萆薢总皂苷合用牛膝总皂苷降血尿酸和抗炎作用的组方合理性研究

目的探讨牛膝总皂苷和萆薢总皂苷降低小鼠血尿酸和抗炎作用的组方合理性及剂量配比。方法采用尿酸或酵母膏致小鼠高尿酸血症模型以及二甲苯致小鼠耳肿胀模型,按照Codrug软件,得优化组方。结果萆薢总皂苷组、牛膝总皂苷+萆薢总皂苷组和阳性对照组小鼠血清尿酸水平明显降低(P<0.01),牛膝总皂苷480、240、120mg.kg-1组小鼠血清尿酸水平与模型组比较差异无显著性。牛膝总皂苷、萆薢总皂苷对小鼠耳肿胀均有明显的抑制作用,两者合用抑制率强于单药组,两药配伍理论优化剂量为牛膝总皂苷为120mg.kg-1,萆薢总皂苷为240mg.kg-1。结论萆薢总皂苷能降低高尿酸血症小鼠血清尿酸水平,而牛膝总皂苷对小鼠血清尿酸水平无明显影响。两者均有较强的抗炎作用,合用抗炎作用增强,优化组方为牛膝总皂苷∶萆薢总皂苷=1∶2。

Studies on the rationality of TSD combined with TSA on reducing serum uric acid and anti-inflammatory in mice

Aim To investigate the rationality and the dose of TSD combined with TSA on reducing serum uric acid and anti-inflammatory.Methods Mice hyperuricemic models were made by uric acid intraperitoneal injection or yeast extract paste intragastric administration.Mice ear swelling model was induced by locally painting dimethylbenzene.Optimized combination dosage of TSD and TSA was obtained using the Codrug software.Results In the mice hyperuricemic models,the serum uric acid in TSD group,TSD plus TSA group and positive control groups was significantly reduced compared with the model group(P<0.01).The serum uric acid level in 480、240、120 mg·kg-1 TSA groups shows no significant difference compared with the mod-el group.Moreover,the inhibitory rate of ear swelling in the TSD plus TSA group showed some advantage compared with that in the TSD or TSA group in the mice ear swelling model,and TSA120 mg·kg-1 plus TSD 240 mg·kg-1 reached the maximal inhibitory effect.Conclusions TSD might reduce the serum uric acid level in hyperuricemia mice;meanwhile,both TSD and TSA had anti-inflammatory effect,TSD plus TSA enhanced the anti-inflammatory effect compared with any of the two drugs.In these models,the best proportion of TSA and TSD was 1 ∶2.
