler ve otonomik araştırmada önemli parametreler şunlardır; Ancak, sınırlı kaynakları bilim adamları ölçme ve bu değişkenlerin analiz teknikleri yönetmenlik vardır. Bu iletişim kuralı RSNA ve imzalat sıçanlarda ortalama arter basıncı ölçüm yöntemlerini açıklar. Protokolü de merkezi sinir sistemi (MSS) manipülasyon için RSNA kayıtlar sırasında beyin erişmek için yaklaşımları içerir. RSNA kayıt tekniği ile uyumludur farmakolojik, optogenetic, veya MSS elektrik stimülasyon. Bir dedektif kısa vadeli (min h) otonomik yanıt anatomik olarak CNS çekirdeği ile ilişkilendirmek için hayatta kalma sigara deneylerde ölçtüğünüzde yararlı bir yaklaşımdır. Yaklaşım içinde rats RSNA kronik (hayatta kalma) kayıtları elde etmek için kullanılmak üzere tasarlanmamıştır. RSNA, ortalama deşarj RSNA doğrultucu ve ortalama arteriyel basınç olabilir sayılabilir ve daha fazla parametrik istatistik testleri kullanılarak analiz. Venöz erişim, ortalama arteriyel basınç telemetrically kayıt ve beyin fiksasyon gelecekteki histolojik analizler için edinme yöntemleri de makalesinde açıklanmıştır.

Şekil 1 bir örnek RSNA ve BP kaydından tedavisiydi anestezi sıçan göstermektedir. Phenylephrine bir İntravenöz enjeksiyon ortalama arteriyel basınç artışı teşvik ve baroreflex ve geçici sympathoinhibition4,6uyandırmak için kullanıldı. RSNA ölçmek için ham RSNA doğrultucu ve üst üste 10 s segmentler için Ortalama olarak; gürültü tahmin her kesiminden düşülen.

Quantifying Acute Changes in Renal Sympathetic Nerve Activity in Response to Central Nervous System Manipulations in Anesthetized Rats

Yanıt Merkezi sinir sistemi manipülasyonlar imzalat Sıçanlarda Böbrek sempatik sinir faaliyette akut değişiklikler miktarının

Sempatik ve kardiyovasküler Yanıt Merkezi sinir sistemi (MSS) manipülasyonlar ölçme yöntemleri ilerleyen nörolojik için önemlidir. Bu iletişim kuralı ile ölçme ve böbrek sempatik sinir etkinliği (RSNA) (hayatta kalma olmayan) imzalat sıçanlarda akut değişiklikler miktarının bilim adamları yardımcı olmak için geliştirilmiştir.

Renal sympathetic nerve activity (RSNA) and mean arterial pressure are important parameters in cardiovascular and autonomic research; however, there are ...
