Abstract

Background/aims: Partial hepatectomy is performed for the treatment of mass lesions in the liver. Lycopene, which is a carotenoid, is present in various physiologic processes. In this study, the effects of lycopene administration in partially hepatectomized rats were evaluated by assessing various oxidant/antioxidant parameters, remnant liver histology and plasma nitric oxide levels. Methods: Thirty Wistar albino adult male rats were randomly divided into three equal groups as: Sham, Partial Hepatectomy and Lycopene-Administered + Partial Hepatectomy groups. Lycopene (4 mg/kg), which was dissolved in olive oil, was given to the rats per orally (via gavage tube) (0.1 ml) every day for 6 weeks before partial hepatectomy and for one week after partial hepatectomy. Tissue and blood samples were collected one week after partial hepatectomy. Results: Plasma malondialdehyde (p<0.001) and nitric oxide (p<0.05) levels in the lycopene-administered + partial hepatectomy group were significantly higher than in the partial hepatectomy group. Intraerythrocytic glutathione (p<0.001), plasma (p<0.001) and liver tissue Cu-Zn (p<0.05) superoxide dismutase levels of the lycopene-administered + partial hepatectomy group were significantly lower than in the partial hepatectomy group. Conclusions: Lycopene administration could be harmful by increasing oxidative stress after partial hepatectomy.

Özet

Amaç: Parsiyel hepatektomi karaciğerin kitlesel lezyonlarının tedavisinde uygulanmaktadır. Likopen bir karotenoittir ve birçok fizyolojik mekanizmanın içinde yer alır. Bu çalışmada, sıçanlarda parsiyel hepatektomi sonrası likopen uygulamasının oksidan ve antioksidan parametreler, kalan karaciğer histolojisi ve plazma nitrik oksit düzeyi üzerine etkileri değerlendirildi. Yöntem: Otuz adet Wistar albino yetişkin erkek sıçan rastlantısal olarak üç eşit gruba ayıldı: Sham grubu, parsiyel hepatektomi grubu, likopen verilen parsiyel hepatektomi grubu. Likopen (4 mg/kg) zeytin yağında çözüldü ve hepatektomi öncesi altı hafta ve hepatektomi sonrası bir hafta gavaj ile transoral olarak (0,1 ml) verildi. Doku ve kan örnekleri hepatektomiden bir hafta sonra alındı. Bulgular: Likopen verilen parsiyel hepatektomi grubunun plazma malondialdehit (p<0.001) ve nitrik oksit (p<0.05) seviyeleri parsiyel hepatektomi grubundan anlamlı derecede yüksekti. Likopen verilen parsiyel hepatektomi grubunun eritrosit içi glutatyon (p<0.001), plazma (p<0.001) ve karaciğer dokusu Cu-Zn (p<0.05) süper oksit dismutaz seviyeleri parsiyel hepatektomi grubundan anlamlı derecede düşüktü. Sonuç: Parsiyel hepatektomi sonrası likopen uygulaması oksidatif stresi arttırarak zararlı olabilir.
