刺山柑在吐鲁番地区维吾尔族民间药用价值研究

刺山柑(capparis spinosa L.)是全世界公认的民间药用植物,具有较高的药用价值.采用民族植物学的关键人物访谈法,对该物种在新疆吐鲁番地区维吾尔族民间的医药作用进行了调研.结果表明,刺山柑的叶、根、根皮、花、果实及种子在民间医药中的处方有3种单方和4种复方.其中的单用刺山柑能治疗风湿病、慢性关节炎及肩周炎;而刺山柑与14种植物混合用的4种复方能治疗11种疾病.初步揭示了刺山柑在吐鲁番维吾尔族的民间处方及医药作用,为新药品及保健品的开发提供理论资料.     

干燥工艺对稻谷发芽率影响的研究

利用薄层干燥试验台，采用二次回归正交组合设计试验对辽宁省稻谷主要品种942进行研究。分析了热风温度、表现风速、初始水分、干燥时间对稻谷发芽率损失影响的规律，建立了稻谷发芽率损失回归方程，在干燥时应采用低温干燥，以保证其发芽率。利用贡献率法确定各因素在二次非线性模型中的主次关系为热风温度、初始水分、表现风速、干燥时间，为进行辽宁省稻谷深床干燥研究提供了理论依据。     

Science Letters： A synthetic Toll-like receptor 2 ligand decreases allergic immune responses in a mouse rhinitis model sensitized to mite allergen

It has been proposed that activation of Toll-like receptors （TLRs） plays crucial roles in the polarization of adaptive immune responses. A synthetic Toll-like receptor 2 （TLR2） ligand, Pam3CSK4, has been reported to modulate the balance of Th1/Th2 responses. We evaluated the modulation effect of Pam3CSK4 on allergic immune response in a mouse rhinitis model sensitized to house dust mite allergen （HDM）. Mice were sensitized and challenged with Dermatophagoidesfarinae allergen （Der f）, and then the allergic mice were treated by Pam3CSK4. Nasal allergic symptoms and eosinophils were scored. Der f-specific cytokine responses were examined in the splenocytes and bronchoalveolar lavage fluid （BALF）. Serum level of total IgE was also detected. After establishing a mouse allergic rhinitis model with HDM, we have showed that Pam3CSK4 treatment not only ameliorated the nasal allergic symptoms remarkably but also decreased the eosinophils and total inflammation cells in BALF significantly. Analysis of cytokine profile found that IFN-7 released from either BALF or stimulated splenocytes increased markedly in Pam3CSK4-treated mice, while IL-13 decreased significantly. Moreover, serum level of total IgE was significantly lower in Pam3CSK4-treated mice than in the untreated. Thus, in an allergic rhinitis mouse model developed with HDM, Pam3CSK4 was shown to exhibit an antiallergic effect, indicating its potential application in allergic diseases.
