Abstract

BACKGROUND: This study was designed to determine possible protective effect of betaine treatment against oxidative injury in pulmonary tissue induced with thermal trauma.METHODS: Under ether anesthesia, shaved dorsum of Wistar albino rats was exposed to a 90°C water bath for 10 seconds to induce burn injury. Betaine was administered orally (250 mg/kg) for a period of 21 days before burn injury, and single dose of betaine was administered after thermal injury. Control group rats were exposed to 25°C water bath for 10 seconds. Upon conclusion of experiment, rats were decapitated and blood was collected for analysis of pro-inflammatory cytokines and lactate dehydrogenase (LDH) activity. Lung tissue samples were taken to determine malondialdehyde (MDA) and glutathione (GSH) levels, myeloperoxidase (MPO), and Na+/K+-ATPase activity, in addition to histological analysis.RESULTS: Burn injury caused significant increase in both cytokine levels and LDH activity. In lung samples, raised MDA levels, MPO activity, and reduced GSH levels and Na+/K+-ATPase activity were found due to burn injury.CONCLUSION: Treatment of rats with betaine significantly restored GSH level and Na+/K+-ATPase activity, and decreased MDA level and MPO activity. According to the findings of the present study, betaine significantly diminishes burn-induced damage in tissue

Özet

AMAÇ: Bu çalışma, yanığa bağlı olarak gelişen akciğerdeki oksidatif hasara karşı betain tedavisinin olası koruyucu etkisini tanımlamak için tasarlandı. GEREÇ VE YÖNTEM: Yanık oluşturmak için sırt derileri traş edilmiş Wistar albino türü sıçanlar, eter anestezisi altında 10 saniye süreyle 90°C suya tutuldu. Yanık oluşturulmadan evvel 21 gün süre ile betain 250 mg/kg dozunda oral olarak uygulandı ve yanık oluşturulduktan sonra tek doz betain uygulaması yapıldı. Kontrol grubunda ise aynı işlem uygulandıktan sonra sırt bölgeleri 10 saniye süreyle 25°C suya tutuldu. Deney sonunda sıçanlar dekapite edildi ve kan numuneleri proinflamatuvar sitokinleri (tümör nekroz faktör- [TNF-] and interlökin 1 beta [IİL-1]) ve LDH aktivitesini analiz etmek için toplandı. Akciğer doku örnekleri histolojik analizlarin yanı sıra MDA ve GSH seviyelerini, MPO ve Na+, K+-ATPaz aktivitesini belirlemek için alındı.BULGULAR: Yanık hasarı sitokin seviyelerinde ve LDH aktivitesinde önemli derecede artışa neden oldu. Yanık hasarına bağlı olarak akciğer dokula-rında MDA seviyeleri ve MPO aktivitesi yüksek, GSH seviyeleri ile Na+, K+-ATPaz aktivitesi düşük bulundu.TARTIŞMA: Bu çalışmanın bulgularına göre yanığın serum ve dokuda neden olduğu hasarın betain ile anlamlı olarak azaldığı saptanmıştır.Anahtar sözcükler: Akciğer hasarı; betain; oksidatif stres; sitokinler; termal travma.
