Methods： The antinociceptive effect of AV（400, 600 and 800 mg/kg） was investigated in mice using the acetic acid-induced writhing, formalin-induced nociceptive, and hot plate tests. Phlogogen-induced paw edema using carrageenan, dextran, or compound 48/80 as phlogogen was used as inflammatory models to evaluate AV＇s anti-inflammatory effect. Additionally, the bioactive substances glucosamine（GLc N） and taurine in AV were determined using high-performance liquid chromatography. Results： Oral treatment of the mice with AV（600 and 800 mg/kg） significantly reduced the number of writhes in the acetic acid-induced writhing test（P〈0.01） but not the hot plate test（P〉0.05）. All doses tested significantly inhibited paw-withdrawal during the second phase of the formalin-induced nociceptive model（P〈0.01）. AV demonstrated a strong anti-inflammatory effect in all those inflammatory models（P〈0.05）. Conclusions： AV has antinociceptive and anti-inflammatory effects, providing scientific evidence of the efficacy of its traditional use in pain treatment. Furthermore, GLc N and taurine contribute, at least in part, to the anti-inflammatory activity of AV.展开更多
