Abstract

Objectives: In this study, we investigated the antioxidant protective effects of melatonin on skeletal muscles of Wistar albino-type rats with acute ischemia/reperfusion (I/R) injury. Materials and methods: Twenty-eight Wistar albino-type male rats weighing between 334 to 422 g were included in this experimental study. The rats were randomly allocated into three groups including sham, I/R and I/R + melatonin groups, respectively. Limb ischemia was achieved by clamping femoral arteries. After a two-hour ischemia period followed by 1.5- hour reperfusion, muscle samples were collected for biochemical analysis and histopathological examination. Results: Muscle tissues of I/R groups revealed significantly higher antioxidant enzyme (superoxide dismutase, glutathione peroxidase, catalase) activities, and increased levels of malondialdehyde, nitric oxide, and protein carbonyl content compared to the control group (p

Özet

Amaç: Bu çalışmada, akut iskemi/reperfüzyon (İ/R) yaralanması oluşturulan Wistar albino türü sıçanların iskelet kasları üzerinde melatoninin antioksidan koruyucu etkisi araştırıldı. Gereç ve yöntemler: Bu deneysel çalışmaya ağırlıkları 334-422 g arasında olan 28 erkek Wistar albino türü sıçan alındı. Sıçanlar, randomize olarak sırasıyla, kontrol, İ/R ve İ/R + melatonin olmak üzere üç gruba ayrıldı. Ekstremite iskemisi, femoral artere klemp konarak sağlandı. İki saat iskemi süresini takiben 1.5 saat süren reperfüzyon sonrasında, biyokimyasal analiz ve histopatolojik inceleme için kas örnekleri alındı. Bulgular: İskemi/reperfüzyon grubunun kas doku örneklerinde antioksidan enzim (süperoksit dismutaz, glutatyon peroksidaz, katalaz) aktiviteleri, malondialdehit, nitrik oksit düzeyleri ve protein karbonil içeriği kontrol grubuna göre anlamlı derecede yüksek bulundu (p
