Mitochondrial oxidative damage is a crucial factor in the pathogenesis of diabetic nephropathy (DN), which is among the most prevalent problems of diabetes, and there hasn't been an effective treatment for DN yet. This study planned to investigate the effects of L. on mitochondrial function along with its protection against streptozotocin-induced nephropathy in diabetic mice. After the injection of streptozotocin (STZ) and verification of the establishment of diabetes, mice ( = 30) were randomly divided into the following groups: control group, diabetic-control, -treated diabetic (50, 100, and 200 mg/kg), and metformin-treated diabetic group (500 mg/kg). After four weeks of treatment, the mice were weighed. Blood and kidney tissues were examined for biochemical and histological evaluation. Hematoxylin and eosin staining was used for evaluating renal pathologic damage. Oxidative damage in the kidney was assessed by the evaluation of lipid peroxidation and glutathione oxidation. Furthermore, differential centrifugation was used to obtain the isolated mitochondria, and mitochondrial toxicity endpoints (mitochondrial function and mitochondrial oxidative markers) were determined in them. remarkably reduced the blood urea and creatinine concentrations, and also normalized kidney weight/body weight coefficient in the diabetic mice. . ameliorated the incidence of glomerular and tubular pathological changes in histological analyses. Moreover, the oxidative and mitochondrial damages were notably attenuated in renal tissues of -treated mice. These results indicate that the methanolic extract of modulates the nephropathy in the diabetic mice by the amelioration of oxidatively induced mitochondrial damage and provides a reliable scientific base, suggesting as a promising alternative remedy against DN.
线粒体氧化损伤是糖尿病肾病(DN)发病机制中的关键因素,糖尿病肾病是糖尿病最常见的问题之一,目前尚无针对DN的有效治疗方法。本研究旨在探讨L.对糖尿病小鼠线粒体功能的影响及其对链脲佐菌素诱导的肾病的保护作用。注射链脲佐菌素(STZ)并验证糖尿病模型建立后,将30只小鼠随机分为以下几组:对照组、糖尿病对照组、L.治疗糖尿病组(50、100和200mg/kg)以及二甲双胍治疗糖尿病组(500mg/kg)。治疗四周后,对小鼠进行称重。对血液和肾脏组织进行生化和组织学评估。苏木精和伊红染色用于评估肾脏病理损伤。通过评估脂质过氧化和谷胱甘肽氧化来评估肾脏中的氧化损伤。此外,采用差速离心法获得分离的线粒体,并测定其中的线粒体毒性终点(线粒体功能和线粒体氧化标志物)。L.显著降低了糖尿病小鼠的血尿素和肌酐浓度,并使肾脏重量/体重系数恢复正常。L.改善了组织学分析中肾小球和肾小管病理变化的发生率。此外,L.治疗的小鼠肾组织中的氧化损伤和线粒体损伤明显减轻。这些结果表明,L.的甲醇提取物通过改善氧化诱导的线粒体损伤来调节糖尿病小鼠的肾病,为其作为一种有前景的DN替代治疗药物提供了可靠的科学依据。
