【摘要】 目的：阐明豨莶草抗风湿作用机理。方法：建立佐剂性关节炎（ａｄｊｕｖａｎｔ ａｒｔｈｒｉｔｉｓ，ＡＡ）大鼠模型。观察豨莶草活性部位对ＡＡ大鼠淋巴细胞增殖反应、白细胞介素一１（ＩＬ－１）、白细胞介素一２（ＩＬ一2）活性的影响，并同时观察ＡＡ大鼠踝关节病理切片，以及豨莶草的镇痛作用。结果：豨莶草可减轻ＡＡ大鼠踝关节炎症等病理反应；有较好的镇痛作用，镇痛率为６５％。豨莶草可增强ＡＡ大鼠Ｔ细胞的增殖功能，促进ＩＬ－２的活性，抑制ＩＬ－１的活性，与对照组比较有显著性差异（Ｐ ＜ ０．０１）。结论：豨荃草可通过调整机体免疫功能，改善局部病理反应而达到抗风湿作用。更多还原

【Abstract】 To explore the mechanism of anti-rheumatism action of the active fraction of Herba Siegesbeckiae (AFHS). Methods: Adujvant arthritis model of rat was made to observe the effect of AFHS on lymphocyte proliferation, interleukin-1 (IL-1) and IL-2 activity, pathologic section of ankle joint, and analgesic effect of AFHS in model rat. Results: AFHS could reduce the inflammatory pathologic response of ankle joint, it functions well as analgesics, the analgesic rate being 65%, AFHS could also improve T-lymphocyte proliferation, improve IL-2 activity and inhibit IL-1 activity, as compared with the control group, the difference was significant (P< 0.01 ). Conclusion: Through regulating the immune function of organism, AFHS could improve the local pathologic response so as to antagonise against rheumatism, therefore, it is a good anti-rheumatism herbal medicine.更多还原
