Abstract

Aim Oxidative and nitrosative stress are important in the pathogenesis of heart dysfunction aſter endotoxemia. Asymmetric dimethylarginine competitively inhibits nitric oxide production by displacing L-arginine. A link between asymmetric dimethylarginine and inflammation has been demonstrated recently in the prediction of cardiovascular events. Peroxynitrite is a reaction product formed by the interaction between nitric oxide and superoxide. Material and Methods In this study, the relationship between asymmetric dimethylarginine and L-arginine level and 3-nitrotyrosine, a stable product of peroxynitrite formation was investigated aſter endotoxemia (4 mg /kg at 6h). Measurement of asymmetric dimethylarginine and L-arginine were accomplished by high pressure liquid chromatography with fluorescent detector. 3-nitrotyrosine was quantified by high pressure liquid chromatography with electrochemical detector. Results Aſter administration of endotoxin asymmetric dimethylarginine and L-arginine levels did not change but 3-nitrotyrosine levels statistically significantly increased (p

Özet

Amaç Endotoksemi sonrası kalp disfonksiyonu patojenezinde oksidatif ve nitrozatif stres önemlidir. Asimetrik dimetilarjinin, arjininin yerine geçerek nitrik oksit üretimini yarışmalı olarak inhibe eder. Kardiyovasküler vakaları öngörmede asimetrik dimetilarjinin ve inflamasyon arasındaki bağlantı yakın zamanda gösterilmiştir. Peroksinitrit nitrik oksit ve süperoksit arasındaki etkileşimden oluşan bir reaksiyon ürünüdür. Gereç ve Yöntemler Bu çalışmada endotoksemi (4 mg/kg, 6 saatte) sonrasında asimetrik dimetilarjinin ve L-arjinin seviyeleri ve peroksinitrit oluşumunun stabil ürünü olan 3-nitrotirozin arasındaki ilişki araştırılmıştır. Asimetrik dimetilarjinin ve L-arjinin floresan dedektör, 3-nitrotirozin ise elektrokimyasal dedektörlü yüksek basınçlı sıvı kromatografisi ile ölçülmüştür. Bulgular Endotoksin verildikten sonra asimetrik dimetilarjinin ve L-arjinin seviyelerinde değişiklik olmadı ama 3-nitrotirozin seviyeleri istatiksel olarak anlamlı derecede (p
