Oreochromis niloticus ’un Farklı Dokularında SOD Aktivitesi Üzerine Kadmiyumun Etkisi

Bu çalışmada kadmiyum’un Oreochromis niloticus’da superoksit dismutaz (SOD) aktivitesi üzerine etkileri araştırılmıştır. Balıklar 0.2, 1.0 ve 2.0 mg/L Cd derişimlerinin etkisine 15 ve 30 günlük sürelerle bırakılarak karaciğer, solungaç, böbrek ve kas dokularında superoksit dismutaz (SOD) aktiviteleri belirlenmiştir. Kadmiyumun farklı derişimlerinin etkisine bırakılan O. niloticus'un karaciğer, böbrek, solungaç ve kas dokularında süperoksit dismutaz (SOD) enzim aktivitesi kontrol değerleriyle ile karşılaştırıldığında önemli değişiklikler belirlenmiştir. Kadmiyumun denenen yüksek derişimleri karaciğer dokusunda süperoksit dismutaz (SOD) aktivitesinin azalmasına, böbrek dokusunda ise bir artışa neden olmuştur.

Effect of Cadmium on SOD Activity in different Tissues of Oreochromis niloticus

In this study, the effects of cadmium on the superoksit dismutaz (SOD) activity in Oreochromis niloticus were investigated. Fishes were exposed to 0.2, 1.0 ve 2.0 mg/L Cd for 15 and 30 days to determine superoksit dismutaz (SOD) activities in liver, gill, kidney and muscle tissues. The were significant changes in superoksit dismutaz (SOD) activities in liver, gill, kidney and muscle tissues of O. niloticus exposed to cadmium compared to controls. At the high concentrations tested, cadmium caused a decrease in superoksit dismutaz (SOD) activity in the liver while it caused an increase in the kidney tissue.
