Abstract

Background/aims: We aimed to determine the progress of lipid peroxidation and ultrastructural changes established in the rat liver after acute bile duct ligation. Methods: Groups A1, B1, C1 and D1 were the controls of groups A2, B2, C2 and D2, which represented the 1st, 3rd, 5th and 8th days after bile duct ligation. Serum bilirubin and malondialdehyde, liver malondialdehyde and reduced glutathione levels, and inducible nitric oxide synthase expression were determined. Liver tissue was examined with light and electron microscopy. Results: Serum bilirubin increased progressively. Serum and liver malondialdehyde and inducible nitric oxide synthase expression reached a peak level at day 3, reduced at the 5th day and continued at a constant rate. Reduced glutathione decreased progressively. Ductal proliferation increased progressively to a plateau at day 5. The marked electron microscopic changes were detected at day 3 (B2) and continued constantly. Conclusions: The first five days after acute bile duct ligation are the most critical.

Özet

Amaç: Bu çalışmada safra yolu bağlanan sıçanlarda zamana bağlı olarak lipid peroksidasyonu ve karaciğer hücrelerinde oluşan elektron mikroskobik değişikliklerin değerlendirilmesini amaçladık. Yöntem: A1, B1, C1 ve D1 grupları A2, B2, C2 ve D2 gruplarının kontrol grupları olup sırasıyla safra yolu bağlanması sonrası birinci, üçüncü, beşinci ve sekizinci günlere ait örneklerdir. Serum bilirubin ve malondialdehid, karaciğer malondialdehid ve redükte glutathione, indüklenebilir nitrik oksid sentaz ekspresyonu ölçüldü. Karaciğer dokusu elektron mikroskobu ile incelendi. Bulgular: Serum bilirubin sürekli olarak yükseldi. Serum ve karaciğer malondialdehid, ve indüklenebilir nitrik oksid sentaz ekspesyonu üçüncü gün en yüksek seviyeye ulaştı, beşinci gün azaldı ve sabit bir değerde devam etti. Redükte glutathione değeri sürekli azaldı. Ductal proliferasyon sürekli artarak beşinci gün plato oluşturdu. Belirgin elektron mikroskobik değişiklikler üçüncü gün (B2) görüldü ve aynı şekilde devam etti. Sonuç: Akut safra yolu bağlanmasından son-raki ilk beş gün en kritik günlerdir.
