Abstract

Resveratrol (RES) is a traditional Chinese herbal medicine having anti-inflammatory properties. We sought to explore the role of RES in intestinal injury during severe acute pancreatitis (SAP) in a rat model study. For this purpose, RES-treated and sham-operated (SO) SAP rat models were established, and SAP was induced in rats by injecting 4% sodium taurocholate into the biliary-pancreatic duct. In the RES group, RES was infused intravenously immediately after the SAP induction in rats; SO group served as controls. Histopathological analysis, determination of tissue levels of superoxide dismutase (SOD) and malondialdehyde (MDA) and serum levels of TNF-α as well as ICAM-1 and VCAM-1 expression were carried out at 3, 6, and 12 h following SAP induction. The data show that following SAP induction, SOD levels decreased and MDA levels increased along with ICAM-1 and VCAM-1 expression in the intestine. Serum TNF-α levels increased in the SAP group. Importantly, RES treatment significantly reversed all the pathological changes. In conclusion, this study confirmed the anti-inflammatory properties of RES and demonstrated the prevention of injury to the intestinal barrier in the rat SAP model.

摘要

白藜芦醇(RES)是一种具有抗炎特性的传统中药。我们试图在大鼠模型研究中探索 RES 在重症急性胰腺炎(SAP)期间肠损伤中的作用。为此,建立了 RES 治疗和假手术(SO)SAP 大鼠模型,并通过向胆管胰管注射 4%牛磺胆酸钠诱导大鼠 SAP。在 RES 组中,在诱导 SAP 后立即静脉内输注 RES;SO 组作为对照。在 SAP 诱导后 3、6 和 12 小时进行组织中超氧化物歧化酶(SOD)和丙二醛(MDA)水平以及血清肿瘤坏死因子-α(TNF-α)和细胞间黏附分子-1(ICAM-1)和血管细胞黏附分子-1(VCAM-1)表达的组织学分析。结果表明,SAP 诱导后,肠道中 SOD 水平降低,MDA 水平升高,同时 ICAM-1 和 VCAM-1 表达增加。SAP 组血清 TNF-α 水平升高。重要的是,RES 治疗显著逆转了所有的病理变化。综上所述,本研究证实了 RES 的抗炎特性,并证明了它可以预防大鼠 SAP 模型中肠屏障损伤。
