摘要: 目的:研究萆薢总皂苷(total saponin of dioscorea,TSD)的抗炎镇痛作用。方法:尿酸钠(monosodium urate,MSU)分别致大鼠急性痛风性关节炎模型和小鼠皮下气囊炎症模型,醋酸和热板法分别致小鼠疼痛模型;酶联免疫吸附测定(ELISA)法测定IL-1β、IL-18和前列腺素E2(prostaglandin E2,PGE2)水平。结果:TSD能明显降低大鼠关节肿胀度,降低关节浸出液中IL-1β和IL-18水平(P<0.01或P<0.05),减轻小鼠皮下气囊炎症,降低气囊炎性渗出液中PGE2和IL-1β水平(P<0.01或P<0.05),显著提高热板法小鼠痛阈值,减少醋酸诱导的小鼠扭体次数(P<0.01或P<0.05)。结论:TSD具有较强的抗炎镇痛作用,可能与抑制炎性因子IL-1β、IL-18和PGE2合成与释放有关。

Abstract: AIM: To study the anti-inflammatory and analgesic effects of total saponin of Dioscorea(TSD). METHODS: The rat acute gouty arthritis (AGA) and the mice air-pouch inflammation models were induced by monosodium urate(MSU), the pain models were adopted including the hot-plate and acetic acid-induced writhing test in mice. Then the content of IL-1β, IL-18 and PGE2 levels were determined by ELISA. RESULTS:TSD significantly inhibited the MSU-induced ankle swelling and air pouch inflammation in mice(P<0.01 or P<0.05). Meanwhile, TSD markedly reduced the levels of IL-1β and IL-18 in synovial fluid exudates and IL-1β and PGE2 in air pouch exudates (P<0.01 or P<0.05).In addition, TSD remarkably suppressed acetic acid-induced writhing response and prolonged pain threshold in hot plate assay(P<0.01 or P<0.05).CONCLUSION: TSD has anti-inflammatory and analgesic effects, which are mainly relevant to the inhibition of the synthesis and release of inflammatory factors IL-1β, IL-18 and PGE2.

Key words: total saponin of Dioscorea, anti-inflammatory, analgesic
