Abstract

Purpose: In this study the effect of vitamin E and erdosteine on the activity of hexokinase (HK), glu-cose-6-phosphate dehydrogenase (G6PD), lactate dehydrogenase (LDH) and malate dehydrogenase (MDH) has been assessed in BLM induced lung fibrosis in rats. Materials and Methods: Rats were divided into fourgroups; I-Control (n=8), II- BLM (i.t. one dose 7,5 u/kg) (n=9), III- BLM + vitamin E (intraperitoneal, 10 mg/kğ, 16 day ) (n=9), IV- Blm + erdostein (oral, 10 mg/kg, 16 day) (n=10). Results: The activities of HK, G6PD, LDH and MDH were measured in lung tissue. There was significant increase in enzyme activities in treated rats compared to controls. All of the enzyme activities significantly decreased nearly to the levels of controls in both of the treatment groups (BLM + vitamin E and BLM + erdosteine). The reduction in enzyme activities were similar between treatment groups (BLM + vitamin E and BLM + erdosteine). Conclusion: BLM alters the enzyme activities of main metabolic pathway (especially on lung tissue). It may be suggested that there were preventive effects of vitamin E and erdosteine on the activities of HK, G6PD, LDH and MDH in lung tissue. These results indicate that erdosteine may be a promising drug for protection against bleomycin-induced lung fibrosis.

Özet

Amaç: Bu çalışmada deneysel olarak i.t. BLM uygulanması ile sıçan akciğerinde oluşturulan fibrozisde E vitamini (E vit) ve erdosteinin hekzokinaz (HK), glukoz-6-fosfat dehidrogenaz (G6PD), laktat dehidrogenaz (LDH) ve malat dehidrogenaz (MDH) enzim aktiviteleri üzerine etkilerinin araştırılması planlandı. Gereç ve Yöntem: Sıçanlar I. kontrol (n=8), II. BLM (i.t. tek doz, 7.5 ü/kg) (n=9), III. BLM + E vit (intra peritoneal, 10 mg/kg, 16 gün) (n=9), IV. BLM + erdostein (oral, 10 mg/kg, 16 gün) (n=10) şeklinde 4 gruba ayrıldı. Bulgular: Kontrol grubu ile BLM grubu karşılaştırıldığında, akciğer dokusu HK, G6PD, LDH ve MDH aktivitelerinde BLM grubunda önemli artış olduğu bulundu. BLM grubu ile BLM + E vit ve BLM + erdostein grupları karşılaştırıldığında bütün enzim aktivitelerinde kontrol grubuna yakın önemli bir azalma olduğu gözlendi.Sonuç: BLM diğer dokulara kıyasla çok fazla etkilediği akciğer dokusunda, glukozun girdiği ana metabolik yolların enzimlerini olumsuz yönde etkilediği, E vit ve erdosteinin çalışılan enzim aktiviteleri üzerine daha çok koruyucu yönde etki gösterdiği söylenebilir. Bununda muhtemel sebebinin, BLM'nin akciğer dokusu hasarı oluştururken serbest oksijen radikallerini oluşturması, buna karşılık uyguladığımız antioksidan karakterli E vit ve erdostein maddelerinin serbest radikal süpürücü etkileri ile kısmen hücre ve doku bütünlüğünü koruyarak stabilizasyon sağlaması olduğu söylenebilir.
