Abstract

Abstract In the present study we investigated the hepatoprotective effect of the water extract of Viburnum lantana L. (VL) leaves on carbon tetrachloride (CCl4)-induced hepatotoxicity in rats, hypoglycemic activity and lethal doses of the same extract in mice. Biochemical parameters of hepatic damage such as serum aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP) and bilirubin concentrations were determined. CCl4 (0.8 mL/kg i.p. for 7 days) treatment increased the serum AST, ALT, ALP and bilirubin levels significantly as compared to controls. Treatment of animals with silibinin (50 mg/kg) + CCl4 (0.8 mL/kg i.p.) or VL (100 mg/kg, i.p.) + CCl4 (0.8 mL/kg i.p.) for 7 days significantly ameliorated the levels of AST, ALT and ALP elevated by the CCl4 treatment alone. The results of biochemical tests were also confirmed by histopathological examination. The livers of the group treated with VL showed less balooning degeneration and apoptosis. Necrosis had not been observed in VL group. These results suggest that, liver damage occured in VL-treated group is less than the damage occured in silibinin-treated group. To evaluate of hypoglicemic activity of VL, glibenclamide was used as the reference agent. But, VL has not hypoglycemic activity in healthy and diabetic mice.

Özet

Bu çalışmada Viburnum lantana L. (VL) yapraklarının sulu ekstresinin, sıçanlarda karbon tetraklorür (CCl4) nedenli hepatotoksisite üzerine hepatoprotektif etkisi, farelerde letal dozu ve hipoglisemik aktivitesi araştırılmıştır. Serum aspartat amino transferaz (AST), alanin amino transferaz (ALT), alkalin fosfataz (ALP) ve bilirubin konsantrasyonu gibi karaciğer hasarının biyokimyasal parametrelerine bakılmıştır. CCl4 (0.8 mL/kg i.p., 7 gün) grubunda serum AST, ALT, ALP ve bilirubin seviyelerinin kontrol grubuyla kıyaslandığında anlamlı seviyede arttığı görülmüştür. Sıçanlara silibinin (50 mg/kg)+CCl4 (0.8 mL/kg i.p.) ve VL (100 mg/kg, i.p.) + CCl4 (0.8 mL/kg i.p.) 7 gün boyunca uygulandığında, tek başına CCl4 uygulandığındaki yükselen serum AST, ALT ve ALP seviyeleri anlamlı bir şekilde düşmüştür. Biyokimyasal testlerin sonuçları histopatolojik incelemelerle de doğrulanmıştır. VL uygulanan grubun karaciğerlerinde daha az balon dejenerasyonu ve apoptozis görülmüştür. Bu grupta da nekroz gözlenmemiştir. Bu sonuçlar VL uygulanan gruptaki karaciðer hasarının silibinin uygulanan grupta gözlenen hasardan daha az olduğunu göstermektedir. VL.nin hipoglisemik aktivitesini değerlendirmek için glibenklamid referans madde olarak kullanılmıştır. Fakat VL, sağlıklı ve diyabetik farelerde hipoglisemik aktivite göstermemiştir.
