The objective of this study was to investigate the ameliorative property and potential mechanism of resveratrol (RVT) in a dose of 10 mg/kg for 15 consecutive days against liver injury in streptozotocin-induced diabetic rats. Diabetic rats significantly (P < 0.05) exhibited liver injury manifested by increased aspartylaminotransferase, alanine aminotransferase, and bilirubin; disturbed liver weight to body weight; and confirmed by hematoxylin and eosin staining. Liver from diabetic rats exhibited significant increase in malondialdehyde level and significant decrease in reduced glutathione, glutathione-S-transferase, quinone reductase, catalase, and superoxide dismutase. Diabetic rats showed significant disturbance in serum lipid profile. Treatment with RVT significantly (P < 0.05) abrogated diabetes-induced perturbation in these parameters and liver histology. These data suggest that RVT treatment is associated with promising hepatoprotective effect against diabetes-induced liver damage via reduction of serum glucose level and oxidative damage and improving serum lipid profile.
本研究旨在探讨白藜芦醇(RVT)在 10mg/kg 剂量下连续 15 天对链脲佐菌素诱导的糖尿病大鼠肝损伤的改善作用及其潜在机制。糖尿病大鼠表现出明显的肝损伤,表现为天冬氨酸氨基转移酶、丙氨酸氨基转移酶和胆红素升高;肝重/体重比失调;并通过苏木精和伊红染色证实。糖尿病大鼠的丙二醛水平显著升高,还原型谷胱甘肽、谷胱甘肽-S-转移酶、醌还原酶、过氧化氢酶和超氧化物歧化酶显著降低。糖尿病大鼠的血清脂质谱也出现显著紊乱。RVT 治疗可显著(P<0.05)阻断这些参数和肝组织学的糖尿病诱导的紊乱。这些数据表明,RVT 治疗可能通过降低血糖水平和氧化损伤以及改善血清脂质谱,对糖尿病引起的肝损伤具有潜在的保护作用。
