Abstract

Objective: This study aimed to investigate the vasorelaxation effect ofnebivolol on vasospasm in the rabbit model of subarachnoid hemorrhage(SAH).Method: Single-hemorrhage model in the rabbit SAH was employed.SAH was induced in animals by cisterna manga injection of 4 mLautologous blood. Thirty-two animals were categorized into four groups:1) control group (no SAH), 2) SAH group, 3) SAH + solvent infused groupand 4) SAH + nebivolol treatment group. Forty-eight hours after SAHinduction, rabbits in group 3 and in 4 were received solvent or nebivolol,respectively. Nebivolol (0.073 mg/kg) was administered via the vertebralartery in 5 minutes. Digital subtraction angiography was performed atforty-nine hour following SAH-induced groups. The diameters of basilararteries in four groups were measured at three points, and the average ofthe measurements was accepted as a consecutive result.Results: SAH-induced rats demonstrated severe vasospasm on day 2.Angiographic vasospasm was present in group 2 (SAH only), and in 3(SAH plus solvent). Animals in group 4 (SAH plus nebivolol) and group1 (control), respectively, demonstrated the largest diameters of basilararteries. Animals treated with nebivolol has reached eighty-eight percentof the value in the control group 1. There was no statistical differencebetween the control group and SAH plus nebivolol treatment group(p>0.05). However, the difference was obtained between the groups SAHplus solvent and SAH plus nebivolol treatment (p

Özet

Amaç: Günümüzde, subraknoid kanama (SAK) sonrası ortaya çıkan vazospazm halen etkin olarak tedavi edilememektedir. β-1 reseptör antagonisti olan nebivololün, deneysel ve klinik araştırmalarda vazodilatasyon etkisi kanıtlanmıştır. Bu çalışmada, nebivololün SAK sonrası gelişen deneysel vazospazmın tedavisindeki etkinliği araştırılmıştır. Yöntem: Çalışmada, 32 adet Yeni Zelanda türü tavşan eşit olarak 4 gruba ayrıldı: 1) Kontrol grubu, 2) SAK grubu, 3) SAK + solvent verilen grup ve 4) SAK + nebivolol tedavi grubu. İkinci, 3. ve 4. gruptaki tavşanlarda tek kanamalı SAK modeli uygulandı. Tüm deneklere dijital anjiyografi yapıldı. Üçüncü ve 4. gruptaki tavşanlarda SAK sonrası 48. saatte transfemoral yöntemle Arteria vertebralis içine yerleştirilen kateterle 1 mL solvent (nebivololün içinde çözünmesinde kullanılan solüsyon) veya 1 mL hacim içinde 0.073 mg/kg dozda nebivolol infüzyonu yapıldı. SAH uygulanan 2., 3. ve 4. grup deneklere SAK uygulamasının 49. saatinde ve 1. gruptaki deneklere dijital anjiyografi yapıldı. Bulgular: Baziler arter ortalama çapları grup 1’de 0,64 mm, grup 2’de 0,33 mm, grup 3’te 0,37 mm ve grup 4’te 0,56 mm olarak saptandı. İkinci gruptaki deneklerde SAK sonrası 48. saatte yapılan dijital anjiyografi incelemesinde ağır vazospazm geliştirdiği saptandı. Baziler arter çapları dikkate alındığında, istatistiksel olarak grup 1 ve 4 sonuçları arasında anlamlı fark saptanmadı (p>0,05). Üçüncü grupta solvent verilen deneklerde ağır vazospazm oluşumu saptanmasına ragmen, dördüncü grupta nebivololün SAK’ye bağlı vazospazm gelişimini etkin olarak tedavi ettiği saptandı (p
