OBJECTIVE To explore the effect and mechanisms of LW-AFC,a new formula derived fromLiuwei Dihuang decoction,on chronic unpredictable mild stress(CUMS)-induced mood and *** impairment in *** C57 BL/6 J mice were randomly placed into seven groups(n=10):normal control group,CUMS group,Fluoxetine(10 mg·kg^(-1),once per day) group,Liuwei Dihuang decoction group(LW,10 g·kg^(-1),once per day),and LW-AFC(0.8 g·kg^(-1),1.6 g·kg^(-1),3.2 g·kg^(-1),once per day) *** stressed group was given CUMS for 4 weeks to set up a chronic multiple-stressed *** and LW-AFC was oral administered a week prior to CUMS and until the end of the study(a total of 35 d),while fluoxetine was administrated orally for 4 *** anxiety behavior was analyzed using the open field test(OFT) and elevated plus maze test(EPM).The depression behavior was *** using the sucrose preference test(SPT) and forced swimming test(FST).Spatial cognition was evaluated using Morris water maze(MWM) test and working memory was evaluated using new object recognition test(NORT).RESULTS CUMS for 28 d increased depressive-and anxiety-like ***-AFC(1.6 g·kg^(-1)) significantly increased the numbers of entries into the open arm and time in the open arm of CUMS mice(P<0.05).LW-AFC(3.2 g·kg^(-1)) increased sucrose consumption and *** the immobility time of FST(P<0.01) of CUMS *** MWM test showed that spatial learning andmemory in CUMS mice were remarkably affected relative to controls,whereas LW-AFC(3.2 g·kg^(-1)) *** cognitive functions(P<0.05).CONCLUSION The mood and theability of learning and memory of thestressed group can be affected after exposure to *** administration of LW-AFC *** improved CUMS-induced impairments of mood and cognition in mice.

合成和表征了超高交联树脂AM-1,以大孔吸附树脂AmberliteXAD-4为参照,比较研究了其在水溶液中吸附邻硝基苯酚,对硝基苯酚的吸附行为和热力学性质,测定了不同温度下的平衡吸附量,Langmuir模型和Freundlich模型均能很好拟合。利用Freundlich模型求得△H、△G、△S。研究发现,AM-1型树脂比表面小于XAD-4型树脂的比表面,而吸附能力却更强。这得益于其更多的微孔体积及表面活性基团。
