Abstract (2. Language): 
In chronic renal insufficiency, many toxic metabolites which are normally nontoxic but become toxic when combined improving oxidative metabolism, accumulates in the body fluids. We studied the effect of the most frequently used cuprophan and polysulfone dialysers in hemodialysis treatment on oxidant/ antioxidant status. For this purpose, 26 cases (9 females, 17 males, mean age of 36) that are used cuprophan dialysers (n=15) and polysulfone dialysers (n=11) were examined. The cases with COPD, DM and the ones using vitamin E and C, were excluded. First the plasma and red blood cells of the venous blood taken before and after hemodialyses were separated and than plasma MDA and intraerythrocyter GSH levels, activities of GSH-Px and SOD were measured. Results.- When the groups that are used cuprophan and polisulfone dialysers are compared; It is observed that the cuprophan dialysers increased plasma MDA levels (p<0,05), decreased the intraerythrocyter GSH levels (p<0,01), activities of GSH-Px (p<0,05) and SOD (p<0,05), as polisulfone dialysers did not influence the MDA and GSH levels, activities of GSH-Px and SOD (p>0,05). Conclusion.- Hemodialysis treatment is an oxidant stress for the organism and some of used dialysers is effective on this oxidant stress. As a conclusion, this is important in developing new membranes to control the production of free oxygen radicals.

Abstract (Original Language): 
KRY’li hastaların oksidan stres altında olduğu bilinmektedir. Cuprophan ve polisülfon dializörlerinin organizmanın oksidan sistemi ve antioksidan savunması üzerine ne gibi etkileri olduğunu saptamak amacıyla bu çalışmayı planladık. Çalışma Haydarpaşa Numune Hastanesi Hemodializ ünitesi ve özel bir merkez tarafından takip edilen 26 hasta üzerinde yapılmıştır. Hastaların 15’i Cuprophan dializörü, 11’i ise Polisülfon dializörü ile hemodialize girmiştir. Araştırma projemize göre, hastalardan hemodializ öncesi ve hemodializ sonrası, Cubital venden heparinli tüpe 10 ml kan alınmış, kan örnekleri hemen 3000 rpm de 5 dakika santrif üje edilerek plazma ve eritrositlerine ayrılmıştır ve plazma MDA düzeyleri ile, eritrosit içi SOD, GSH-Px enzim aktiviteleri ve GSH düzeyleri ölçülmüştür. Bulgularımıza göre MDA düzeyi hemodializ sonrası istatistiksel olarak anlamlı düzeyde yüksek bulundu (p<0,023). Hemodializ sonrasında, eritrosit-içi SOD ve GSH-Px aktivitesi ile GSH düzeyleri, istatistiksel olarak anlamlı düzeyde azalmış (sırasıyla p<0,018, p<0,026, p<0,007) olarak belirlendi. Cupro-phanla yapılan hemodializ sonrasında MDA düzeyleri artmakta (p<0,037), eritrosit-içi SOD ve GSH-Px aktivitesi ile GSH düzeyleri ise, anlamlı olarak (sırasıyla p<0,032, p<0,05, p<0,007) azalmaktadır. Polisülfonla yapılan hemodializde, saptanan parametreler açısından giriş ile çıkış arasında istatistiksel olarak anlamlılık saptanmamıştır (p>0,05). Sonuç olarak, hemodializin oksidan stresi artırdığı, eritrosit içi (hücre içi) antioksidan enzimlerin aktivitesini azalttığı, Cuprophan dializörünün oksidan stresi artırdığı, antioksidan enzimlerin aktivitesini azalttığı, Polisülfon hemodia- CERRAHPAŞA T 80 IP DERGİSİ Cilt (Sayı) 31 (2) lizörünün oksidan/antioksidan dengeye etkisi olmadığı saptandı. Yeni membranlar geliştirilirken, oksijen radikal üretimi açısından kontrol edilmesinin çok ö- nemli olduğu vurgulandı.
