Özet

BACKGROUND: Pulmonary contusion (PC) is an important life-threatening clinical condition characterized by lung injury and inflammation. Caffeic acid phenethyl ester (CAPE) is a biological agent with potent antioxidant and anti-inflammatory effects. This study aimed to investigate the potential effects of CAPE on tissue damage, nuclear factor kappa-beta (Nf-κβ) activity, inducible nitric oxide synthase (iNOS) synthesis, and pulmonary apoptosis in an experimental PC model. METHODS: Forty adult Wistar albino rats were used in this study and divided into four groups as follows: control, PC, PC + CAPE, and CAPE. CAPE was administered intraperitoneally for seven days following PC formation (10 µmol/kg, dissolved in dimethyl sulfoxide). Wet/dry weight ratio in lung tissue was determined. The pulmonary tissue was examined using hematoxylin–eosin and Masson’s trichrome histochemical staining and also by scanning electron microscopy. Nf-κβ and iNOS activities in the lungs were determined by the indirect immunohistochemical method. Pulmonary apoptosis was detected by the TUNEL method. RESULTS: Increased leukocyte infiltration score, pulmonary edema, alveolar damage, and increased Nf-κβ and iNOS activities were determined in the PC group. CAPE administration inhibited Nf-κβ and iNOS activities and pulmonary apoptosis. CONCLUSION: In this study, the findings showed that CAPE inhibited tissue damage by suppressing inflammatory mediators of Nfκβ and iNOS activities. Also, CAPE was found to be protective in the lung tissue and could be used as a therapeutic agent.

Abstract

AMAÇ: Pulmoner kontüzyon (PC), akciğer hasarı ve enflamasyon ile karakterize, hayatı tehdit eden önemli bir klinik durumdur. Kafeik asit fenetil ester (CAPE), güçlü antioksidan ve anti-enflamatuvar etkileri olan biyolojik bir ajandır. Bu çalışmada, CAPE’nin deneysel PC modelinde doku hasarı, nükleer faktör kappa-beta (Nf-κβ) aktivitesi, indüklenebilir nitrik oksit sentaz (iNOS) sentezi ve pulmoner apoptozis üzerindeki etkileri araştırıldı. GEREÇ VE YÖNTEM: Çalışmada 40 yetişkin Wistar albino sıçanı kullanıldı ve dört gruba ayrıldı: Kontrol, PC, PC + CAPE ve CAPE. CAPE, PC oluşumunu takiben yedi gün boyunca intraperitonal olarak uygulandı (dimetil sülfoksit içinde çözülmüş 10 umol/kg). Akciğer dokusunda ıslak/kuru ağırlık oranı belirlendi. Pulmoner doku hematoksilen-eosin ve masson trikrom histokimyasal boyaması ile ve taramalı elektron mikroskobu ile incelendi. Akciğerlerdeki Nf-κβ ve iNOS aktiviteleri indirekt immünhistokimyasal yöntemle belirlendi. Pulmoner apoptozis, TUNEL yöntemi ile tespit edildi. BULGULAR: Pulmoner kontüzyon grubunda artmış lökosit infiltrasyon skoru, pulmoner ödem, alveoler hasar ve artmış Nf-κβ ve iNOS aktiviteleri tespit edildi. CAPE uygulaması Nf-κβ ve iNOS aktivitelerini ve pulmoner apoptozu azaltmaktadır. TARTIŞMA: Çalışmanın sonuçları, CAPE’nin Nf-κβ ve iNOS enflamatuvar mediatörlerini baskılayarak doku hasarını engellediğini ettiğini açıkça göstermektedir. Ayrıca, CAPE’nin akciğer dokusunda koruyucu olduğunu ve terapötik bir ajan olarak kullanılabileceğini göstermektedir. Anahtar sözcükler: Apoptozis; enflamasyon; indüklenebilir nitrik oksit sentaz; nükleer faktör kappa-beta; pulmoner kontüzyon.
