Acute pancreatitis is a morbid inflammatory condition of pancreas with limited specific therapy. Enhanced oxidative stress plays an important role in induction and progression of acute pancreatitis. So reducing oxidative stress may relieve this pathogenic process. Echium amoenum Fisch. and Mey has been implemented in Iranian folk medicine for several centuries. Antioxidant, analgesic, immunomodulatory, and anxiolytic properties of E. amoenum suggest that this plant may have beneficial effects in the management of acute pancreatitis. The aim of this study was to evaluate the protective effect of petals of E. amoenum extract (EAE) on a murine model of pancreatitis. Acute pancreatitis was induced by five intraperitoneal (i.p.) injection of cerulein (50 μg/kg) with 1h intervals which was characterized by pancreatic inflammation and increase in the serum level of digestive enzymes, in comparison to normal mice. EAE (100, 200, and 400 mg/kg) was administered i.p., 30 minutes before induction of pancreatitis. Pretreatment with EAE (400 mg/kg) reduced significantly the inflammatory response of cerulein-induced acute pancreatitis by ameliorating pancreatic edema, amylase and lipase serum levels, proinflammatory cytokines, myeloperoxidase activity, lipid peroxidation and pathological alteration. These results show that EAE attenuates the severity of cerulein-induced acute pancreatitis with an anti-inflammatory, immunomodulatory and antioxidant effects.
急性胰腺炎是胰腺的一种病态炎症,特异性治疗方法有限。增强的氧化应激在急性胰腺炎的诱导和进展中起重要作用。因此,减轻氧化应激可能会缓解这一致病过程。几个世纪以来,琉璃苣在伊朗民间医学中一直被使用。琉璃苣的抗氧化、镇痛、免疫调节和抗焦虑特性表明,这种植物可能对急性胰腺炎的治疗有有益作用。本研究的目的是评估琉璃苣提取物(EAE)花瓣对小鼠胰腺炎模型的保护作用。与正常小鼠相比,通过腹腔注射(i.p.)5次雨蛙肽(50μg/kg),间隔1小时诱导急性胰腺炎,其特征为胰腺炎症和血清消化酶水平升高。在诱导胰腺炎前30分钟腹腔注射EAE(100、200和400mg/kg)。用EAE(400mg/kg)预处理可通过改善胰腺水肿、淀粉酶和脂肪酶血清水平、促炎细胞因子、髓过氧化物酶活性、脂质过氧化和病理改变,显著降低雨蛙肽诱导的急性胰腺炎的炎症反应。这些结果表明,EAE通过抗炎、免疫调节和抗氧化作用减轻了雨蛙肽诱导的急性胰腺炎的严重程度。
