Purpose: In this study, we
evaluated the potential hepatoprotective effects of silymarin on valproic
acid-induced liver injury by histological and biochemical parameters in rat
liver.

Method:Experimental procedures
were performed on 21 male Sprague Dawley rats. Rats were divided into three
groups: group 1, control; group 2, valproic acid; group 3, valproic acid +
silymarin. The groups were administered 500 mg/kg/day valproic acidand 100
mg/kg/daysilymarin for 14 days, except control group.

Results:Silymarin treatment decreased
the levels of serumgamma glutamyl transferase, alanine amino transferase, aspartate
aminotransferase and increreased serum albumin levelssignificantly (p
<0.05). In addition, increased amount of malondialdehyde and decreased
levels of glutathione with valproic acid were significantly suppressed by
silymarin in liver tissue (p <0.05). The combination of silymarinwith valproic
acid reduced loss of body weight in the present study. Histologically, the
extent of liver damage was significantly lower in the valproic acid+silymarin
group (p<0.005). Oxidative stress was decreased, antioxidant activity was
increased and histopathological changes were reduced in the valproic acid + silymarin
group compared to the valproic acid group.

Conclusion:This study revealed that
the liver injury induced by valproic acid was attenuated with silymarin
administration. Silymarincan protect rat liver against valproic acid induced
injury by its anti-oxidative effect,
and might be useful for reducing the severity of liver injury.

Silimarinin, ratlarda valproik asitin indüklediği karaciğer hasarı üzerine olumlu etkilerinin araştırılması

Öz

Amaç:Bu çalışmada; valproik asit kaynaklı ratlarda
karaciğer hasarına karşı silimarin'in olası hepatoprotektif etkilerini
histolojik ve biyokimyasal değerlendirmeler kullanarak araştırmayı amaçladık.

Gereç ve yöntemler:Deneysel işlemler, 21 adet Sprague
Dawley sıçanı üzerinde gerçekleştirildi. Sıçanlar üç gruba ayrıldı: grup 1,
kontrol; grup 2, valproik asit; grup 3, valproik asit + silimarin. Gruplara,
kontrol grubu hariç 500 mg/kg/gün valproik asit ve 100 mg/kg/gün silimarin 14
gün  uygulandı.

Bulgular:Valproik asitile artan serum gama glutamil transferaz,
alanin amino transferaz, aspartat aminotransferaz ve azalan serum albumin
seviyesi silimarin tedavisi ile tersine çevrildi (p<0.05). Ek olarak,
karaciğer dokusunda valproik asit ile malondialdehit seviyesinin artması ve glutatyon
seviyesinin azalması, silimarin tarafından önemli ölçüde baskılandı (p<0.05).
Silimarin'in,valproik asit ile kombinasyonu bu çalışmada vücut ağırlığı kaybını
azaltmıştır. Histolojik olarak, valproik asit + silimarin grubunda karaciğer
hasarının derecesi anlamlı olarak dah düşük bulundu (p <0.005). Valproik
asit + silimarin grubunda; valproik asit grubuna göre oksidatif streste azalma,
antioksidan aktivitede artışve histopatolojik değişikliklerde azalma kaydedildi.

Sonuç:Bu çalışma valproik asit'in indüklediği karaciğer
hasarının silimarin uygulaması ile azaldığını ortaya konuldu. Silimarin, sıçan
karaciğerini anti-oksidatif etkisi ile valproik asit kaynaklı hasara karşı
koruyabilir ve karaciğer hasarının boyutunu azaltmak için faydalı olabilir.
