Abstract

Background: In this study, injury in the lungs due to ischemia/reperfusion (I/R) and preventive effect of pentoxifylline, carnitine and ascorbic acid were investigated. Methods: Twenty-nine rats were randomized into five groups: 1) Control (Group 1); 2) I/R group (Group 2); 3) Animals were pretreated with pentoxyfilline (Group 3); 4) Animals were pretreated with carnitine (Group 4); 5) Animals were pretreated with ascorbic acid (Group 5). Rats in the Group 1 were undertaken laparotomy and closed after exploration of abdominal aorta. In the second group, the infrarenal aorta of the rats were clamped for a period of 3 hours. After ischemic period, aortic clamping were removed and waited for 1 hour of reperfusion period. The rats in the 3., 4., and 5. Group were administered pentoxifylline, carnitine and ascorbic acid, respectively. The animals were sacrificed and the histological specimens of the lungs were examined. Lung injury was rated with a semi-quantitative score based on congestion, interstitial edema, and polymorph nuclear leukocyte (PMNL) infiltration. Results: Edema, congestion and the more prominent accumulation of PMNL were determined in the specimens of other four groups as compared to the control group. The average scores were 0.6 in Group 1; 2.6 in Group 2; 2.16 in Group 3; 2.28 in Group 4; 1.83 in Group 5, respectively. Conclusions: Pretreatment with pentoxifylline, carnitine and ascorbic acid were found to be beneficial in prevention of lung injury after IR of infrarenal aortic occlusion.

Özet

Amaç: Bu çalışmada, geçici iskemi reperfüzyona (İ/R) bağlı olarak ortaya çıkan akciğer hasarını önlemede pentoksifilin, karnitin ve askorbik asidin etkileri incelendi. Materyal ve Metod: Çalışmaya alınan 29 adet rat, kontrol grubu (Grup 1), İ/R grubu (Grup 2), askorbik asit verilen grup (Grup 3), karnitin verilen grup (Grup 4), ve pentoksifilin verilen grup (Grup 5) olmak üzere beş gruba ayrıldı. Grup 1'deki ratlara sadece anestezi verildi ve batın açılıp abdominal aorta eksplore edildikten sonra hiçbir girişim yapılmadan tekrar kapatıldı. İkinci grupta batın açıldıktan sonra abdomimal aorta eksplore edildi ve infrarenal aortaya klemp konularak batın kapatıldı. Üç saatlik iskemi, 1 saatlik reperfüzyon süresi beklendi. Aynı işlem 3. 4. ve 5. gruplara da uygulandı, ayrıca bu gruplara sırasıyla askorbik asit, karnitin ve pentoksifilin verildi. Yapılan işlem tamamlandıktan sonra ratların akciğerleri çıkartıldı ve histolojik inceleme yapıldı. Büyütme alanı içerisinde bulunan akciğer dokusundaki polimorf nüveli lökositler (PMNL), konjesyon ve interstisiyel ödem semikantitatif olarak değerlendirilerek akciğer hasarı tespit edildi. Bulgular: Kontrol grubuna göre diğer dört grupta daha fazla PMNL birikimi, ödem ve konjesyon vardı. İkinci grup ile kıyaslandığında ise ilaç tedavisi verilen 3. 4. ve 5. gruplarda PMNL sayısının daha az olduğu görüldü. Semikantitatif değerlendirmede hesaplanan hasar skor puanı kontrol grubunda 0.6, 2. grupta 2.6, 3. grupta 2.16, 4. grupta 2.28 ve 5. grupta 1.83 olarak bulundu. Sonuç: İnfrarenal aort oklüzyonuna bağlı olarak ortaya çıkan geçici iskemi ve reperfüzyonun akciğer dokusu üzerinde yaptığı hasarı önlemede askorbik asidin, karnitinin ve pentoksifilinin yararlı etkileri olduğu sonucuna ulaşıldı.
