Abstract

In the present study, oxidative system status both in plasma and renal tissue of rats with adriamycin induced experimental rat nephrotic syndrome was investigated. Glutathion peroxidase (GSH-Px) activities and malondialdehyde (MDA) levels in plasma and MDA levels, GSH-Px and superoxide dismutase (SOD) activities in kidney homogenates were determined. Plasma MDA levels and tissue SOD activities were significantly higher in nephrotic rats when compared to those of the controls. No correlation was found between plasma and tissue MDA levels while plasma MDA levels of nephrotic rats had positively significant correlations with urinary protein excretion and serum total cholesterol levels. Serum albumin levels showed negatively significant correlations with plasma MDA levels in nephrotic rats. The data suggest that increased oxidative stress in renal tissue seem not to be responsible principally for high plasma MDA levels observed in rats with nephrotic syndrome. Nephrotic state has significant contributions to elevated plasma MDA levels and severity of nephrotic syndrome is related to the high levels of plasma MDA.

Özet

Bu çalışmada, adriamisin ile oluşturulan deneysel sıçan nefrotik sendromunda plazma ve böbrek dokusunda oksidatif sistemin durumu araştırılmıştır. Plazma glutatiyon peroksidaz (GSH-Px) aktivitesi ve malondialdehit (MDA) düzeyleri ile, böbrek homojenatları nda MDA düzeyleri, GSH-Px ve süperoksit dizmutaz (SOD) aktiviteleri çalışılmıştır. Plazma MDA düzeyleri ve doku SOD aktiviteleri kontroller ile karşılaştırıldığında nefrotik sıçanlarda belirgin olarak daha yüksektir. Doku ve plazma MDA düzeyleri arasında belirgin bir ilişki saptanamazken, nefrotik sıçanlarda üriner protein atılımı ve serum total kolesterol düzeyleri ile plazma MDA düzeyleri belirgin bir pozitif korelasyon içindedir. Nefrotik sıçanlarda serum albumin düzeyleri plazma MDA düzeyleri ile belirgin negatif korelasyon göstermiştir. Bu bulgular, nefrotik sendromlu sıçanlarda saptanan yüksek MDA düzeylerinin esas sorumlusunun artmış renal doku oksidatif stresi olmadığını göstermektedir. Nefrotik durum yüksek plazma MDA düzeylerine belirgin olarak etki ederken, nefrotik sendromun ağırlığı ile plazma MDA düzeylerinin yüksekliği ilişkilidir
