The present study aimed to investigate the preventive effects of methanol fraction from leaf extract (MECA), associated with its phytochemical content, on CCl-induced hepatic toxicity in adult rats. In the controls, CCl induced an increase of serum biochemical parameters and triggered oxidative stress in the liver. MECA caused significant reductions in CCl-elevated levels of hepatic markers, total cholesterol, triglycerides, and low-density lipoprotein and increased the level of high-density lipoprotein compared to the CCl group. Moreover, pretreatment with the MECA produced significant reductions in lipid peroxidation (thiobarbituric acid reactive substances) and protein carbonyl level in liver tissues as compared with the untreated group. The formation of pathological hepatic lesions was strongly prevented by MECA. Overall, this study suggests that administration of MECA has a high potential to quench free radicals and alleviate CCl-induced hepatotoxicity in rats.
本研究旨在探讨叶提取物甲醇组分(MECA)及其植物化学成分对成年大鼠四氯化碳诱导的肝毒性的预防作用。在对照组中,四氯化碳导致血清生化参数升高并引发肝脏氧化应激。与四氯化碳组相比,MECA使四氯化碳升高的肝脏标志物、总胆固醇、甘油三酯和低密度脂蛋白水平显著降低,并提高了高密度脂蛋白水平。此外,与未处理组相比,用MECA预处理可使肝组织中的脂质过氧化(硫代巴比妥酸反应性物质)和蛋白质羰基水平显著降低。MECA强烈预防了病理性肝损伤的形成。总体而言,本研究表明,给予MECA具有清除自由基和减轻大鼠四氯化碳诱导的肝毒性的巨大潜力。
