Abstract

Intestinal ischemia-reperfusion injury (II/R) is a condition with significant morbidity and mortality. In this study, we aimed to demonstrate the protective effect of carnosol, an anti-oxidant, anti-inflammatory, anti-carcinogenic and anti-microbial agent, on pro-inflammatory cytokines, tissue angiopoietins, histopathological damage and bacterial translocation in rats subjected to II/R injury. Thirty male Sprague-Dawley rats were divided into 3 groups: control group, intestinal ischemia/reperfusion group (II/R) and carnosol group (II/R+C). Ischemia-reperfusion injury was conducted by laparotomy. All rats received 1010 colony forming units/milliliters E.coli 12 hours prior to surgery. II/R+C rats received 3 mg/kg/day carnosol per oral starting from 3 days prior to surgery. After 72 hours of post-surgical follow-up, rats were re-laparotomized for specimen collection. II/R+C group had lower serum TNF-α, IL-1β and IL-6 levels when compared with II/R group (p=0.026, 0.006 and 0.045, respectively). II/R group had significantly higher tissue injury when compared with II/R+C group (p<0.001). II/R+C group rats had significantly reduced liver, spleen and mesenteric lymph node culture growths when compared with II/R group. Angiopoietin I and II levels were similar between groups. In conclusion, carnosol is a powerful anti-inflammatory and anti-microbial agent in II/R injury model. We showed effective reduction of pro-inflammatory cytokine profile, improvement of histopathological damage, and prevention of bacterial translocation.

KARNOSOL SIÇANLARDA BAĞIRSAK İSKEMİ-REPERFÜZYON MODELİNDE İNFLAMASYON VE BAKTERİYEL TRANSLOKASYONU HAFİFLETİR

Abstract

İntestinal iskemi-reperfüzyon hasarı (II/R), önemli morbidite ve mortaliteye sahip bir durumdur. Bu çalışmada, anti-oksidan, anti-enflamatuvar, anti-karsinojenik ve anti-mikrobiyal bir ajan olan karnosolün II/R modeli uygulanan sıçanlarda pro-inflamatuar sitokinler, doku anjiopoietinleri, histopatolojik hasar ve bakteriyel translokasyon üzerindeki koruyucu etkisini göstermek amaçlanmıştır. Otuz erkek Sprague-Dawley sıçanı 3 gruba ayrıldı: kontrol grubu, intestinal iskemi/reperfüzyon grubu (II/R) ve karnosol grubu (II/ R+C). İskemi-reperfüzyon hasarı laparotomi ile sağlandı. Tüm sıçanlara ameliyattan 12 saat önce 1010 koloni oluşturan birim/mililitre E.coli uygulandı. II/R+C grubuna, ameliyattan 3 gün önce başlayarak oral 3 mg/kg/gün karnosol uygulandı. Ameliyat sonrası takipten 72 saat sonra, sıçanlar örnek toplama için yeniden laparotomize edildi. II/R+C grubunun II/R grubuna göre serum TNF-α, IL-1β ve IL-6 düzeyleri anlamlı derecede azalmıştı (sırasıyla p=0.026, 0.006 ve 0.045). II/R grubunun, II/R+C grubuna göre daha şiddetli doku hasarına maruz kaldığı görüldü (p<0.001). II/R+C grubu, II/R grubu ile karşılaştırıldığında, karaciğer, dalak ve mezenterik lenf nodu kültür pozitifliğinin anlamlı düzeyde azalmış olduğu gösterilmiştir. Anjiyopoietin I ve II düzeyleri gruplar arasında benzerdi. Sonuç olarak, karnosol güçlü bir anti-inflamatuar ve anti-mikrobiyal ajandır. Bu çalışmada karnosolun II/R modelinde pro-inflamatuar sitokin profilinin etkili bir şekilde azaltan, histopatolojik hasarı düzelten ve bakteriyel translokasyonu önleyen bir ajan olduğu gösterilmiştir.
