Present investigation aimed to evaluate the hepatoprotective potential of resveratrol (30mg/kg, po) in mice following two different routes (po and sc) of exposure to carbon tetrachloride (CCl(4), 1.0ml/kg). Administration of CCl(4) caused significant increase in the release of transaminases, alkaline phosphatase, lactate dehydrogenase, γ-glutamyl transpeptidase, creatinine kinase, total bilirubin, urea and uric acid in serum. Significantly enhanced hepatic lipid peroxidation and oxidized glutathione with marked depletion in reduced glutathione were observed after CCl(4) intoxication. It was also found that CCl(4) administration caused severe alterations in liver histology. Hepatic injury was more severe in those animals who received CCl(4) by oral route than those who exposed to CCl(4) subcutaneously. Resveratrol treatment was able to mitigate hepatic damage induced by acute intoxication of CCl(4) and showed pronounced curative effect against lipid peroxidation and deviated serum enzymatic variables as well as maintained glutathione status toward control. Treatment of resveratrol lessened CCl(4) induced damage in liver. The results of the present study suggest that resveratrol has potential to exert curative effects against liver injury.
本研究旨在评估白藜芦醇(30mg/kg,po)在两种不同途径(po 和 sc)暴露于四氯化碳(CCl(4),1.0ml/kg)后对小鼠的肝脏保护作用。CCl(4)的给予导致血清中转氨酶、碱性磷酸酶、乳酸脱氢酶、γ-谷氨酰转肽酶、肌酸激酶、总胆红素、尿素和尿酸的释放显著增加。CCl(4)中毒后,观察到肝脂质过氧化和氧化型谷胱甘肽明显增加,而还原型谷胱甘肽明显减少。还发现 CCl(4)的给予导致肝组织学的严重改变。经口给予 CCl(4)的动物的肝损伤比经皮下给予 CCl(4)的动物更严重。白藜芦醇治疗能够减轻 CCl(4)急性中毒引起的肝损伤,并对脂质过氧化和偏离的血清酶学变量显示出明显的治疗效果,同时维持谷胱甘肽状态接近对照。白藜芦醇的治疗减轻了 CCl(4)引起的肝损伤。本研究结果表明,白藜芦醇具有对肝损伤发挥治疗作用的潜力。
