The results of this reseach showed that administration of SF intracolonically had protective effect on the colon injury in the rat model of colitis induced by acetic acid enema, which was probably due to the mechanism of antioxidation, inhibition ofarachidonic acid metabolis and platelets activation, administration of SF intracolonically also showed protective effect on the colon injury in the rat model of colitis induced by trinitrobenzene sulfonic acid and ethanol, which was probably due to antioxidation and inhibition of macrophages activation.

实验研究表明，大鼠分别经乙酸、TNBS和乙醇处理后均出现典型的结肠炎症状，给药后分别评价结肠粘膜损伤指标、结肠组织病理变化，检测结肠组织炎症指标、结肠组织氧化损伤指标及主要炎性细胞因子改变；实验结果：阿魏酸钠对大鼠乙酸性结肠炎结肠粘膜损伤具有缓解保护作用，其机制可能与直接抑制炎症结肠粘膜花生四烯酸代谢过度，抑制血小板活化，清除大量氧自由基有关；阿魏酸钠对大鼠TNBS性结肠炎粘膜免疫损伤亦具有缓解保护作用，其机制可能与抗氧化，抑制结肠巨噬细胞活化有关。
