Abstract

Background: This study aims to investigate the effects of blunt lungtrauma performed in experimental rat model on lung tissue and bloodas well as proinflammatory cytokines, oxidant-antioxidant enzymes andhistopathological parameters after Ngamma-nitro-L-arginine methylester and N-iminoethyl-L-ornithine administration.Methods: The study included 50 adult male Wistar albino rats (weighing350 to 400 g). Rats were randomly allocated into four groups. Exceptin the control, moderate-level pulmonary contusion was created in allother groups. Intraperitoneal saline solution was performed in groups 1and 2, 25 mg.kg-1 Ngamma-nitro-L-arginine methyl ester in group 3, and20 mg.kg-1 N-iminoethyl-L-ornithine in group 4. Blood and lung tissueswere studied biochemically and histopathologically.Results: Best outcomes were recorded statistically significantly in groupswith administration of Ngamma-nitro-L-arginine methyl ester andN-iminoethyl-L-ornithine when malondialdehyde response, mucous andhistopathological values were examined. Significant improvement wasdetected in superoxide dismutase values in the group with administrationof competitive nitric oxide synthase inhibitor Ngamma-nitro-L-argininemethyl ester. Nitric oxide values were substantially decreased inN-iminoethyl-L-ornithine group, while no significance was detected.Conclusion: Free oxygen radicals and lipid peroxidation played a role inpulmonary contusion after blunt lung trauma. According to biochemicaland histopathological outcomes, effects of inflammation were decreasedand protective effects were formed with administration of both Ngammanitro-L-arginine methyl ester and N-iminoethyl-L-ornithine.

Özet

Amaç: Bu çalışmada deneysel sıçan modeli üzerinde uygulanan künt akciğer travmasının akciğer dokusu ve kandaki etkileri ile Ngammanitro- L-arginin metil ester ve N-iminoetil-L-ornitin uygulamasını takiben proenflamatuvar sitokinler, oksidan-antioksidan enzimler ve histopatolojik parametreler araştırıldı. Çalışma planı: Çalışmaya 50 erişkin erkek Wistar albino sıçan (ağırlık 350-400 g) dahil edildi. Sıçanlar rastgele dört gruba ayrıldı. Kontrol dışındaki diğer tüm gruplarda orta şiddette pulmoner kontüzyon oluşturuldu. Grup 1 ve 2’ye intraperitoneal salin solüsyonu, grup 3’e 25 mg.kg-1 Ngamma-nitro-L-arginin metil ester, grup 4’e 20 mg.kg-1 N-iminoetil-L-ornitin uygulandı. Kan ve akciğer dokuları biyokimyasal ve histopatolojik açıdan incelendi. Bulgular: Malondialdehit yanıtı, müköz ve histopatolojik değerler incelendiğinde, en iyi sonuçlar istatistiksel olarak anlamlı şekilde Ngamma-nitro-L-arginin metil ester ve N-iminoetil-L-ornitin uygulanan gruplarda kaydedildi. Yarışmalı nitrik oksit sentaz inhibitorü Ngamma-nitro-L-arginin metil ester uygulanan grupta süperoksit dismutaz değerlerinde anlamlı iyileşme saptandı. Nitrik oksit değerleri N-iminoetil-L-ornitin grubunda oldukça düşük idi ancak anlamlılık saptanmadı. Sonuç: Künt akciğer travması sonrası pulmoner kontüzyonda serbest oksijen radikalleri ve lipid peroksidasyon rol oynadı. Biyokimyasal ve histopatolojik sonuçlara göre, enflamasyon etkileri hem Ngamma-nitro- L-arginin metil ester hem N-iminoetil-L-ornitin uygulaması ile azaldı ve koruyucu etkiler oluştu.
