ABSTRACT
Background: Hepatotoxicity induced by Cyclosporine A (CsA) remains one of the major side effects. The aim of this studywas to determine the protective effects of beet root (Beta Vulgaris L) extract and silymarin against hepatotoxicity induced byCyclosporine A in rats. Methods: Sixty male albino rats, were divided into 6 groups (n=10). Group I control group. GroupII CsA-treated and received (50mg/kg weight, orally). Group III received (500mg/kg b.wt) beet root extract orally. Group IVreceived beet root extract and CsA as in group II and III. Group V was received (100 mg/kg b.wt) silymarin orally. Group VIreceived CsA and silymarin as in group II and V. Serum levels of (ALT, AST, ALP) and bilirubin (Total and Direct) weremeasured. Oxidative stress biomarkers, antioxidant status, damage to DNA, apoptosis and inflammatory mediators weremeasured in the tissues of the liver. Result: CsA administration significantly increased serum levels of the liver enzymesALT, AST, ALP and bilirubin. In addition, significant increase in MDA, Nitrite, 8-OHdG, caspase3, NF-κB, TNF-α andsignificant decrease of GST in liver tissues was noticed. Furthermore, histopathological changes occurred in CsA treatedrats exhibited disruption of normal liver architecture, congested central vein, vacuolated cytoplasm and inflammatory cellsinfiltration. Co-administration of beet root extract or silymarin +CsA ameliorated all these parameters. Conclusion: Thepresent study suggests that beet root extract and silymarin have beneficial effect in reducing hepatotoxicity induced by CsAvia decreasing oxidative stress, inflammation, DNA damage, apoptosis and repairing the histopathological changes.
