摘要
目的:研究对香豆酸,一种食物中含有的酚酸对佐剂性关节炎大鼠的抗过氧化治疗作用。方法:大鼠右后肢脚垫皮内注射0.1mL弗氏完全佐剂诱发关节炎。于佐剂注射后第11～18天连续给药8d,治疗组用药为对香豆酸(100mg/kg大鼠体质量,腹腔内给药),阳性对照组药物为吲哚美辛(3mg/kg大鼠体质量,腹腔内给药)。对佐剂性关节炎大鼠的肝脏、脾脏、血浆内脂质过氧化作用水平和抗氧化水平的变化进行测量,同时分析大鼠后肢的影像学改变以衡量对香豆酸的抗氧化作用。结果:佐剂性关节炎大鼠经对香豆酸治疗后,脂质过氧化作用和抗氧化水平恢复近正常值。影像学观察发现,治疗组大鼠的软组织肿胀、骨侵蚀及关节间隙狭窄情况得到缓解。结论:对香豆酸对佐剂性关节炎大鼠有明显的治疗作用,这种治疗作用可能与其抗氧化作用相关。
OBJECTIVE： The present study was designed to investigate the antiperoxidative potential of p-coumaric acid, a common dietary phenol, in adjuvant-induced arthritis in rats. METHODS： Arthritis was induced by an intradermal injection of 0.1 mL complete Freund＇s adjuvant in the foot pad of right hind limb of rats. p-Coumaric acid （]00 mg/kg body weight, intraperitoneally） and the reference drug indomethacin （3 mg/kg body weight, intraperitoneally） were administered to arthritic rats for 8 d from the 11th day to the 18th day after adjuvant injection. The antiperoxidative effect of p-coumaric acid was investigated by assessing changes in lipid peroxidation levels and antioxidant status in liver, spleen and plasma of the adjuvant-induced arthritic rats. In addition, radiological changes in hind limbs of the arthritic rats were also analyzed. RESULTS： p-Coumaric acid treatment reversed the altered lipid peroxidation and antioxidant status observed in arthritic rats to near normal levels. Soft swelling, bone erosion, and joint space narrowing noticed in arthritic rats were found to be mitigated in p-coumaric acid-treated arthritic rats.CONCLUSION： The study clearly exhibits the antiperoxidative potential of p-coumaric acid against adjuvant-induced arthritis in rats.
