⚡ TL;DR(Too Long; Didn't Read)

Since many toxicologie substances are being metabolised through the free radical pathway, we aimed to establish antioxidant systems in mice (Mus musculus) and fish (Oreochromis niloticus) that had normal livers according to the results of histopathological analysis.

📌 3 Key Takeaways

🎯
Objective & Hypothesis:Purpose: Free oxygen radicals produced during the normal metabolism cause damage.
📊
Key Findings & Data:This possible damage is prevented by the cellular antioxidant system which consists of Glucose-6-phosphate dehydrogenase (G6PD), glutathione reductase(GR), superoxide dismutase (SOD) and glutathione (GSH).
💡
Conclusion & Impact:Since many toxicologie substances are being metabolised through the free radical pathway, we aimed to establish antioxidant systems in mice (Mus musculus) and fish (Oreochromis niloticus) that had normal livers according to the results of histopathological analysis.

Abstract

Purpose: Free oxygen radicals produced during the normal metabolism cause damage. This possible damage is prevented by the cellular antioxidant system which consists of Glucose-6-phosphate dehydrogenase (G6PD), glutathione reductase(GR), superoxide dismutase (SOD) and glutathione (GSH). Since many toxicologie substances are being metabolised through the free radical pathway, we aimed to establish antioxidant systems in mice (Mus musculus) and fish (Oreochromis niloticus) that had normal livers according to the results of histopathological analysis. Material and Methods: Glucose-6-phosphate dehydrogenase (G6PD) activity was measured by Bentler method, glutathione reductase (GR) by Staal method, superoxide dismutase (SOD) by Fridovich method and reduced glutathione (GSH) by Bentler method in the liver tissues of the above species. Results: The levels of the enzymes and reduced gluthatione were; G6PD: 2.38±1.09 U/g liver (M.musculus), 21.88±6.95 U/g liver (O. niloticus); GR: 2.47±1.31 U/g liver (M.musculus), 1.01±0.26 U/g liver (O. niloticus); SOD: 553.71±214.26 U/g liver (M.musculus), 388.10±459.40 U/g liver (O. niloticus); GSH: 0.946±0.228 umol/g liver (M.musculus), 0.123±0.035 umol/g liver (O. niloticus). Conclusion: The G6PDH activity in O. niloticus was significantly higher than that found in M. musculus but GR, SOD activities and GSH level were significantly lower. Antioxidant systems showed significant differences within different strains and species (p

Özet

Amaç: Normal metabolizma süresince türeyen serbest oksijen radikalleri hücrede hasar olustururlar. Bu hasarı önleyecek mekanizma, hücresel antioksidan sistem olup Glukoz-6-fosfat dehidrogenaz(G6PD) glutatyon redüktaz (GR) süperoksit dismutaz (SOD) ve glutatyon (GSH) gibi maddelerdir. Birçok toksikolojik maddeler serbest oksijen radikalleri oluşturduğundan ileride yapılacak toksikolojik çalışmalara temel teşkil etmek üzere fare (Mus musculus) ve balık (Oreochromis niloticus) antioksidan sistemleri Karaciğer histopatolojisi değerlendirildi. Gereç ve Yöntem: Glukoz-6-fosfat dehidrogenaz aktivitesi (G6PD) Bentler metoduyla, glutatyon redüktaz (GR) Staal metoduyla, süperoksit dismutaz (SOD) Fridovich metoduyla ve redükte glutatyon (GSH) Bentler metoduyla bu iki türde karaciğer dokusunda belirlenmistir. Bulgular: G6PD: 2.38±J.09 Ü/g karaciğer (M.musculus), 21.88±6.95 Ü/g karaciğer (T.nilotica); GR: 2.47±1.31 Ü/g karaciğer (M.musculus), 1.01±0.26 Ü/g karaciğer (T.nilotica); SOD: 553.71±214.26 ü/g karaciğer (M.musculus), 388.10±459.40 Ü/g karaciğer (T.nilotica); GSH: 0.946±0.228 umol/g karaciğer (M.musculus), 0,123±0.035 umol/g karaciğer (T.nilotica) olarak bulunmuştur. Sonuç: O Niloticus 'da G6PDH aktivitesi M. musculusdan anlamlı dercede yüksek fakat GR, SOD aktivitesi ve GSH düzeyinin oldukça düşük olduğu gözlenmiştir.Antioltsidan sistemlerin tür içi ve türler arasında önemli farklılıklar gösterdiği saptanmıştır (p
