摘要
本研究旨在探讨雌二醇（ESG）对 CFA 诱导的大鼠关节炎的药理作用。给大鼠注射 CFA 诱导关节炎，然后将大鼠随机分为五组，其中三组对应不同剂量的 ESG，另外两组分别为对照组和 CFA-关节炎对照组。研究结果表明，ESG 以剂量依赖的方式改善了大鼠的体重和关节炎评分，后爪体积的减少也证明了这一点。ESG 还能降低 MDA 水平，提高内源性抗氧化剂 SOD 和 GPx 的浓度，从而改善大鼠的抗氧化状态。与 CFA 组相比，ESG 治疗组的促炎细胞因子水平也有所降低。在 Western 印迹分析中，ESH 显示 p-JAK-2/STAT-3 下调。这项研究为 ESG 对大鼠类风湿性关节炎的保护作用提供了具体证据。
Estragole Ameliorates CFA Induced Rheumatoid Arthritis Symptoms in Wistar Rats by Inhibiting JAK-2/STAT-3 Pathway.
The present study was conducted to scrutinize the pharmacological effect of Estragole (ESG) against CFA-induced arthritis in rats. The rats underwent induction of arthritis using the administration of CFA and after that, the rats were randomly divided into five different groups, where three groups correspond to diverse dosages of ESG, and the other two were control and CFA-arthritic control. Results of the study suggested that ESG in a dose-dependent manner, improves body weight and arthritis score of rats as evidenced by reduction of hind-paw volume. ESG also improved the antioxidant status of rats by reducing MDA levels and enhancing the concentration of endogenous antioxidants SOD and GPx. The level of pro-inflammatory cytokines was also found to be reduced in the case of ESG treated group as compared to CFA-group. In a western blot analysis, ESH showed downregulation of p-JAK-2/STAT-3. The study provided concrete evidence for the protective effect of ESG against rheumatoid arthritis in rats.
