Abstract

Objective: Aim of this study is to research the protective effect of pretreatment with statin (rosuvastatin) on erythrocyte membrane integrity after hindlimb ischemia reperfusion. Material and Method: Twenty adult male Wistar rats were divided into two groups. Ischemia reperfusion and statin pretreatment group as group I (n:10) and without treatment group II (n: 10). In Group I, rosuvastatin administered via oral gavage daily dose of 20mg/kg/day for 21 days. 5 cc saline solution was given to group II. After, 4 hours ischemia 4 hours reperfusion were performed on both groups on 22 nd day. Rats were sacrified at the end of reperfusion period and a 5 ml blood was withdrawn from ascending aorta for biochemical assays. Na+-K+ ATPase activity and the levels of serum malondialdehyde (MDA) for demonstrating erythrocyte membrane injury, serum LDH and AST levels for detecting hemolysis and additionally serum triacylglycerol (TAG), total cholesterol (TC), high-density lipoprotein-cholesterol (HDL-C), low-density lipoprotein-cholesterol (LDL-C) levels were measured for lipid metabolism. Results: Comparison between the groups were showed that serum MDA, LDL-C, TC and serum LDH and AST levels were found significantly low in group I. Membrane Na+-K+ ATPase activity and serum HDL-C levels were found high in group I. Negative correlation was found between MDA levels and Na+-K+ ATPase activity in group I. Additionally, diminishing levels of serum MDA was showing togeth- erness with the diminishing levels of LDL-C. Conclusions: Pretreatment with the rosuvastatin shows protective effect on erythrocyte membrane integrity and therefore hemolysis after hindlimb ischemia reperfusion.

Özet

Amaç: Bu çalışmanın amacı, bacak iskemi reperfüzyonu sonrası eritrosit membran bütünlüğü üzerine statin (rosuvastatin) ile ön tedavinin koruyucu etkisini araştırmaktır. Gereç ve Yöntem: Yirmi erişkin erkek Wistar rat iki gruba ayrıldı. İskemi reperfüzyon ve statin ile ön tedavi yapılan grup I (n:10) olarak ve tedavi edilmeyen grup II (n:10) olarak kabul edildi. Grup I’de rosuvastatin, günde tek doz 20mg/kg/gün dozunda 21 gün orogastrik sonda yoluyla verildi. Gup II’de 5cc/gün salin solüsyonu orogastrik sonda ile verildi. 22. gün her iki gruba da 4 saat iskemi, 4 saat reperfüzyon gerçekleştirildi. Ratlar reperfüzyon periyodunun sonunda sakrifiye edilerek asendan aortadan biyokimyasal ölçümler için 5cc kan alındı. Eritrosit membran hasarını göstermek için Na+-K+ ATPase aktivitesi ve serum malondialdehyde (MDA) düzeyi, hemolizi göstermek için serum LDH ve AST düzeyleri, ek olarak lipid metabolizmasını değerlendirmek için serum triaçilgliserol (TAG), total kolesterol (TC), yüksek dansiteli lipoprotein kolesterol (HDL-C), düşük dansiteli lipoprotein kolesterol (LDL-C) düzeyleri ölçüldü. Bulgular: Gruplar karşılaştırıldığında, serum MDA, LDL-C, TC ve serum LDH ve AST düzeylerinin Grup I’de anlamlı olarak daha düşük olduğu görüldü. Membran Na+-K+ ATPase aktivitesi ve serum HDL-C düzeyleri, Grup I‘de daha yüksek bulundu. Grup I’de MDA ve Na+-K+ ATPase aktivitesi arasında negatif korelasyon bulundu. Ek olarak, serum MDA düzeylerindeki azalma, LDL-C düzeylerindeki azalma ile birliktelik gösteriyordu. Sonuç: Rosuvastatin ile ön tedavi, bacak iskemi reperfüzyon sonrası eritrosit membran bütünlüğü üzerine ve dolayısı ile hemolize karşı koruyucu etki göstermektedir.
