This study, it was investigated whether silymarin has a protective effect by performing histological, immunohistochemical, and biochemical evaluations on the liver damage induced by cecal ligation perforation (CLP). CLP model was established and silymarin was treated at a dose of 50 mg/kg, 100 mg/kg, and 200 mg/kg, by oral one hour before the CLP. As an effect of the histological evaluations of the liver tissues, venous congestion, inflammation, and necrosis in the hepatocytes were observed in the CLP group. A situation close to the control group was observed in the Silymarin (SM)100 and SM200 groups. As a result of the immunohistochemical evaluations, inducible nitric oxide synthase (iNOS), cytokeratine (CK)18, Tumor necrosis factor-alpha (TNF-α), and interleukine (IL)-6 immunoreactivities were intense in the CLP group. In the biochemical analysis, Alkaline Phosphatase (ALP), Aspartate Aminotransferase (AST), and Alanine Aminotransferase (ALT) levels were significantly increased in the CLP group, while a significant decrease was observed in the treatment groups. TNFα, IL-1β, and IL-6 concentrations were in parallel with histopathological evaluations. In the biochemical analysis, Malondialdehyte (MDA) level increased significantly in the CLP group, but there was a significant decrease in the SM100 and SM200 groups. Glutathione (GSH), Superoxide Dismutase (SOD), Catalase (CAT), and Glutathione Peroxidase (GSH-Px) activities were relatively low in the CLP group. According to these data, it was concluded that using silymarin reduces the existing liver damage in sepsis.
本研究通过对盲肠结扎穿孔(CLP)诱导的肝损伤进行组织学、免疫组织化学和生化评估,来探究水飞蓟素是否具有保护作用。建立CLP模型,并在CLP前1小时口服给予水飞蓟素,剂量分别为50mg/kg、100mg/kg和200mg/kg。肝组织的组织学评估结果显示,CLP组出现静脉淤血、炎症以及肝细胞坏死。水飞蓟素(SM)100和SM200组观察到接近对照组的情况。免疫组织化学评估结果显示,CLP组诱导型一氧化氮合酶(iNOS)、细胞角蛋白(CK)18、肿瘤坏死因子-α(TNF-α)和白细胞介素(IL)-6免疫反应强烈。生化分析中,CLP组碱性磷酸酶(ALP)、天冬氨酸转氨酶(AST)和丙氨酸转氨酶(ALT)水平显著升高,而治疗组则显著降低。TNFα、IL-1β和IL-6浓度与组织病理学评估结果一致。生化分析中,CLP组丙二醛(MDA)水平显著升高,但SM100和SM200组则显著降低。CLP组谷胱甘肽(GSH)、超氧化物歧化酶(SOD)、过氧化氢酶(CAT)和谷胱甘肽过氧化物酶(GSH-Px)活性相对较低。根据这些数据得出结论,使用水飞蓟素可减轻脓毒症中现有的肝损伤。
