Recent studies indicate the chemopreventive role of resveratrol in many animal models like ischemia, rheumatoid arthritis, human cancer, and diabetes. The present study was designed to investigate the chemopreventive potential of resveratrol in rat hepatic injury model by carbon tetrachloride. Male Wistar rats were treated with carbon tetrachloride (0.4 g/kg body weight) intraperitoneally daily for 8 weeks. Resveratrol (100 mg/kg, 200 mg/kg body weight) was given orally from first day until the last day of experiment. The investigation assesses the effect of resveratrol on morphological, oxidative status, histopathological, immunohistochemical, and apoptotic analysis in carbon tetrachloride-challenged liver tissue. The study indicated that the inflammatory cytokines TNF-α and IL-6 were profoundly expressed in experimental rats, whereas resveratrol decreases the immunopositivity of TNF-α and IL-6 and restored the altered architectural structure of challenged hepatic tissue. Resveratrol also protects liver cells by suppressing oxidative stress and apoptosis.
最近的研究表明,白藜芦醇在许多动物模型中具有化学预防作用,如缺血、类风湿性关节炎、人类癌症和糖尿病。本研究旨在通过四氯化碳研究白藜芦醇对大鼠肝损伤模型的化学预防潜力。雄性 Wistar 大鼠每天腹膜内注射四氯化碳(0.4 g/kg 体重),共 8 周。白藜芦醇(100mg/kg、200mg/kg 体重)从实验第一天开始至最后一天口服给予。该研究评估了白藜芦醇对四氯化碳刺激的肝组织形态、氧化状态、组织病理学、免疫组织化学和细胞凋亡分析的影响。研究表明,炎性细胞因子 TNF-α 和 IL-6 在实验大鼠中表达明显,而白藜芦醇降低了 TNF-α 和 IL-6 的免疫阳性率,并恢复了受挑战肝组织的改变的结构。白藜芦醇还通过抑制氧化应激和细胞凋亡来保护肝细胞。
