龙牙楤木总甙(As)显著抑制PCA反应、Porssman皮肤血管炎、大鼠迟发型皮肤超敏反应、佐剂关节炎、Arthus反应、反向被动Arthus反应。但攻击前ig As对PCA反应,致敏前后ig As对Arthus反应和对Arthus反应大鼠血清中免疫复合物均无明显影响。
Aralia xylostella significantly inhibited PCA response, Porssman cutaneous vasculitis, delayed type hypersensitivity in rat, adjuvant arthritis, Arthus reaction, and reverse passive Arthus reaction. However, igAs did not respond to PCA before challenge, but had no effect on Arthus before and after sensitization and immune complexes to Arthus in rats.
