Abstract

Objectives: We aimed to investigate the effects of leptin on wound tissue malondialdehyde and reduced glutathione levels in Streptozotocin-induced diabetic and healthy rats.Patients and Methods: Experiments were performed on 28 male Wistar rats. Animals were divided as healthy control (n = 14) and Streptozotocin -induced diabetic (n = 14) rats. Diabetes was induced by injection of Streptozotocin (intraperitoneally, 55 mg/kg bw). On the 7th day after administration of Streptozotocin, six full-thickness excisional wounds were made under anesthesia in all animals. Then, both healthy and diabetic animals were divided into systemic leptin (intraperitoneally; 0.1mg/kg/day, for 5 days) and vehicle (Phosphate buffered saline (PBS)) subgroups. For topical administrations, wounds of all rats were covered with 5 µg leptin (in 20 µl PBS, for 5 days- right side wounds) and vehicle (left side wounds). At the end of these administrations, the animals were sacrificed and MDA and GSH analysis were made on wound tissues.Results: High MDA and low GSH levels were observed in diabetic control wounds than in healthy control wounds. Topical treatment of normal wounds and systemic and topical co- treatment of diabetic wounds with leptin decreased malondialdehyde levels of wound tissue.Conclusion: Wound tissue oxidative damage might diminish via leptin in healthy and diabetic rats.

Özet

Amaç: Streptozotosin ile diyabet oluşturulmuş ve sağlıklı sıçanlarda Leptin uygulamasının yara dokularında malondialdehit ve redükte glutatyon düzeylerine etkisini araştırmak amaçlanmıştır.Gereç ve Yöntem: Çalışmada 28 adet Wistar albino erkek sıçan kullanıldı. Sıçanlar sağlıklı kontrol (n=14) ve Streptozotosin-diyabetik (n=14) olarak iki ana gruba ayrıldı. Diyabet Streptozotosin uygulaması (intraperitoneal, 55 mg/kg) ile oluşturuldu. Kontrol grubuna eş hacimde Sitrat tampon enjekte edildi. Streptozotosin uygulamasından 7 gün sonra tüm sıçanlarda, anestezi altında iken sırtta orta hattın iki yanında 6 adet eksizyonel cilt yarası oluşturuldu. Sağlıklı ve diyabetik sıçanlar leptin ve taşıyıcı alt gruplarına ayrıldı. Beş gün süre ile leptin gruplarına sistemik olarak leptin (intraperitoneal; 0.1mg/kg/gün), taşıyıcı gruplarına ise eş hacimde fosfat tampon (PBS) ve tüm sıçanlarda sırtta orta hattın sağındaki yaralarına 5 µg leptin (20 µl PBS içinde), solundaki yaralarına eş hacimde PBS uygulandı. Uygulamaların sonunda anestezi altında feda edilen sıçanların yara dokularında MDA ve GSH ölçümleri yapıldı.Bulgular: Diyabetik kontrol yaraları sağlıklı kontrol yaraları ile karşılaştırıldığında MDA düzeyleri anlamlı olarak yüksek, GSH düzeyleri anlamlı olarak düşük bulundu. Leptin; sağlıklı sıçanlarda topikal olarak uygulandığında, diyabetik sıçanlarda ise topikal ve sistemik birlikte uygulandığında yara dokusu MDA düzeylerinin kontrol yaralarına göre anlamlı düzeyde düşürdü.Sonuç: Sağlıklı ve diyabetik sıçanlarda leptin uygulaması ile yara dokusundaki oksidan hasar azaltılabilmektedir.
