The effect of F 1C on joint swelling and the immune respones of AA rats were evaluated by lymphocytotic reaction, flow cytometry, and ELISA. Results F 1C by ig administration to AA rats decreased the primary joint swelling of AA rats, stronger than TW and weaker than CsA, promoted the decreased splenocyte proliferation induced by Con A, and inhibited the augmented thymocyte proliferation induced by Con A in AA rats. The evaluation in vitro showed the F 1C inhibited the augmented thymocyte proliferation from AA rats and promoted the deficient IgG produced by splenocyte from AA rats.

结果 ig给予F1C(30mg／kg)对AA大鼠原发性足肿胀具有明显的治疗作用，该作用较TW强，较CsA弱；F-1C对AA大鼠低下的脾细胞增殖反应具有改善作用；对亢进的胸腺细胞增殖反应具有抑制作用。F-1C体外对AA大鼠低下的脾细胞产生IgG水平具有明显的促进作用，并能抑制亢进的胸腺细胞增殖反应。
